How to properly do ventilation in a Russian bath: general rules and detailed diagrams of the device. Do-it-yourself ventilation device in the steam room Ventilation diagram in the steam room

Ventilation in the bathhouse is simply necessary. First of all, ventilation is intended to ensure the safety of people who take bath procedures.

Everyone knows that when breathing a person inhales oxygen and exhales carbon dioxide. In a tightly closed room, after some time he will begin to suffocate. And in a steam room, where the temperature and concentration of water vapor are high, this will begin to happen even faster.

Relaxing on the shelf, you won’t have time to get to the rescue one. The cost of an incorrect ventilation device can be prohibitive.

The second important factor is wood rotting. Enjoying and benefiting from bath procedures while smelling rot and mold is very problematic. Therefore, proper ventilation in a Russian bathhouse is the key not only to its benefits, but also to the health of vacationers.

Experts believe that a ventilation device in a bathhouse in which the air in the room is changed three times in one hour can be considered correct. The ventilation scheme in the bathhouse is selected depending on the type of structure and materials used in the construction of the walls.

General principles of ventilation in a bathhouse

The correct design of a bathhouse and ventilation in it, regardless of the type of structure, is based on the following basic principles:

The fresh air that enters the steam room should not disturb its temperature regime;
Exhaust air, which contains the most carbon dioxide, must be removed from the room;
The arrangement of air in the steam room should be layered: the hottest air is under the ceiling, on the bench it is as comfortable as possible and the coldest air is near the floor.

Note!
There should be no draft in the steam room!

If all these principles are followed, then bath procedures will bring the maximum effect for which they are designed - restoration of mental and physical strength.

Ventilation device in a free-standing wooden bath

The tree is considered ideal building material for a bath. Wooden walls “breathe”, so the issue of air exchange is partly solved naturally.

However, even in a wooden building in a steam room, ventilation is necessary. At a minimum, for quickly drying the wood after taking bath procedures.

Work plays a major role in air exchange processes sauna stove. When water is poured onto a column of hot steam is created, which rises upward. As it cools, it lowers, pushing the used air out of the steam room.

Together, the above factors make it possible to create the necessary humidity and temperature in the steam room, and ensure normal air circulation.

Let's take a closer look at the ventilation system in wooden baths. The main tasks for us, naturally, will be to ensure the influx fresh air and removal of what has already been used. Our instructions will help you cope with these tasks.

Ensuring air flow

The correct frame is laid in such a way that the lower crowns are free. With this installation, access to fresh air from the street is ensured.

In addition, around the steam room door, in any case, there will be gaps sufficient for its entry. The stove in such baths is placed closer to the door so that it heats up immediately.

If the steam room is designed for 6 or more people, a separate air duct is connected to the heater, which supports the combustion process. If you make this air duct double, then the problem of fresh air supply is solved once and for all.

Exhaust air removal

If the heater is heated directly from the steam room, then the exhaust air is exhausted through the firebox into. At correct installation oven, no additional holes required.

In order to dry the room after completing the bath procedures, a small hole (up to 200x200 mm) can be cut in the wall. During the heating and operation of the steam room, it is closed with a special plug.

If the steam room has a window, such a hole is not needed. Sometimes a window from the steam room is cut into the washing room, and in the washing room either a through hole to the street or another window is made. Thus, when drying, two birds are killed at once, both the steam room and the washing room are dried.

Thus, the myth that ventilation is not needed for a wooden bathhouse is confirmed if the following conditions are met:

The steam room is designed for 2-4 people;
The lower crowns of the frame are laid freely;
The stove-heater is heated directly from the steam room;
There is a hole or window in the wall for ventilation.

Actually, such family baths are usually built on personal plots.

Ventilation device in a free-standing brick bathhouse

A brick structure, as well as a structure made of foam concrete, expanded clay blocks and other permanent structures, is another matter. Ventilation in a brick bath is more complex.

The first difference is that floors in a brick building must be ventilated. The thing is that the floors in the bathhouse are constantly in contact with water, and if they are solid, then the boards will have to be replaced approximately every three to four years. ABOUT unpleasant odors and you don’t even have to talk about mold.

Ventilation of the floor in the bathhouse is laid at the stage of foundation construction. To do this, special holes are made in the foundation on opposite sides. These holes will provide through air circulation under the floor and drying of the joists.

The second difference is the mandatory presence of special supply and exhaust openings in the steam room. There may be several of them. Two supply holes are made at floor level and covered with grates to prevent rodents from entering.

There are 4 most popular schemes for ventilation in a bathhouse, from which you can choose the most suitable one for you.

Scheme No. 1. The supply hole is located behind the stove at a distance of 50 cm from the floor. An exhaust hole is cut in the opposite wall no higher than 30 cm from the floor. A bath fan is installed on it, which will ensure air circulation.

According to this scheme, the air in the steam room is heated evenly, the incoming air is heated by the stove and rises. As it cools, it falls down and exits through the outlet. The lower it is located, the stronger the air flow will be. When using a fan, a ventilation valve can be installed at the outlet.

Scheme No. 2. Suitable for those baths where the stove is heated from the steam room. In this case, the influx is made directly under the stove. The flow of fresh air is sucked in by the stove, supporting combustion, and provides an influx directly into the room.

The exhaust vent is located above the floor and connected to it corrugated pipe, which rises up to the roof level and opens onto the street. In other cases ventilation duct made in the wall.

Note!
If the walls of the bathhouse are made of expanded clay concrete blocks, then it is best to install ventilation ducts during construction.

Scheme No. 3. According to this scheme, ventilation for the bathhouse is arranged through cracks in the floor. In this case, the supply hole is made in the wall near the stove at a height of 30-50 cm from the floor. The air, heating up, rises and exits through the cracks between the floor boards into the basement. It is thrown out from the basement space using a special pipe.

Note! For the normal functioning of this type of ventilation, it is necessary to leave 5-10 mm gaps between the floorboards.

Scheme No. 4. This scheme is suitable in cases where the stove also heats other rooms.

Fresh air is sucked in by the stove through holes in the floor and, passing through the firebox, goes out into the steam room and into the washing room. It is removed from the premises through openings located below, above the floor level.

There are also combined ventilation schemes, but to install them yourself, you need to consult with a specialist.

The video in this article will help you understand clearly how ventilation is arranged in a bathhouse.

High-quality ventilation system – required element steam rooms The absence or improper organization of ventilation in the bathhouse is dangerous to human health. A properly designed system will protect people from carbon monoxide and improve the comfort of staying indoors. We will talk further about the features and technology of installing a ventilation system in a bathhouse.

Characteristics of proper ventilation for a steam room

Proper ventilation in the bathhouse performs several functions at once:

provides the room with oxygen;
improves the comfort of staying in the steam room;
removes carbon monoxide;
allows for economically efficient use of firewood;
distributes air flow evenly;
protects the building from the formation of mold or mildew.

The most the best option ventilation in the bathhouse is supply and exhaust. For these purposes, arrange:

supply opening - through them a flow of fresh air is organized into the steam room, a fan with a ventilation tube is installed, additional air flow is provided by open vents or through the door;
exhaust hole - removal of heated air from the room, through a firebox, blower or devices that improve draft.

For improvement supply and exhaust system ventilation is used various ways. We invite you to familiarize yourself with one of the most effective ventilation systems:

1. The supply openings are located at the bottom of the room, next to the firebox.

2. Exhaust holes are strictly on the opposite side from above. It is possible to organize two holes at once for better air control.

3. The height of the exhaust opening determines the level of draft. If the ventilation opening is low, further strengthen the system with a ventilation pipe.

