Vacation home It’s impossible to imagine without a fireplace or stove, which means that there will definitely be a chimney on the roof. The device for removing combustion products, known since ancient times, is a complex engineering design. For the safe and successful functioning of the chimney duct in the house, first of all, you need to responsibly design the pipe, properly make the chimney with your own hands, and then periodically check its operation and clean it.

Chimney design

Chimneys are designed in such a way as to effectively remove combustion products from the room. The main part of the structure is a straight vertical channel. The smoke exhaust starts directly from the boiler. After the vertical part of the pipe, the channel passes through cutting and covering, which leads to the attic, and then enters the bed, turning 90 degrees. Another bed ends vertical pipe, which is located above the ridge of the roof.

Due to changes in temperature and pressure in the chimney, a constant movement of air is formed in the “bottom to top” direction, which is called draft. The presence of traction is the main factor for proper operation chimney. The smoke exhaust pipe must have good aerodynamic characteristics, therefore preference is given to designs with round. In pipes with smooth walls, smoke rises freely to the top without forming turbulence. To prevent condensation, it is customary to insulate the outer parts of the pipe.

Choosing material for the chimney

When deciding which chimney to install, you will have to focus on the stove: you need to know the type heating device, flue gas temperature, location, efficiency. The exhaust gases become very hot during the operation of devices that operate on solid fuel, because the temperature of the smoke during its incomplete combustion can easily reach up to 600 degrees Celsius.

Since brick can withstand such high heat, until recently, brick chimneys were the most popular. This type is still relevant today for house stoves and classic types of masonry fireplaces. Also, ceramics, heat-resistant and enameled steel tolerate temperature loads well.

New generation of heat generators natural gas or liquid fuel has a high efficiency, which reaches 90%, due to the low temperature of the combustion product (less than 160 degrees). However, in this case, aggressively acidic condensate appears on the walls of the chimney, which quickly destroys the porous material - asbestos cement and brick. This process can be prevented with the help of additional waterproofing. But it’s easier to make a chimney from fireclay, steel, polymer materials, special types of glass and ceramics.

Smooth mirror surface and easy installation are the main features positive traits modern chimneys made of steel. The shiny surface ensures minimal friction of the exhaust gas against the walls of the chimney, and the collectors included in the kit modular systems, condensate is removed outside the chimney. If the house has a brick shaft, then a steel channel can be laid inside it.

Ardent fans style solution“High-tech” can install special reflective screens. The wall inside the room along which the chimney is located can be lined with a patterned ceramic tiles. A outer part smoke exhaust pipes can be covered with galvanized iron, which is painted in any color you like.

How to make a high-quality chimney

An efficient, high-quality and reliable chimney is the key to the absence of smoke and good reverse thrust, and also acts as an important element of the cottage comfort system. The best option in terms of price/quality, a chimney a la “sandwich” is recognized - a heat-insulated channel with an impressive service life, low soot deposition and reduced level condensation formation.

Calculation of the main characteristics of the chimney - diameter and draft force is carried out in compliance with the main requirement: draft must simultaneously increase with increasing pipe height. Otherwise, the effect of a chimney “choked” with smoke will occur in the form of a decrease in draft with increasing height and a large cross-section of the pipe. IN last resort are being considered appearance and harmonious proportions of the chimney with other elements of the building - roof ridge, chimney height, ventilation ducts. First of all, the efficiency of the heating system and its functionality.

Options design smoke exhaust channels depend on the installation location of the boiler and the characteristics of the room. The internal chimney is usually installed inside the building and carried out together with additional work: arrangement of support, grooves and protective casing. It is not necessary to insulate the internal chimney. But no less than 60 centimeters before the ceiling you need to install sandwich-type insulation. According to building regulations It is strictly forbidden to lay through the ceilings of uninsulated channels. Moreover, pipes that pass through unheated attics must be insulated.

The external attached smoke exhaust duct consists of a connecting flue, sections, an inspection and a load-bearing wall bracket. For an external chimney, it is necessary to insulate the pipes. An ordinary cylinder is the most effective form chimney, ensuring easy operation of the product. When choosing the shape of a chimney, experts recommend choosing the most simple circuits, because intricate shapes are the main reason for the accumulation of large amounts of soot. The height of the installed chimney duct should not be less than 5 meters.