4. Using special dampers, the air supply from the room is controlled.

5. The air in the steam room is renewed every 2-3 hours.

In addition, the individual parameters of the ventilation system are determined by the type of room and bathhouse option. For example, in a Russian bathhouse, periodic ventilation will help to renew the air. In addition, the size and installation location of the firebox is taken into account; in relation to this parameter, two types of ventilation are organized.

How to make ventilation in a steam room with a separate firebox

We offer an option for organizing ventilation in a steam room, the firebox of which is located in an adjacent room. This scheme is popular in ordinary Russian baths. A furnace tunnel is used to lead the firebox into the adjacent room. Among the advantages of this arrangement of the furnace, we note:

no trash in the steam room;
the door to the room opens only upon entry;
possibility of installing heat-resistant glass for admiring an open flame.

To install supply openings in a room, two methods are used:

1. Arrangement of a ventilation duct in the underground space. Bringing it out in front of the furnace room, installing ventilation grilles on the duct.

2. Floor ventilation supply.

Install the hood on the opposite wall, diagonally in relation to the supply opening.

The main quality of organizing proper ventilation is that the supply openings must coincide in area with the exhaust openings.

Ventilation diagram in a steam room with an indoor firebox

If the stove-heater is located directly in the steam room, then the organization of ventilation occurs differently. In this case, air flows through the ashpit solve the issue of natural ventilation. This method is appropriate if the fire in the stove is constantly on.

If there is no chimney in the bathhouse, and the stove operates in short-term mode, use a more advanced ventilation system. Familiarize yourself with the technology of arranging a ventilation system in a steam room:

1. Build a special brick podium on which the stove is installed. With its help, a ventilation duct is connected to the stove.

2. Lay the ends, build another box of bricks. As a result, the first structure was installed at the top of the stove channel, and the second - to the steam room door.

3. On the wall adjacent to the regular room, build doors where the masonry passes through. They warm up next room, if necessary.

4. A stove is installed on the podium; it can be mounted on a corner or on steel pictures. Finish the oven with brick, install a brick screen with two convection valves.

5. The exhaust ventilation system operates due to the furnace firebox.

Correct installation of the ventilation system is based on its correct adjustment. General rules for controlling the ventilation system:

at the beginning of the furnace fire, all openings, both supply and exhaust, are closed;
wait until the temperature increases, then adjust the ventilation holes with the valves;
if it is necessary to increase the volume of oxygen in the room, open the inlet;
Upon completion of work, open the doors for better ventilation of the steam room.

Steam room ventilation photo:

To determine the temperature and humidity in the room, use special instruments. An alcohol thermometer or electric type. Please note that the use of the mercury version is strictly prohibited. Use a hygrometer to determine the humidity level.

The operating principle of the ventilation system is based on the following factors:

by heating the oven, the air gradually heats up and exits through the convection door;
the bottom door remains open until the oven is completely warmed up;
close the door from below and work with the top hatch;
during the vaping process, only the blower installed on the box opens;
After using the steam room for its intended purpose, ventilate the room well.

Do-it-yourself ventilation device in the steam room

The main functions of the ventilation system in the bathhouse:

air supply during bath procedures;
high-quality room drying.

The ventilation system in the bathhouse should not:

violate the temperature of the room while taking bath procedures;
separate temperature flows, that is, cool air is closer to the floor, and warm air is located above;
remove unexhausted air from the steam room.

In addition, the lack of ventilation leads to the appearance of unpleasant air in the room, the formation of mold and mildew, which are harmful to human health.

Let us highlight three main types of ventilation in the steam room:

a natural option is to supply air flows through a pressure difference;
mechanical option - air supply using special mechanisms, when measuring these characteristics with instruments;
combined option - creating artificial pressure with fans and hoods.

There are two types of air transportation in a room: supply and exhaust. For these purposes, equip a hole located diagonally with respect to the inlet.

It is not recommended to install an exhaust vent in the steam room on the ceiling; this ventilation system increases the time it takes to warm up the room. It is rational to install the hood under the ceiling, additionally equipping it with a damper to regulate the draft.

In addition, provide a ventilated floor in the bathhouse. Thus, the period increases flooring, since it is in constant contact with water. Recommendations for arranging floor ventilation:

1. During the installation of the foundation base, ensure ventilation of the floors and build vents from the basement.

2. Build ventilation holes on opposite walls to ensure air flow. Install grilles on them to prevent rodents from entering.

3. The finished floor should be slightly higher in level than the ash pit is located. Thus, it will function as a hood.

4. Install wooden boards with a small gap, at least half a centimeter.

5. After taking bath procedures, ventilate the room well and dry the floors.

Another way to organize a ventilation system in a bathhouse is “According to Bast”. In this case, fresh air enters the room from the furnace space, and exhaust comes from an opening located near the door. For these purposes, build an exhaust duct made of wood, lined with foil inside.

Build a ventilation duct under the floor next to a metal sheet to prevent heat from entering it. The size of the structure should not exceed twenty percent. Adjusting the flow of fresh air through such a system is quite simple. It is enough to open the ventilation hole and the blower. In addition, it is possible to avoid the accumulation of unpleasant aroma in the steam room. This method of organizing ventilation is appropriate if the firebox is located directly in the steam room.

DIY methods for organizing ventilation in a steam room

Install the inlet hole under the stove 50 cm from the floor, and the outlet on the opposite side, 30 cm from the ceiling. Forced movement of air masses is provided by a fan. Thus, it is possible to ensure uniform heating of the air. The height of the first hole regulates the draft force of natural ventilation.

Two ventilation holes located on one wall, always opposite the stove. The inlet is installed at a distance of thirty centimeters from the floor, and the outlet - thirty centimeters from the ceiling. Install a fan in the outlet, the cooled air entering the room collides with the stove, heats up and goes outside.

Place the inlet hole behind the stove, at a distance of about twenty centimeters from the floor. The inlet is installed at the same height, only near the ceiling of the opposite wall. A hood is installed in the second hole. The principle of operation of the system is based on cooled air entering the steam room, passing through the oven and being drawn out by a second hole.

This method is relevant for a steam room with a floor that has holes for water drainage. The inlet is installed behind the stove, and the outlet is a drain pipe through which air is discharged outside.

Relevant for a bathhouse with a constantly running stove. The inlet hole is arranged opposite the stove, and the vent with chimney act as an outlet

If you need to increase the temperature in the steam room, just close all the plugs. After taking bath procedures, they are removed. It is quite possible to organize these ventilation schemes yourself, without purchasing expensive devices and special material investments.

How to make a vapor barrier for a steam room with your own hands

Vapor barrier in the steam room allows you to maintain optimal temperature premises. They will help you create a high-quality vapor barrier special materials in the form of vapor-proof films, insulation and waterproofing. The film protects the insulation from the penetration of water vapor, while not allowing moisture in the hot air to pass through.

A well-equipped vapor barrier and ventilation system increases the service life of the room itself and its exterior finishing. Since hot air rises upward, first of all, properly vapor barrier the ceiling.

For these purposes, use racks, boards, about 6 cm thick. They are covered on top with aluminum-based foil, high-density cardboard or wax paper impregnated with drying oil. After fixing one of these materials, the ceiling is finished with clay and insulated.

In addition, edged boards will help to vapor barrier the ceiling. Cardboard impregnated with drying oil is installed on the boards, which is then lined with wooden clapboard.

Expanded polystyrene boards are a modern replacement for soft clay and have good thermal insulation and performance characteristics.

The following are used as vapor barrier materials for steam room walls:

Glassine and roofing felt are rarely used for thermal insulation of steam rooms. This is explained by the fact that when heated strongly, they release toxic substances and unpleasant odors. The steam room is vapor-insulated with special foil materials. There are combined methods of steam and heat insulation. For example, NPP polypropylene, among its advantages we note:

excellent resistance to moisture;
resistance to increased temperature;
laminated coating prevents the development of mold and mildew;
combined thermal vapor barrier.

In addition, it is possible to use rolled vapor barrier in the form of rolled foil or fiberglass boards. For sealing joints between vapor barrier materials, use foil tape.

The plates are installed on the ceiling with a small compensation gap of 20 mm. This reduces the impact of moisture on these areas. Please note that the vapor barrier in the steam room must be securely hidden behind the main finishing material, and a high-quality ventilation system is its complement.

Do-it-yourself ventilation in the steam room

Baths, saunas and swimming pools A high-quality ventilation system is an essential element of a steam room. The absence or improper organization of ventilation in the bathhouse is dangerous to human health.

Ventilation in a bathhouse with your own hands: how to do it right

Why do you need to worry about how to properly ventilate a bathhouse? Not only the maintenance of a comfortable temperature in the dressing room, washing room, steam room, relaxation room, but also the safety and service life of the building and its parts depends on how correctly the ventilation in the bathhouse is arranged. When designing a bathhouse and starting its construction, you should remember that ventilation in the bathhouse with your own hands must be done taking into account certain subtleties and nuances. With your own hands, using instructions, photos and videos, you can complete all stages of installing ventilation in a bathhouse and steam room.

Properly arranged ventilation in the bathhouse will ensure comfortable temperature inside the steam room and will extend the life of the wooden elements

The principle of operation of the ventilation system in the bathhouse

The operation of the ventilation system is based on well-known physical laws, and its design is simple and understandable. For continuous air circulation, two types of openings are required:

Supply openings are needed to allow fresh air to enter the room. With proper ventilation in the bathhouse, they should be located as close to the floor and near the stove as possible. With this arrangement, the incoming air quickly heats up and a high temperature is stably maintained in the bath.

The direction of movement of air masses inside the steam room

Exhaust holes are designed to remove superheated humidified air and carbon monoxide from the steam room. They should be installed as high as possible, that is, just below the ceiling level, and located opposite the supply openings in order to create and maintain constant air exchange.

Advice! An exhaust vent in the ceiling will quickly cool the room, so this location is undesirable.

There are no difficulties with the fundamental localization of supply and exhaust openings when installing ventilation in a bathhouse with your own hands. But the task of maintaining a high temperature in the steam room while simultaneously effective removal from it exhaust air and carbon monoxide is not easy.

You also need to pay attention to maintaining a temperature that is comfortable both for sanitary and hygienic procedures and for relaxation in all parts of the bathhouse: dressing room, washing room, relaxation room. And if you have to create and implement a ventilation scheme in a bathhouse with your own hands, you should think about performing the work correctly.

Diagram of proper air circulation in the bath

Types of ventilation

There are two types of ventilation:

Which one to choose when installing a ventilation system with your own hands depends on the design of the bathhouse and the volume of its premises.

Ventilation system with electronic control unit

Natural ventilation

This type of ventilation works due to the difference in temperature and pressure inside and outside the room. The efficiency of its operation depends on the placement of the air inlet and outlet holes. The most suitable solution is that the supply openings are located near the floor, at a height of 250-350 mm, next to the stove, and the exhaust openings are on the opposite wall, 150-200 mm below the ceiling level.

The best photos of finishing the bathhouse inside and a description of the stages of work. Sequence of actions when repairing a sauna. Recommended materials for use and installation rules. Waterproofing and insulation of walls.

Natural ventilation systems are not suitable for ventilating a steam room or steam room, since the cold air in this room collects near the floor, and the hot air in the upper part. Setting up the movement of air flows is accompanied by difficulties, but with the correct arrangement of ventilation elements in a Russian steam bath, it is possible to cope with this problem with your own hands.

Natural ventilation is not suitable for a steam room; it is advisable to arrange it in a relaxation room

Forced ventilation

For this type of ventilation in the steam room of a Russian bath or sauna, two subtypes can be distinguished:

Ventilation using special electronic systems that control air temperature and humidity, automatically regulating its flow and filtration. Such systems are quite expensive, and their use is often beyond the budget.
A combined ventilation system, when, through the use of fans, the effect of natural ventilation is obtained.

Location of ventilation ducts inside the walls of the bathhouse

Dependence of the bathhouse ventilation system on the type of building

Natural ventilation, provided correct location vents and their size corresponding to the volume of the premises, functions well in a Russian bathhouse assembled from logs or timber.

The frame building is a sealed structure. It is advisable to use forced ventilation in frame baths. The supply opening in the outer wall of the steam room should be additionally equipped with a blower fan.

In a building made of brick or foam blocks, only forced ventilation is possible.

The type of ventilation system is selected depending on the materials from which the bathhouse is built

Planning a bath ventilation system: subtleties and nuances

Before you start choosing a ventilation scheme in a bathhouse and arranging its structure with your own hands, you need to understand the subtleties and nuances of design.

Fact! Even small errors in the layout of the supply and exhaust openings lead to undesirable consequences. In the steam room, the constant air temperature will either decrease or the concentration of carbon monoxide will increase.

When building any bathhouse - ventilation of the bathhouse and its circuit diagram laid during the construction process. The question “how to make ventilation in a bathhouse” should be resolved at the design stage.

Ventilation ducts of the dressing room, washing room, steam room, rest rooms and openings for the influx of fresh air and removal of the mixture carbon monoxide with exhaust humid and hot air masses should be laid at the appropriate stages of construction. Valves and grilles for regulating the sizes of supply and exhaust openings and sections of ventilation air ducts are installed already at the stage finishing premises.

Planning the ventilation system must be carried out at the stage of developing a design project for a bathhouse

Basically, the functioning of bath ventilation depends on two factors:

the dimensions of the ventilation openings - both supply and exhaust - which are determined by the volume of the room, be it a dressing room, washing room, steam room or relaxation room;
relative position of ventilation holes.

Vent Sizes

The size of the ventilation holes depends on the volume of a particular room: dressing room, steam room, washing room or rest room. Both accurate calculation of the size of these openings and the ability to change it are very important. To adjust the gaps in the openings, gates and grilles are installed.

Ventilation hole with slider to regulate the volume of fresh air flow

It is necessary to take into account that with large ventilation windows it will be difficult to heat the room to the correct temperature. There will either be a danger of constant excessive consumption of fuel and electricity, or difficulties in adjusting the cross-section of the ventilation ducts, that is, the distance to which each opening will need to be opened with your own hands.

Advice! The area of the ventilation opening is determined at the rate of 24 cm² per 1 m³ of the volume of the ventilated room. For good draft of fresh air from outside, the exhaust hole must be larger than the inlet.

If the area of the ventilation openings is insufficient, the temperature, air humidity and carbon monoxide concentration in the room can rise to critical values.

The optimal size of the ventilation opening is calculated at the rate of 24 sq. cm per 1 cubic meter of room volume

Relative position of ventilation holes

The operation of any ventilation system is based on the replacement of masses of heated air that move under the pressure of air coming from outside - colder and heavier. It is important to provide the ability to regulate the direction of the heat flow emanating from the stove installed in the bathhouse. Ventilation in a steam room is often equipped with not one inlet, but two precisely for this reason. To localize heat flows, it is enough to use valves to create a gap of a certain width in one of them or in both.

Layout of ventilation holes inside the steam room for the influx of fresh air and removal of contaminated air

Ventilation in a Russian bath

The quality of the ventilation system of a bathhouse, designed and installed with your own hands, is laid down at the project stage.

The air currents circulating in the rooms will have different temperatures, but the discomfort from this should be felt as little as possible.