When installing a chimney, it is necessary to ensure that all joints of the structure are located below or above the interfloor lintels and are open for visual inspection. Before installing a chimney on your own, you should study fire safety standards and insulate joints with non-combustible materials, as well as Special attention pay attention to the exit point to the roof of the “sandwich”.

Chimney installation

The process of installing a chimney is usually carried out in the “bottom-up” direction, in other words, starting from the heating object. The pipe links must be assembled sequentially: each subsequent section is inserted into the previous link. This DIY chimney installation sequence protects the product from moisture getting into the insulation. With the aim of better protection structures against moisture, it is recommended to use a special sealant that has operating temperature about 1000 degrees.

All working joints in the heating system must be fixed using special clamps and brackets must be installed along the laying line in increments of 1.5-2 meters, which are used to fasten the structure to the building elements. It is imperative to monitor horizontally laid areas and avoid contact with various communications - gas pipes and electrical wiring, as well as limit the length of each section to one meter.

To make it easier to clean the chimney during operation, install a door or a removable part at the bottom of the structure. Working channels must be installed along internal partitions and walls, structures must be made exclusively of non-combustible material. If it is impossible for technical reasons to install along the walls, it is necessary to use mounted chimneys.

High-quality chimney insulation is the key to quickly warming up the room and the formation of a small amount of condensation. By placing pipes near flammable finishes, additional fire protection It is the insulation that acts. The part of the chimney pipe facing the street should be protected from the wind and fixed. Protection from debris and precipitation is provided by deflectors, weather vanes and nets. But such protection is not suitable in all cases. If a hood is the norm for stoves and fireplaces, then for gas equipment constitutes a severe violation of system security.

Caring for a chimney made by yourself is not too burdensome. It costs only a few times a year to organize it (at the end and at the beginning heating season) check the quality of traction in it, as well as the tightness of the seams and the integrity of the joints of its individual elements. When carrying out such inspections, it is possible to carry out cleaning at the same time. inner surface smoke exhaust from soot.

Brick chimney laying

Laying a brick chimney is considered a difficult job, so you must watch a video about a do-it-yourself chimney. But if the brick channel runs inside the wall, then no special qualifications are required to organize it. It is enough to leave in the carrier brick wall an unfilled shaft, the cross-section of which is equal to the size of the lying brick.

The sides of the brick are approximately 25 by 12 centimeters. According to building codes, for 1 kW of installed boiler power there should be about 8 square centimeters of the chimney cross-sectional area. Taking into account the area of ​​the larger side of a standard brick, the result is 300 square centimeters. Boilers with a power of up to 38 kW can be connected to a smoke exhaust duct with a similar cross-section, which is suitable for heating houses with an area of ​​up to 350 square meters.

If you plan to post it separately brick structure, then its construction must be approached carefully. In this case, the masonry of the chimney requires more careful execution - the corners must be straight and the walls smooth. If the chimney is not adjacent to the wall, then it should be made strictly vertical. The channel that is adjacent to the wall should be attached to vertical surface using anchors located every 4-5 rows. It is recommended to provide technological and inspection holes in the masonry, and also to place a hatch in the lower part of the shaft for removing soot.

Chimney walls with inside should be smooth. There are many recommendations for decorating the surface of a smoke shaft - one option suggests plastering the channel from the inside “under the mitten”. In this way, the cross-section of the channel is brought closer to a round shape, and irregularities are also smoothed out. Another option does not require coating, because if the work is done poorly, pieces of plaster fall into the channel and impede the movement of air. It is customary to line the outer part of the chimney facing bricks or decorate with roofing material.

Chimney cleaning

The combustion of any fuel is accompanied by the release of carbon compounds and carbon dioxide. When gas burns, fewer combustion products are released, and when it is burned solid fuel - a large number of. Substances that contain carbon settle on the walls of the chimney in the form of soot, which must be periodically removed from the chimney.