Advice! Comfort in the bathhouse depends not only on the absence of sudden changes in temperature “horizontally,” that is, when moving from one room to another: from the rest room to the dressing room or from the steam room to the washing room. A gentle movement of air masses vertically is necessary: the air temperature near the floor should not be much lower than the temperature at the level of average human height.

The microclimate in the bathhouse directly depends on the number of ventilation holes, their size and location

The uniformity of the intake, mixing and removal of air masses depends on the number of supply and exhaust openings, their sizes, location relative to each other and heating devices, as well as equipped with additional control devices.

Basic diagrams of ventilation in a bathhouse

Any sauna ventilation scheme is developed with one purpose - maintaining temperature, humidity and fresh air in the steam room. The bathhouse premises, and especially the steam room, are exposed to water and steam, and therefore require periodic ventilation and drying. But ventilation and drying will be ineffective if proper ventilation is not organized in the bathhouse. Proper and constant ventilation of a steam bath significantly reduces the consequences of wood absorbing moisture.

The main task of sauna ventilation is to maintain temperature, humidity and air freshness in the steam room

Floor ventilation in the bathhouse

Air exchange in bath rooms is facilitated by the installation of a ventilated floor.

Wooden floors that are in constant contact with water become unusable after 5 years. Requirements necessary for floor ventilation:

to create a flow, make small vents in the foundation of the bathhouse;
lay the floor, leaving gaps of up to 1 cm between the boards;
lay inlet openings in parallel walls (not forgetting to protect them with bars from rodents);
In order for the furnace to operate with an additional hood, lay the finished floor above the level of the blower;
After using the sauna, leave the doors open until the floor in the room is dry.

Diagram of the ventilation system in the sauna

Ventilation in the sauna dressing room

With your own hands, if you have photo and video instructions, it is easiest to do ventilation in the relaxation room of the bathhouse and in the dressing room, since there is no direct contact with water. Natural or combined type of ventilation is used, when fresh air enters through supply channel and is removed using a fan through the exhaust duct of the steam room, vestibule or bathroom. It is also possible to install ventilators, which will require direct access to the street and a power connection.

The dressing room can be equipped with natural or combined type of ventilation

Ventilation in the washing bath

For air exchange in the washing room, a system is often made forced ventilation, which is driven by an electric motor. Air flows are directed towards the vestibule. The supply and exhaust ducts are made of the same cross-section, the inlet of the first is installed above the ground level (2 m), and the outlet of the second is above the roof.

Ventilation in the steam room of the bath

The microclimate requirements for the steam room are special. It must warm up quickly and be maintained optimal level humidity and no drafts. Therefore, the correct position and dimensions of the supply and exhaust channels, which are laid during construction, are relevant for the steam room. To regulate the inflow and outflow of air, valves in the vents are sufficient, but if the room is large, a blower or exhaust fan may be needed.

Scheme of ventilation arrangement in the steam room

The above general principles designing ventilation in a bathhouse, videos and photos attached to instructions from online or other resources should help those wishing to build a bathhouse with their own hands to bring this desire to a concrete embodiment.

Ventilation in a bathhouse with your own hands: how to do it right

Ventilation in a bathhouse with your own hands - why you need ventilation in a bathhouse, how to make ventilation in a bathhouse yourself, design principles, diagrams, instructions, photos, videos.

Do-it-yourself ventilation in the bathhouse

In the process of arranging a bathhouse Special attention it is necessary to pay attention to the issue of organizing high-quality ventilation. Without proper air exchange, it will simply be impossible to use the steam room normally. If desired, all work on installing the necessary systems can be done with your own hands. You just need to understand the order of installation and connection of the main units and do everything in accordance with the instructions.

Why is ventilation needed in a bathhouse?

Ventilation in the bathhouse is very important. To avoid lengthy and not very interesting explanations, you can consider everything using a specific example.

The bathhouse visitor is in a room filled with a large amount of hot steam. A person inhales this vapor. It is known that people breathe oxygen and exhale carbon dioxide. In the absence of sufficient air exchange, after some time a person will simply burn out.

That is why ventilation in the bathhouse should be as efficient as possible and made in full accordance with technology. There are several types of ventilation systems. Study the features of each option and choose the method that is most suitable for your case.

Ventilation in the steam room

Ventilation systems are installed to solve two main problems, namely:

ensuring receipt clean air to the bathhouse;
removal of exhaust air from the steam room.

Additionally, ventilation ensures faster and better drying of the steam room. It is necessary to study the features of existing ventilation systems and understand the order of their installation in order to obtain the most efficient and high-quality air exchange.

It is important that during operation of the ventilation system the temperature regime characteristic of the bath is not disturbed. Air exchange must be organized in such a way that there are no disturbances in the distribution of temperature flows in the bathhouse. Cool air in the steam room can only be located near the floor. And the higher you go to the ceiling, the higher the air temperature should be.

Ventilation should not remove clean air from the bathhouse. A properly equipped system supplies fresh air to the room and removes exhaust air. Errors during installation of the system will lead to extremely unfavorable consequences for both the bathhouse and its visitors.

Mold damage to wood

Main types of ventilation systems

There are several types of air exchange systems suitable for use in a bathhouse, namely:

natural ventilation. The operating principle of such a system is based on the use of the pressure difference inside the bathhouse and outside. The simplest and least effective option;

Exhaust fan from steam room

Exhaust air is removed from the bathhouse through a special ventilation duct. The air exchange installation technology requires that the box be installed diagonally to the supply opening through which fresh air enters the bathhouse.

Take care of ventilation in all areas of the bathhouse, and not just in the steam room. The dressing room, rest room and other areas of the bath should also be well ventilated.

What you need to know about floor ventilation?

Quite often, bathhouse owners forget that the floor of the steam room must also be well ventilated. Such forgetfulness leads to very rapid deterioration of floor structural elements and a general deterioration in the characteristics of the bathhouse.

Floors are constantly in contact with water. Without properly organized air exchange, the floor will collapse very quickly, and the floor covering will have to be replaced after 2-3 years.

You need to think about floor ventilation at the bathhouse construction stage, because... In a ready-made room, it will be much more difficult to create high-quality air exchange.

First stage. Make small vents in the opposite walls of the basement. It is best to provide these vents at the stage of construction of the concrete base of the bathhouse. Creating any holes in already finished design will lead to some reduction in the strength of the building.

Ventilation in the steam room

Second phase. Make one ventilation hole in opposite walls of the room being served. Through them, clean air will flow into the room. The holes must be through. It is recommended to close the finished channels with special ventilation grilles. Such protection will not allow all kinds of rodents and other pests to enter the bathhouse.

Ventilation in the bath

Third stage. When building a stove, make sure that its vent is slightly below the level of the finished floor. Thanks to this placement, the oven will also start working in exhaust mode.

Fourth stage. Lay floor boards. When laying them, you need to leave gaps about 7-10 mm wide. Water can flow down through these gaps. If the liquid lingers on the floor every time, the boards will rot very quickly.

Quite often, floor ventilation is arranged “according to Bast”. According to this technology, fresh air comes from under the stove, and waste oxygen is removed through an opening under the ceiling.

According to requirements fire safety There should be a metal sheet lying near the sauna stove. It is near this sheet that a hole is created to supply fresh air to the bathhouse.

To provide such air exchange, a special exhaust duct is required. You can buy a box at finished form or assemble it yourself from boards. Inner surface The exhaust duct must be covered with foil. The size of the box should be approximately 15-20% larger than the diameter of the chimney.

Ventilation “according to Bast” is the best option for those cases when the stove is located directly in the steam room. In such a situation, ventilation ducts can even be installed directly in the brick podium.