They clean and repair the chimney with their own hands using chemical, mechanical and physical methods. For chemical treatment, products are used that contain substances that corrode soot. The most in a simple way is the burning of aspen logs in a stove or fireplace, the combustion temperature of which is about 1100 degrees Celsius. Soot burns at this temperature, but this method is dangerous, and it can be practiced if the smoke channel is not damaged and is made of fire-resistant materials.

If the chimney has not been cleaned for a long time, and the layer of soot on its walls exceeds 3 millimeters, then preliminary cleaning should be carried out. mechanical cleaning. For this purpose, a weight on a rope with a ruff has been used for a long time, which is thrown from above into the chimney. He pushes the plug down. If this manipulation does not bring results, then there is nothing left to do but dismantle that part of the chimney channel in which the blockage has formed.

Specialists carry out professional cleaning using reagents and sprays, after treatment with which the soot is separated from the walls of the chimney and falls into the firebox. The effect of this procedure lasts for 3-4 months. You can also clean the chimney using a special vacuum cleaner, which sucks out soot from the duct through the firebox. But this does not help with large ash deposits.

Now you know what an ideal chimney should be in terms of functionality, efficiency and safety. Follow the instructions carefully before making a chimney with your own hands, and your home’s heating system will work for decades.

In new private houses equipped heating boilers, for withdrawal flue gases install traditional brick chimneys, and also increasingly used chimney systems made of steel or ceramics.

Which chimney should you choose? How to properly make a chimney for a boiler in a private house? Where can I buy quality chimney pipes of steel?

For a solid fuel boiler - a brick chimney

A brick chimney is usually costs less, than modern chimney systems. Traditional trumpet chimney from ceramic bricks easily withstands high flue gas temperatures. The pipe can even withstand ignition of soot accumulations in the chimney.

A brick chimney for a boiler in a private house is a rather heavy structure. The chimney is located on the foundation or durable reinforced concrete floor. The construction of such a chimney requires certain skills; it is better to entrust the laying of a sealed and durable chimney to a qualified stove mason.

Channels and chimneys and ventilation are often placed in a brick chimney

The chimney is laid from high-quality solid ceramic bricks of a grade not lower than M125 on a regular masonry mortar. The upper section of the pipe, above the roof, can be laid out from the front or clinker bricks. The thickness of the chimney walls must be at least 120 mm(half a brick).

Brick chimney laying. Ventilation ducts are usually placed next to the chimney in one vertical block. Templates make it easier to lay even channels with smooth walls.

The size of the chimney and ventilation channels is chosen as a multiple of the brick size, taking into account the thickness of the vertical joints. For example, channel cross-section can be 140x140 mm(1/2x1/2 brick) or 140x200 mm(1/2x3/4 bricks), or 140x270 mm(1/2 x 1 brick). In practice, a smoke channel is often made measuring 20 x 20 cm(3/4x3/4 bricks). If necessary, it is easy to select and insert a round steel or ceramic liner of the appropriate diameter into such a channel.

The flue gases in the chimney duct should not be very cool. Therefore, they try to build the chimney into the masonry interior wall at home or attached to the wall. Sections of the chimney that pass through unheated room(attic) or outside the house insulated with mineral wool.

Brick the chimney serves reliably and for a long time only at high flue gas temperatures, which prevents condensation from forming in the pipe. As a rule, this condition is met when the chimney is operated with a conventional one.

When working with modern boilers on gas or liquid fuel, as well as with solid fuel pyrolysis boilers, pellet and others, operating for a long time in a slow burning mode of low intensity, a brick chimney is destroyed quite quickly.

Modern boilers are designed in such a way that the exhaust gases have a fairly low temperature. As a result, condensation of water vapor contained in the flue gases occurs in the chimney. The pipe walls are constantly moistened. In addition, combining with other combustion products, water forms aggressive chemical compounds on the inner surface of the pipe.

In particular, the exhaust gases of boilers contain sulfur, which, interacting with water, forms sulfuric acid in the chimney, which corrodes its walls. External signs destruction - dark wet spots on outer surface brick pipe.

The operating mode of a solid fuel pyrolysis boiler also contributes to the formation of aggressive condensate in the chimney, which quickly destroys the brick chimney.

Rough chimney walls contribute to the accumulation of solid soot particles on them. Wall roughness and rectangular shape the chimney channel makes it difficult to clean the chimney from deposits.

For connecting gas and other boilers with low flue gas temperatures to a brick chimney, in a brick channel it is necessary to place an insert - a steel or ceramic chimney pipe.

A chimney made of ceramic pipes is a universal solution for a boiler in a private house

Chimneys made of special ceramic chimney pipes can be used for all types of boilers. The material is resistant to high temperatures and to any aggressive chemical compounds that may form in the chimney during combustion different types fuel. This type of chimney is the most durable.

Ceramic chimney pipes are classified according to their permissible maximum temperature waste gases.

The chimney in a private house is most often built invisible to the eye. This can be done even at the planning stage of building a house. If there are several chimneys in the house, then they are combined into one or two devices.

Device steel chimney in a private house

The design of the chimney depends on functional features devices for which they are intended. The complexity and configuration of the chimney depends on their location and power.

Types of chimneys:

• ventilation,
• gas outlets,
• smoke

Ventilation systems

Main function ventilation pipes is that they help remove polluted air masses from the room.

Originally made brick ventilation chimney

Ventilation ducts must be in those places where the room is least ventilated. It is especially important to place such pipes in the kitchen area, bathroom, and toilet.

Gas exhaust systems

Gas exhaust chimney pipes are used if the house uses gas system heating. They remove combustion products outside the room, and thus ensure the safety of using the heating system. Pipes must be able to withstand a variety of influences harmful substances. As soon as combustion products enter the chimney, they immediately react with the moisture that is already in the pipe. As a result of this, an oxidation process occurs, which can cause destruction or internal deformation of the pipe. Also, such a chimney helps to increase draft.

Diagram of the device and design of the flue pipe of the chimney

Smoke pipes

Chimneys are used when installed in a house heating equipment, which works on solid fuel– these can be stoves or fireplaces. There are most of them in the house, which is why they are often combined into one or more.

device diagram and design of a brick chimney

Chimney pipes

The chimney device is quite simple, it involves the use of special pipes, through which polluted air or combustion products are removed from the premises.

Pipes are:

• brick,
• metal,
• ceramic,
• polymer.

Distinctive features of a brick chimney

Despite the fact that today there is a very large number of materials that can be used to construct a chimney, brick chimneys have still been very popular for many years.

Brick chimney

This type of chimney has its advantages. It cannot be plastered inside, which will help save on finishing materials. It is also worth considering that the masonry of a brick chimney must have a joint of 1 cm. If it is recommended to use cement-lime or lime mortar indoors, then in the upper part of the building you can already use ordinary concrete mixture for masonry.

Advice. In order to use a brick chimney in a house, it is necessary to make a more powerful foundation for the building - brick will add extra load to the walls of the building and to its foundation.

In addition to the advantages, there are also a certain number of design disadvantages. Brick, due to its rough surface, can accumulate dirt. That is why such a pipe becomes clogged with soot very quickly.

Since combustion products exit through a brick chimney, oxygen condensate is formed, which causes brick pipe subject to destruction. It happens that a piece of brick breaks off and falls into the pipe. All this can significantly narrow the chimney channel and make it difficult for air masses to escape.

To ensure a long service life of a brick chimney, it is recommended to insert an asbestos-cement pipe inside. The gap between the brick and the pipe is filled with concrete mortar.

An example of using an asbestos cement pipe

Ceramic structures

Ceramic pipes are ready-made structures for constructing a chimney. They are for sale modular design. Her inner tube made of acid-resistant, heat-resistant and durable ceramics.

Ceramic chimney pipes have a number of advantages and have a very smooth surface. Thanks to this, soot does not accumulate on it, which is formed as a result of the passage of contaminated air masses formed during the combustion process.

Installation of a ceramic pipe for a chimney

Like brick chimneys, ceramic chimneys are quite heavy. It is for this reason that it is worth using a foundation for the structure.