Pay attention to the installation location of the sauna stove. If the stove is located directly in the steam room, it means that natural air exchange is present initially. You just don’t need to rely solely on it - such ventilation only works when the stove is running.

The most optimal option for installing ventilation is to install air exchange channels on opposite walls of the bathhouse. They should be at different heights.

It is not recommended to place ventilation holes too high. Although in most other cases it is recommended to make an exhaust hole directly under the ceiling, slightly different rules apply in bathhouses. If you place the hood directly under the ceiling, hot air will escape from the room very quickly.

For baths, the optimal height for placing ventilation holes is a level of 1-1.5 m.

Installation guide for ventilation in a bathhouse

There are several simple ways organizations effective air exchange in the bath. Study each of them and choose the best one for your steam room.

First way. Create a hole to supply fresh air. It should be behind the stove, about half a meter from the floor. Make a hole for exhaust air exhaust on the side opposite to the inlet hole, at a height of approximately 30 cm from the floor level. Install the fan into the outlet.

Create a hole for fresh air

The lower you place the exhaust ventilation duct, the more intense the air exchange will be.

However, there is no need to be too zealous either. Try to make holes at the recommended height, because... such values are the most optimal. It is recommended to close the holes with ventilation grilles.

Second way. With this air exchange, both ventilation holes will be on the same wall. Work will be carried out with a wall located parallel to the stove. The exhaust duct is created at a level of about 30 cm from the floor, the exhaust duct is created at the same distance from the ceiling of the bathhouse. The exhaust vent is equipped with a fan. Close open channels with ventilation grilles.

Third way. Make a hole behind the sauna stove for air intake. Place the suction duct at a level of about 20 cm from the floor surface. The exhaust duct is made at approximately the same height, but in the opposite wall. The exhaust vent is equipped with a fan. Close open channels with ventilation grilles.

Fourth way. This air exchange option is perfect for baths, the flooring of which is laid with slots for water drainage. Make an inlet hole behind the stove unit at a distance of about 30 cm from the floor surface. In the case of such ventilation, an exhaust hole is not made - the exhaust air will leave the bathhouse through the cracks of the floor covering, and then be vented outside through a common ventilation pipe.

Ventilated floors in the bathhouse

Fifth way. This ventilation is ideal for baths with a constantly running stove unit. Install the inlet channel opposite the stove, about 30 cm away from the floor. The hood function will be performed by the oven.

Thus, the procedure for arranging ventilation is practically the same in all the considered methods. Each of them involves the creation of one or two holes; only the location and height of their placement change.

You can also make the holes yourself. Brick walls they can be easily passed through with a hammer drill, and logs with any suitable tool for this purpose, for example, a wood drill. It is recommended to insert plastic pipes into the finished holes. Don't forget about protective ventilation grilles. In the future, you are unlikely to be happy with uninvited guests in the form of rodents.

Ventilation in a bathhouse with your own hands - step-by-step instructions!

Find out in what order the ventilation in the bathhouse is connected with your own hands. Detailed Guide with a description of all stages of work. Photo + video.

When constructing and repairing baths, attention is paid primarily to construction materials, stoves, insulation and waterproofing. It is assumed that natural circulation There will be enough air for high-quality ventilation of the premises in the bathhouse. But this is absolutely not true, and if you approach the matter superficially, you can run into serious problems.

Peculiarities

Ventilation in a bathhouse can be done in various ways.

Its presence depends on:

distribution of heat flows inside;
comfort and safety of washables;
period of operation of the building.

Water and steam are continuously concentrated there, and the tree actively absorbs them. Even if you dry the building periodically, without establishing constant air movement, the effect will not be strong enough. To avoid dampness, you need to create a pair ventilation windows– one serves to bring in clean air from outside, and the other helps the heated air to exit, having absorbed a lot of water. When selecting the location of the openings, change areas that are particularly intensively ventilated. The use of a pair of outlet openings in the steam room and dressing room sometimes improves the orientation of the air flow in the required direction.

Certainly, great importance has both the size of each window and the ability to adjust the clearance. They are equipped with valves that can be opened fully or partially. The calculation of the volume of ventilation holes is based, first of all, on the area of the bathhouse premises. If you make them too large, mold will never appear on the floor and in the sink, but the steam room will take a very long time to heat up, and an unusually large amount of fuel or electrical energy will be consumed. Too much narrow windows will not allow the air inside to cool or become drier.

All deviations from normal parameters are strictly unacceptable, which eliminate the occurrence of powerful temperature changes - this not only creates discomfort, but can also provoke health problems. It is impossible to completely eliminate differences in the temperature of the flows; it is only necessary to limit their magnitude. Normal ventilation systems are formed during the construction of the bathhouse, while channels are made and openings are prepared. Windows are installed only after the decorative cladding of the building has been completed. Therefore, you will have to enter information about the design of ventilation ducts into the bathhouse design.

In most cases, ventilation openings are made strictly the same. The outlet hole can be made larger than the inlet hole, but according to safety rules it cannot be smaller than the first one. For the same reasons, they sometimes resort to paired exit windows. It is worth using valves rather than doors as control elements; when closed, it is impossible to maintain the gaps. When the steam room warms up for the first time, the valves are closed 100% until the air reaches the desired temperature.

The use of elements with controlled position is also useful because the amount of air flow must be adjusted according to the season. When they stand on the street negative temperatures, even a very small stream of air brings a lot of cold. Therefore, you should not open the ventilation windows completely. The cross sections of such windows should average 24 square meters. cm per 1 cu. m of internal volume. But these are only preliminary figures, and if you doubt the result obtained, you should contact qualified heating engineers for calculations.

It is strictly forbidden to place ventilation windows at the same height or even directly opposite each other, since this will not allow all the air in the bath to be warmed up sufficiently. In addition, such a design will not allow air masses to mix evenly, which means that it will be necessary to carefully calculate the accuracy of the location of the ventilation elements. It is recommended to place exhaust windows just below the ceiling, because the air immediately rushes upward after heating.

Types of ventilation systems

The ventilation device in the bathhouse varies according to the design of the room and its total volume. Natural ventilation is based on the difference in temperatures and pressures inside and outside. In order for it to work efficiently, air input is organized near the stove, at a level of 25-35 cm from the floor. The exit hole is made on opposite walls approximately 15-25 cm below the ceiling. But it is important to take into account that this scheme is not good enough for steam rooms, since it is relatively cold down there, and always hot at the top.

Natural air movement in similar situation too difficult to organize, you will have to very carefully and carefully arrange the components of the ventilation system. A forced circuit does not always require the use of electronic control systems, with complex panels and so on. There are simpler options when ventilation windows, placed in a special way, are complemented by an exhaust fan. The combination of such components is especially effective when the bathhouse is located inside the house, the windows are not placed inside the outer wall, but are connected to the exits by a long box for ventilation. Duct fans need to be selected very carefully, because the conditions of their operation in baths differ from normal parameters.

The peculiarity of such devices is the increased waterproofing of electrical circuits and main mechanical parts, their adaptation to operation in high temperature without consequences for technology. State supply ventilation and its arrangement in each room is adapted to individual characteristics and the type of bathhouse. It follows that the time spent on calculations and thinking through the project is not wasted - it will save a lot of money and time, and get the optimal result sooner.

As is already known, the majority of projects involve the location of introductory windows near the stoves at 0.25-0.35 m from the floor. With this design, the stove transfers heat to air coming from outside, and a flow appears moving in the direction of the hood. Having covered the entire distance, the hot and street flows ultimately cover the entire volume of the steam room, and the area where the top shelf is located is heated the most.