Metal chimneys

As for metal pipes for the construction of a chimney, due to their ease of Lately began to enjoy great popularity. They also have a smooth surface, which eliminates the accumulation of soot. Accordingly, the air will flow much better.

Laying sewer pipes inside a private house and in the ground

High-quality thermal insulation is quite simple. For this purpose it is used basalt wool, which is laid inside the pipe. It will only be necessary to correctly determine the thickness of the material, since a large thickness can completely or partially block the pipe and it will be very difficult for air masses to escape.

Device metal pipe chimney

As a rule, metal chimneys are made from of stainless steel, which is very resistant to all climatic, weather and other influences.

Modern chimney pipes are polymer structures. The pipe itself is very soft and has quite a small weight. The chimney will be distinguished by its practicality and durability. You can install the pipe yourself, and any beginner can handle it.

Modern polymer chimney

Most often used polymer pipes if the house has a system gas heating(boilers or columns). Such pipes can only be inserted into a chimney that is made of brick.

Types of chimneys

Today there are two types of chimney structures: a structure located inside the building and a chimney outside the house. They differ not only in the materials from which they can be constructed, but also in size and type.

Drawings and design of internal and external chimneys in a private residential building

Typically, to build a chimney inside a house, brick or ceramic pipes. It is more rational to use metal chimneys outdoors, as they are resistant to temperature changes and are not exposed to moisture.

A chimney inside the house can also be made in two ways, more about this in the video

The chimney can be used in both brick and wooden building. Only chimney in wooden house must be properly constructed, as wood chars very quickly. Eat special technology construction of a chimney in a wooden building.

Construction of a chimney in a wooden house

Most often, there are several chimneys in a wooden house. But the number of such structures largely depends on the amount of equipment used in the house. The house must have a heating system with a separate chimney and may have a fireplace, which also has a separate chimney.

All chimney structures in the house must be installed on the roof of the building and made in compliance with all norms and standards.

Chimney in a wooden house

In order to properly build a chimney in a wooden house, you need to draw up project documentation and contact specialists in this field who can correctly draw up a chimney project.

The life safety of everyone living in the house depends on a properly built chimney, and the equipment itself will work better. The latter applies to gas heating boilers and pipes for fireplaces.

The chimney in a wooden house should only be in a vertical position. Of course, there is an exception to the rule. You can build it with a deviation that is no more than 30 degrees from the vertical position. If it is necessary to bring the pipes outside, and this cannot be done without moving the chimney pipe, then the size of such a transfer can be no more than 100 cm.

Options for building a chimney in a wooden house made of timber

As for the removal of the chimney on the roof of the building, it will largely depend on the type of roof and the type of roof itself.

Advice. When building a chimney on the roof, it is worth considering the direction of the wind, which is most common in this region. This is necessary due to the fact that if the chimney pipe is connected to a heating boiler, then wind masses can enter the pipe and thereby cause intermittent combustion of the fuel substance.

If there is, then the smoke exhaust pipe must be constructed with high quality. This will prevent smoke from entering the room and allow it to escape outside.

Recently, a chimney for a fireplace in a wooden house is quite complex design, which uses pipe-in-pipe technology.

The chimney itself consists of three components:

• stainless steel pipes;
• layer of thermal insulation material;
• steel pipe.

Initially, the stainless steel pipe is wrapped thermal insulation material, which can be secured to it using wire or any other material. After that finished design inserted into a metal pipe, which will have a larger diameter than the inner one.

Methods for installing chimney pipes in a wooden house

In addition to this method of constructing a chimney, there is another way; a plastic stocking is used for this. Its main advantage is that it heats up very quickly and cools down quickly. It can also be used when it is necessary to make a fairly large number of chimney passages.

A chimney is a mandatory attribute of any stove, thanks to which the resulting combustion products are removed from the heating system. The chimney is most often made of a metal pipe. It creates a draft, with the help of which all gases escape along with smoke.

Chimney requirements

Mount metal chimney for the stove you can do it yourself, the main thing is to do it correctly, otherwise due to incorrect calculations the load on the heating system will increase, the room will become smoky, etc.