In the second option, by installing an exhaust fan, you can mount the inlet and outlet openings on the same wall. The air flow is directed first in the direction of the heating device. Having received a thermal impulse, it begins to rise to the ceiling and moves in a wide arc that covers the entire room. This approach will be effective if the bathhouse is built into the house and has only one external wall, and there is no need to install a ventilation duct.

If a bathhouse with a leaky floor is created, the introductory window is placed in the same place as in the first case, directly next to the stove. When the heated air gives off heat in the upper part of the steam room, it cools and sinks to the floor, leaving through the holes in the flooring. This technique improves the evaporation of water accumulating below and allows you to delay the failure of the wooden floor. The hood is placed either in the next room or in isolated channels that do not allow air to return to the steam room. The complexity of the flow path makes the use of a fan mandatory. This option is used very rarely, since it is not easy to calculate everything accurately and provide details properly.

Another type involves a continuously operating furnace, the vent of which replaces the hood. For inflow, a window is made under the shelf opposite the stove itself and at the same level. Cold air displaces the heated mass upward, and when the parts of the flow that have given up heat descend, they go into the ash channel. There are even more complex systems when a pair of inlet and a pair of outlet ventilation windows are placed (necessarily with a forced circulation type). It is quite difficult to regulate complex complexes, but their effectiveness is higher than in simple cases.

The Bastu system is the placement of inlet openings(with adjustable valves) behind or under the stove. The organization of vents under the stove is not necessary, although it is highly desirable. Through these openings, air enters the room from the underground part of the bathhouse, which is connected to the outside atmosphere by the foundation vents. When a bathhouse is made in a previously prepared room, you need to choose a room with a couple external walls; when preparing the basement, choose an angle that meets the same requirements. The dimensions of the inlet and outlet openings are calculated according to general rules.

How to do it right?

Installation of ventilation implies that when the pipe is brought out, it is protected from the penetration of snow, dirt, rain and melt water. When this cannot be done, you can arrange a ventilation box or direct the pipe upward, passing it through the ceiling and roof. In the latter case, the channel is covered with an umbrella to prevent the same precipitation and falling leaves from penetrating inside. Providing high-level ventilation means ventilating and drying all rooms, structural parts of walls, floors, attics and under-roof spaces.

Step by step guide installation of ventilation in a bathhouse is not difficult to find, however, the simplest option is to use asbestos-cement pipes and gratings, selected according to the diameter of the channel. If we talk about technical performance, the most effective and convenient design in frame-type walls is the use of supply valves. First, the valve is disassembled and drawn on the wall with a circle marker where the future ventilation ducts will go. To make holes in the casing, use a drill, and take large-diameter drills into which a jigsaw knife can easily fit.

using the jigsaw itself, cut out a circle;
remove wooden parts;
remove insulation and vapor barrier material;
using a long drill, pierce the outer casing (this must be done to avoid mistakes when placing the outer lobe of the valve);
mark a suitable hole outside and make it using long drills;
saw off the valve tubes according to the thickness of the wall.

Then you need to mount the tube in the hole with your own hands and secure the inner segment of the valve with self-tapping screws, only after which you can install the outer part of the product. Installation of valves is recommended in the washing compartment and in the dressing room.

When preparing a new building, it is imperative to calculate both the size of the holes and the required fan power. Ventilation can be adjusted even if it was not done initially. A common mistake is to rely on burst ventilation and the use of stove drafts to dry the air. In principle, this scheme works, but it has serious drawbacks. So, when windows and doors are opened, instead of lowering the temperature, steam is released into adjacent rooms.

It does not go outside, but turns into condensation. The air heating decreases only for a short time, and very soon the bathhouse becomes uncomfortable again. To take advantage of the effect of stove drafts for ventilation, holes are needed, but they should only be made at the bottom. This will ensure air flow from neighboring rooms, where fresh portions will be supplied from the outside. The damper and doors of the furnace itself help regulate ventilation; to increase the inflow, they are opened to the limit, and to weaken, they are partially closed (to avoid the entry of carbon monoxide).

A simple calculation can only be made for forced ventilation, and the natural air flow is much more complex and is subject to a number of different factors. Among them, special attention should be paid to the strength and direction of the wind that blows in a particular area. If the outlet is located on the side from which strong winds are directed, this may lead to the flow of influent mass into it (the so-called effect reverse thrust or its overturning).

Prevention of such a negative phenomenon seems simple - it is lengthening the channels leading in the right direction or using turns in them. But each turn complicates the work and reduces the speed of air exit or entry. The solution would be to orient the inlet to the side from which the wind mainly blows, while placing the outlet on the opposite side or on the roof (with a high pipe).

Use the ventilation duct in block wall not worth it, in such cases it is mounted on the internal wall and partition. According to experts, the best air duct is the one built from galvanized pipes. Plastic structures can be installed with caution, carefully assessing their permissible temperature range. The gap from the pipe to the walls of the hole is filled with mineral wool or more modern insulation materials. Polyurethane foam helps eliminate gaps at the inlet and outlet.

The method of fastening ventilation grilles is selected according to the material that serves as the base. Checking the quality of ventilation is very easy - bring a fire or a smoking object to the hole. This will allow you to further find out at what speed the air is moving. Most often, only a hood, supplemented by a fan, is placed in the dressing room.

When the furnace firebox is brought into the dressing room, you need to make a special ventilation channel based on galvanized steel, passed under finished floors and supplying air directly to the oven door. The channel must be created before the finished floor is laid. One edge of the pipe is inserted into the hole and fixed in it polyurethane foam, is clogged with a grate. An adjustable plug is installed on the edge approaching the stove.

Good ventilation is one that avoids condensation on the ceiling surface. As for the subfloor, work on it begins with the preparation of a cement screed, which is tilted towards the drain pipe. The foundation is equipped with a pair of holes (in opposite walls, but not directly opposite each other). Air flows should flow under the floor along the most intricate trajectories. The holes are sealed with valves, which will allow you to adjust the rate of movement of the jet according to the current season.

In a bathhouse, which was originally built without floor ventilation, it is necessary to drill concrete base down to the ground. This will turn out to be a decent replacement for full-fledged drainage when there is no desire to work on installing drain pipes. The ventilated floor must be decorated with lintels, which are pipes or wooden beams with a cross-section of 11x6 or 15x8 cm. The logs are covered with treated and well-polished oak boards.

How to choose?

In a Russian bath, unlike an ordinary washing room, It is necessary to ensure the following conditions using ventilation:

temperature in the steam room – from 50 to 60 degrees;
relative humidity – not lower than 70 and not higher than 90%;
very fast drying any wooden surface after finishing washing;
prompt reduction of humidity while eliminating drafts and opening doors;
the same air quality in the steam room, as well as in the relaxation room, regardless of the season;
preservation of all traditional properties of the Russian bath.

No ventilation devices will help save you from carbon monoxide, if there is a constant influx of it. You will have to continuously monitor the complete combustion of the wood, and only after all the coals have died out, shut off the chimney. The organization of air flow in a log bathhouse occurs through the crowns of the walls.

For obvious reasons, this approach is not suitable for a brick building. When walls are sheathed with boards or clapboards, it is imperative to use ventilation holes, otherwise the negative effect of dampness will be excessively strong. In most cases, a hole of 200x200 mm will be sufficient to lead pipes to the street. The choice of plastic or metal should be made in accordance with specific project and operating conditions of the ventilation system.

A bathhouse made of foam blocks must be ventilated inside the walls. The layers of waterproofing and sheathing are separated ventilation gap, for external cladding it is 40-50 mm, and inside the bath - 30-40 mm. A typical design involves the use of lathing, which already helps to hold the wall cladding in place. In addition to in-wall ventilation, all rooms are equipped with an air intake at the bottom (usually behind the stoves) and an outlet (near the ceiling). The advantage of an active air freshening system is that it can be placed anywhere.