Main characteristics of any chimney:

• form;
• material;
• size.

The first thing you should pay attention to when buying a chimney pipe is its shape. Experts recommend using cylindrical pipes; they are better than others for removing waste gases and smoke.

Many owners of fireplaces and stoves are wondering how to clean a chimney? And this is no coincidence, because a decrease in draft can lead to failure of the chimney and fire. Let's look into this issue.

Important! The chimney for the stove should have as few corners, sharp transitions and obstacles as possible. Otherwise, a lot of soot and ash will settle on the walls of the pipe.

The material from which the chimney is made is no less important. If we're talking about For environments with high acidity, it is best to use stainless steel pipes with molybdenum. Stove chimney You can also lay it out of brick, but the most popular material is alloy steel. We previously wrote about and advised you to bookmark the article.

The size of the chimney directly depends on the size heating structure(furnaces). To correctly determine the height of a structure, you need to seek help from building code documents. Errors in calculations lead to a decrease in draft and the appearance of traces of soot in the room. In order not to make a mistake with the diameter and length of the pipes, you can use a suitable finished project with dimensions from the Internet.

Basic requirements for metal chimneys:

• Pipes must be well insulated.
• Before installing the chimney you need to do correct calculations and prepare a project.

Compliance with these rules will allow the chimney to function without such consequences as smoke in the room, soot deposition, carbon monoxide inflow, etc.

Installation rules

• If the chimney pipe rises more than one and a half meters above the roof, then it must be additionally secured with brackets or braces.
• The height of the metal pipe from the furnace to the head must be at least 5 m.
• To remove condensate, special plugs are installed in the chimney.
• In some heating devices, the temperature of the exhaust gases is very high, so the ceiling surface must be additionally insulated. The craftsmen also recommend using special parts during installation, for example, an insulated passage through the ceiling.
• The chimney must extend at least half a meter beyond the roof.
• When installing a chimney pipe, it is unacceptable to “narrow” its diameter.
• Horizontal sections of metal pipe should not be more than 100 cm in length.
• If the pipeline is laid near structures made of flammable materials, then it should heat them by no more than 50 degrees Celsius.
• The chimney must be located at a safe distance from the electrical wiring, gas pipeline and highly flammable building materials.

Tools and materials

You can install a metal chimney for a stove yourself; for this you need to prepare following materials and tools:

• metal elbow;
• connecting elbow;
• metal pipe;
• sealant (We recommend reading the material about);
• spark arrester;
• thermal insulation;
• brackets or other fastening elements;
• anti-spill canopy;
• tee with condensate drainage, etc.

Note: There are two types of tee for collecting condensate and cleaning the chimney: 90 and 45 degrees. It is usually sold with a special plug. It can be blind or with a condensate drain.

Parts for installing a metal chimney - elbow, tee, plugs, etc.

Installation stages

Stove chimney, and in this case we will talk about installing a pipe for a potbelly stove standard sizes, mounted as follows:

• The first piece of metal pipe is fixed in the chimney opening in the stove using sealant.

• The knee is built up, moving up to ceiling or windows.

Important! The pipe must be secured to the wall with brackets every two meters.

• Having reached the ceiling, a hole of the required size is cut and the thermal insulation is removed. The size of the passage must be at least 70 mm larger than the diameter of the pipe.

• The pipe is brought out through the passage glass and fixed at the attachment point with the external chimney.

Advice! The joints of elbows, pipes and tees are additionally secured with clamps. After completion of the work, they are additionally sealed.

• Next, attach a tee to drain condensate.

Advice! If the chimney will be discharged through a window, then a pass-through glass is installed in the glass hole.

• The external chimney is covered with bitumen and provides adequate thermal insulation.

• A spark arrestor is attached to the surface of the pipe, popularly called a “mushroom”. It protects the chimney not only from flying sparks, but also from precipitation and small debris.
• At the end of the work, an umbrella is installed on the chimney.