In most cases, foam block baths are ventilated in one burst, that is, by simultaneously opening the front door and the window farthest from it. Only a professional calculation is guaranteed to allow you to find out whether you need artificial ventilation or natural circulation of air masses will suffice.

Components and materials

A fan heater for a bath must have a certain level of thermal protection (not lower than IP44); its body is always made of heat-resistant materials. Modern devices have very high power and operate almost silently, the volume is no more than 35 dB.

The following can be used as ventilation holes in attics:

special windows;
aerators;
soffits.

A high-quality ventilation system is an essential element of a steam room. The absence or improper organization of ventilation in the bathhouse is dangerous to human health. A properly equipped system will protect people from carbon monoxide and improve the comfort of staying indoors. We will talk further about the features and technology of installing a ventilation system in a bathhouse.

Characteristics of proper ventilation for a steam room

Proper ventilation in a bathhouse performs several functions at once:

provides the room with oxygen;
improves the comfort of staying in the steam room;
removes carbon monoxide;
allows for economically efficient use of firewood;
distributes air flow evenly;
protects the building from the formation of mold or mildew.

The most optimal ventilation option in a bathhouse is supply and exhaust. For these purposes, arrange:

supply opening - through them an influx of fresh air is organized into the steam room, a fan with a ventilation tube is installed, additional air flow is provided by open vents or through the door;
exhaust hole - removal of heated air from the room, through a firebox, blower or devices that improve draft.

To improve the supply and exhaust ventilation system, various methods are used. We invite you to familiarize yourself with one of the most effective ventilation systems:

1. The supply openings are located at the bottom of the room, next to the firebox.

2. Exhaust holes are strictly on the opposite side from above. It is possible to organize two holes at once for better air control.

3. The height of the exhaust opening determines the level of draft. If the ventilation opening is low, further strengthen the system with a ventilation pipe.

4. Using special dampers, the air supply from the room is controlled.

5. The air in the steam room is renewed every 2-3 hours.

How to make ventilation in a steam room with a separate firebox

no trash in the steam room;
the door to the room opens only upon entry;
possibility of installing heat-resistant glass for admiring an open flame.

To install supply openings in a room, two methods are used:

1. Arrangement of a ventilation duct in the underground space. Bringing it out in front of the furnace room, installing ventilation grilles on the duct.

2. Floor ventilation supply.

Install the hood on the opposite wall, diagonally in relation to the supply opening.

The main quality of organizing proper ventilation is that the supply openings must coincide in area with the exhaust openings.

Ventilation diagram in a steam room with an indoor firebox

1. Build a special brick podium on which the stove is installed. With its help, a ventilation duct is connected to the stove.

2. Lay the ends, build another box of bricks. As a result, the first structure was installed at the top of the stove channel, and the second - to the steam room door.

3. On the wall adjacent to the regular room, build doors where the masonry passes through. They warm up the next room, if necessary.

4. A stove is installed on the podium; it can be mounted on a corner or on steel pictures. Finish the oven with brick, install a brick screen with two convection valves.

5. The exhaust ventilation system operates due to the furnace firebox.

Correct installation of the ventilation system is based on its correct adjustment. General rules for controlling the ventilation system:

at the beginning of the furnace fire, all openings, both supply and exhaust, are closed;
wait until the temperature increases, then adjust the ventilation holes with the valves;
if it is necessary to increase the volume of oxygen in the room, open the inlet;
Upon completion of work, open the doors for better ventilation of the steam room.

Steam room ventilation photo:

To determine the temperature and humidity in the room, use special instruments. An alcohol or electric thermometer will help measure the temperature. Please note that the use of the mercury version is strictly prohibited. Use a hygrometer to determine the humidity level.

The operating principle of the ventilation system is based on the following factors:

by heating the oven, the air gradually heats up and exits through the convection door;
the bottom door remains open until the oven is completely warmed up;
close the door from below and work with the top hatch;
during the vaping process, only the blower installed on the box opens;
After using the steam room for its intended purpose, ventilate the room well.

Do-it-yourself ventilation device in the steam room

The main functions of the ventilation system in the bathhouse:

air supply during bath procedures;
high-quality room drying.

The ventilation system in the bathhouse should not:

violate the temperature of the room while taking bath procedures;
separate temperature flows, that is, cool air is closer to the floor, and warm air is on top;
remove unexhausted air from the steam room.

In addition, the lack of ventilation leads to the appearance of unpleasant air in the room, the formation of mold and mildew, which are harmful to human health.

Let us highlight three main types of ventilation in the steam room:

a natural option is to supply air flows through a pressure difference;
mechanical option - air supply using special mechanisms, when measuring these characteristics with instruments;
a combined option - creating artificial pressure with fans and hoods.

There are two types of air transportation in a room: supply and exhaust. For these purposes, equip a hole located diagonally with respect to the inlet.

In addition, provide a ventilated floor in the bathhouse. Thus, the life of the floor covering increases, since it is in constant contact with water. Recommendations for arranging floor ventilation:

1. During the installation of the foundation base, ensure ventilation of the floors and build vents from the basement.

2. Build ventilation holes on opposite walls to ensure air flow. Install grilles on them to prevent rodents from entering.

3. The finished floor should be slightly higher in level than the ash pit is located. Thus, it will function as a hood.

4. Install wooden boards with a small gap, at least half a centimeter.

5. After taking bath procedures, ventilate the room well and dry the floors.

DIY methods for organizing ventilation in a steam room

We offer five of the most popular schemes for organizing supply ventilation in a steam room:

1. Scheme No. 1.

Install the inlet under the stove 50 cm from the floor, and the outlet on the opposite side, thirty centimeters from the ceiling. Forced movement of air masses is provided by a fan. Thus, it is possible to ensure uniform heating of the air. The height of the first hole regulates the draft force of natural ventilation.

2. Scheme No. 2.

Two ventilation holes are located on one wall, always opposite the stove. The inlet is installed at a distance of thirty centimeters from the floor, and the outlet - thirty centimeters from the ceiling. Install a fan in the outlet, the cooled air entering the room collides with the stove, heats up and goes outside.

3. Scheme No. 3.

4. Scheme No. 4.

This method is relevant for a steam room with a floor that has holes for water drainage. The inlet is installed behind the stove, and the outlet is a drain pipe through which the air is discharged outside.

5. Scheme No. 5.

Relevant for a bathhouse with a constantly running stove. The inlet is installed opposite the stove, and the ash pit with a chimney serves as an outlet

How to make a vapor barrier for a steam room with your own hands

Vapor barrier in the steam room allows you to maintain the optimal room temperature. Special materials in the form of vapor-proof films, insulation and waterproofing will help create high-quality vapor barrier. The film protects the insulation from the penetration of water vapor, while not allowing moisture in the hot air to pass through.

A well-equipped vapor barrier and ventilation system increases the service life of the room itself and its external decoration. Since hot air rises upward, first of all, properly vapor barrier the ceiling.

In addition, edged boards will help to vapor barrier the ceiling. Cardboard impregnated with drying oil is installed on the boards, which is then lined with wooden clapboard.

Expanded polystyrene boards are a modern replacement for soft clay and have good thermal insulation and performance characteristics.

The following are used as vapor barrier materials for steam room walls:

roofing felt;
aluminum foil;
glassine;
polyethylene based film.

excellent resistance to moisture;
resistance to increased temperature;
laminated coating prevents the development of mold and mildew;
combined thermal vapor barrier.

In addition, it is possible to use rolled vapor barrier in the form of rolled foil or fiberglass boards. To seal joints between vapor barrier materials, use foil tape.