• Places of pipes that may be susceptible to corrosion are treated with heat-resistant paint.
• After all installation work After installing a metal chimney, a test firing of the furnace is carried out. Check the tightness of the structure and the heating level.

Important! When testing the oven with just installed chimney A burning smell or light smoke may appear from the metal pipe. This is due to crystallization of the sealant composition and evaporation of oil from the surface of the pipes.

Efficient operation of the chimney for wood stove and other types of heating devices depends not only on the correct installation and calculations. The chimney needs constant maintenance. It is necessary to regularly monitor the condition of the pipes for burnouts, rust, corrosion, and clean them. During operation of the furnace, traces of soot and soot remain on the inner surface of the pipes, which make the cross-sectional diameter of the pipeline narrower. In addition to natural combustion products, traces of plastic waste may settle there. Sometimes the chimney becomes clogged due to the appearance of wasp's nest etc. Experts recommend carrying out cleaning work at least two or three times during the heating season.

For cleaning you can use:

• aspen firewood - burning aspen quickly removes soot;
• flexible thick cable for hard-to-reach places;
• burning together with special fuel chemical compositions and etc.

Video: DIY metal chimney installation

You can install a metal chimney for a stove with your own hands. To avoid unpleasant consequences, you need to strictly follow the instructions and not be creative.

Homeowners, as a rule, take the organization of heating in their homes very seriously, choose the safest boiler models, and turn to experienced stove makers. However, what is sometimes overlooked is that incorrect chimney installation is often even more dangerous.

Chimney pipe – essential element heating system in a private house, the assembly of which is carried out in accordance with building codes and requirements fire safety. Installation of a chimney carried out without following these rules is fraught with irreversible consequences - a fire or poisoning in the house carbon monoxide. Today’s article will tell you about the types of chimneys, their design and installation methods.

The chimney pipe serves to transfer smoke and combustion products into the atmosphere; it starts from the inlet pipe of the heating device in the house and ends above the roof ridge with a protective umbrella. In private construction, the following types are mainly used:

The material from which the chimney is made can be selected correctly based on three factors: compliance with the material of the heating device, low thermal conductivity and tightness of the connections.

Chimney outlet methods

The main task of a chimney is to remove smoke outside the house, which can be organized in several ways. The choice of pipe insertion location depends on the location of the heating device, free space and type of chimney. Use the following options pipe placement:

External placement is well suited for the bulky design of a brick chimney, but if you lead a metal pipe through the wall, you will have to take care additional insulation or using special sandwich pipes.

Chimney requirements

The selection of elements is carried out taking into account the requirements technical characteristics heating device. In order for the system to operate smoothly, the basic principles of chimney design must be observed:

1. Preferred round form, since combustion products and dust accumulate in the corners of the pipe. Round chimneys require cleaning less often than rectangular and square ones.
2. The cross-section of the pipe should not be less than the diameter of the heating device pipe. It is calculated that for every kilowatt of power, 8 square meters are required to ensure the proper level of thrust. cm sections. Usually information about required size the chimney is contained in the instructions for the heating device.
3. Each heating device requires the installation of its own chimney. In some cases, you can deviate from this rule, but then the devices must be located at a different height, the distance between the connection points is 1 m or more. And the size of the pipe cross-section should take into account the total power of the heat generators.
4. The total length of the horizontal sections of the chimney cannot exceed 1 m; violation of this rule reduces the draft force.
5. The chimney ends 0.5-1.5 m above the ridge, at flat roof– 0.5 m above the surface.

The main criterion for selecting pipes is fire safety requirements and compliance with the heat-generating device, appearance, aesthetics and saving space inside the house are secondary.

Installation sequence

Installation internal chimney begins with drawing up a diagram and calculation required quantity pipe segments. To assemble correctly, the device is performed in the following order:

Scheme of the chimney outlet through the corrugated roof

After installation is completed, it is necessary to start the heating system, check the draft and tightness of the connections - even a small amount of smoke indicates serious problems, the solution of which is unsafe to postpone.

Installing a chimney in a house is a responsible undertaking, the quality of which determines the comfort and safety of operation of the heating system, so follow the manufacturers’ recommendations and installation technology.