High-quality ventilation is one of the most important components of a good bath

In order to accurately determine the parameters of the project, it is necessary to clarify its intended purpose. Creation for a bathhouse allows you to solve the following practical problems:

a supply of fresh air is ensured;
combustion products, carbon dioxide, and other harmful substances are removed;
The destructive processes of rotting and corrosion are prevented.

Of course, the operation of this system should not worsen other consumer characteristics of the building. For example, if the supply of cold air is excessive, the cost of maintaining a high temperature will increase.

This list of actions will help you figure out how to do ventilation so as not to miss important points:

Find out how to organize ventilation in different rooms buildings.
It is necessary to take into account the combined influence of ventilation and heating, the characteristics of wall materials and other characteristics of the building.
You should find out which components and finished products are useful for creating an effective modern ventilation system.

How does high-quality ventilation work in a bathhouse: diagram and design, features of different rooms

For electrical wiring, use an appropriate cable that provides reliable insulation even when immersed in liquid. The switch is installed in the rest room, or in another room with normal level humidity.

For ventilation in the bathhouse sink, you can use a small window or a special channel. In any case, you need to configure the system in such a way as to eliminate drafts. You can combine the air supply parts here and in the steam room to increase the air temperature and ensure ventilation of wooden floor coverings.

Ventilation design in the dressing room

In this room, the organization of access to fresh air does not differ from a similar system in a regular living room. Natural and forced ventilation are available in various combinations. We must remember that hypothermia provokes the occurrence of colds and other diseases.

For your information! Log houses have special abilities. They create comfortable temperature conditions in rooms without special technical means due to natural micro-ventilation of the walls. For intensive ventilation, you can open doors and windows.

How to properly ventilate a bathhouse: differences between buildings made of different materials

This section examines in detail architectural features buildings. Proper ventilation in the bath should not have a negative impact on structural parts. Moreover, it creates favorable conditions to extend service life without overhaul. In order to avoid mistakes and unnecessary actions, the appropriate system must be created at the design stage. An example with a concrete foundation explains the convenience of installing holes using embedded parts. Drilling them in a frozen block will be accompanied by significant difficulties.

Frame construction

The gaps between the frame elements are filled with mineral wool. It is covered with a polymer film to prevent moisture from entering. Outside - install lining, paint, and other finishing coatings.

Such a design can be created quickly, with minimal costs. A light structure does not require a strong foundation. The multilayer wall structure has low thermal conductivity, which reduces operating costs. In order not to break their tightness, ventilation channels in the frame bath are installed in advance, along with installation power elements designs.

For your information! If you use slabs of polyurethane foam, the cost of the project will increase slightly. But in this case no special precautions are needed. The insulating properties of these materials do not deteriorate in conditions of high humidity.

Nuances that are taken into account when equipping a log house

To correctly determine the ventilation parameters in a wooden bath, the following features must be taken into account:

Buildings made from these materials have natural ventilation. But its performance is not enough for a bath.
Supply and exhaust system created in such a way as to ensure rapid removal of moisture after completion of a session of wellness procedures.
If forced ventilation is selected, electrical wiring will be installed taking into account the proximity of flammable materials. The rules of specialized regulations must be strictly followed.
Treatment with anti-rotting agents and others chemicals carry out carefully to prevent them from entering the indoor atmosphere. It is advisable not to use potential hazardous substances for creating decorative and protective coatings in washing and steam rooms.

For your information! Such buildings are installed on strip foundation. The base of the floor is made of concrete. Holes are created in these elements at the stage of pouring the solution.

Correct installation of ventilation in a brick house

Structures made from these materials are highly resistant to various external influences. They can withstand heavy loads without damage. They are not destroyed by changes in temperature and humidity, harmful insects and microorganisms. In the absence of flammability, no special measures are required when installing power supply routes.

In order to avoid such heavy operations, the necessary passes are made during the laying process. To ensure the work is carried out accurately, marks are made in the design documentation. At the project preparation stage, the parameters and installation lines of electrical networks are determined.

Application of bastu for a bath: diagram, operation

This technology has been used in Sweden for hundreds of years. It provides effective ventilation of rooms without electric drives. Additional benefit is economical consumption of thermal energy.

The figure shows a system for two rooms. In the steam room, air is supplied to the space under the stove. Using a special casing, the basic principle of the technology is implemented: “inverted glass”. A heated air stream under pressure enters the rooms. Output paths - as in standard version, through a box, with a fence from the lower parts of the rooms. The use of bastu ventilation in a Russian bath will allow you to quickly dry the floors. Pay attention to the separate inlet installed in the rest room. With the help of a dosed supply of cold/warm air, you can maintain comfortable temperature conditions at any time of the year.

When choosing suitable products, the climatic conditions in the region are taken into account. For northern regions, triple glazed windows with good insulating characteristics are installed. If you purchase plastic frames, you need to check the number of cameras.

To eliminate fogging, you can use the data from the following table. The values in it correspond to the temperature outside, at which inside droplets of moisture condense on glass:

Room temperature, °C	Humidity, %
	20	30	40	60	80	100
0	-20	-15	-12	-6,9	-3,1	0
5	-15,8	-11	-7,5	-2,2	1,8	4,8
10	-11,8	-6,8	-2,8	2,7	6,8	10,1
15	-7,6	-2,5	-1,4	7,4	11,7	15,8
20	-3,7	1,8	5,9	11,8	16,3	20,1
25	-0,4	6,1	10,4	16,6	21,2	24,8

When choosing an installation location, enter the dimensions of the block in the opening with the following gaps:

bottom: from 40 to 60 mm;
top: from 15 to 25 mm;
on the sides: from 15 to 25 mm.

It is necessary to take into account a significant change in the size of the opening in a wooden structure. To prevent damage to the frame, special damping elements are installed. In brick buildings such precautions will not be necessary. The doors should open freely. If necessary, other curtains are installed from the inside.

For your information! To avoid damage by high temperatures and to prevent deterioration of the atmosphere, windows are not installed in the steam room.

Parameters of a suitable fan

A forced system is installed for large premises. It will be needed in a building made of brick or other materials that do not allow air to pass through.

When choosing a fan for a bath, check the following parameters:

To calculate productivity, multiply by 5. A reserve (20-40%) is added taking into account the characteristics of a particular room.
The housings and impellers of high-quality specialized equipment are made from polymers (composite materials) that are resistant to high temperatures and ultraviolet radiation.
Rubber gaskets reduce noise and the negative impact of vibrations on the integrity of the structure.
The shaft is mounted on durable ball bearings, which perform their functions fully without lubrication or other routine procedures.
All electrical components are reliably protected from moisture.
When equipped, air movement in the opposite direction is prevented when the equipment is turned off.

The video below explains the DIY fan installation process. These instructions can be used for installing equipment in a bathhouse, bathroom, or toilet.

Types of valves for ventilation ducts

A non-return ventilation valve for a bathhouse does not let cold air in from the outside. Similar phenomena can occur, for example, in strong winds. The figure shows that the damper is moved by a counterweight. There are no electric drives or other complex components, which explains the relatively low cost.

Valves are selected taking into account different needs:

The corresponding modifications are designed for vertical or horizontal installation.
They produce special products for round and square air ducts.
To increase resistance to corrosion processes, metal valves are coated with a layer of zinc.
Some models are designed specifically for collaboration with fan.

Installing a vent in a bathhouse

The optimal path for air movement helps to correctly determine the installation parameters of the inlet and outlet openings. If the vents in the bath are installed at the same level, the required uniform heating effect will not be obtained. The flow will be directed along the shortest path, creating a draft. It is also recommended to consider the following points when planning:
