Heating equipment mounted on walls and ceilings, including portable heating devices, to a certain extent is an integral part of the interior, requiring decoration and occupying some volume in the room.

With the development of production technologies heating equipment units have appeared on the heater market that do not reduce the usable volume of the premises -, flush built into the floor

Group sequential arrangement under a common grille of convector-type heaters installed in the floor along the perimeter of a circular arrangement of panoramic window openings

In-floor heating convectors are widely in demand in spacious administrative and residential premises with glass enclosing structures, as well as public transit structures (corridors, passages, waiting rooms), where they, without being conspicuous, effectively fulfill their purpose - maintaining the required temperature regime.

General understanding of floor-mounted convectors

Convectors that are simply built into the floor are a durable rectangular body, often framed, covered on the front side with a decorative metal grille. The housing contains a heat exchanger that is heated, depending on the type of heating device, by the coolant or electric heater circulating through it.

In-floor heating convectors are installed in separate point or common linear niches made in load-bearing floor according to the size of the heaters, as well as in the space between the raised floor and the concrete base. To reduce heat loss, the bottom and side walls of the casing of in-floor convectors are equipped with external thermal insulation.

The design of such heaters includes adjustment screws that allow precise adjustment of the horizontal position of the front grille plane to the level finishing coating floor so that the protruding parts of the body do not create obstacles when walking on them.

For more effective use floor-mounted heaters are located along panoramic glass enclosing structures and window openings in order to use convective currents as well as thermal curtain between the space of the room and the cold surface of the glazing.

Types of in-floor heaters

There are many models of in-floor heaters produced today, and they all differ in some way from each other. If we do not consider parameters that are of secondary importance, then all built-in deep into the floor Heating convectors can be divided into two groups:

• water;
• electric.

The units within each of these two groups differ in size, configuration, power, design of the external grille, type of convection - natural or forced (with fan) and performance class.

Water heaters for internal floor placement

An underfloor water convector is a heating device connected to a central or autonomous heating system.

Functional diagram of a water in-floor convector - supply from glazing window opening to the cold air heating device, heating it and exiting it into the room.

A valve is installed at the point of insertion into the system, which can be used to regulate the amount of coolant circulating through the floor water heater.

The main element of the unit is a radiator with inlet and outlet fittings, through which flexible hoses or fittings are used to connect to the heating system, and hot water circulates through the heat exchanger.

Connecting the radiator of a floor-mounted heater using flexible hoses.

The radiator is made of copper pipe, on which aluminum fins are made to increase the heat exchange area. Modern water heating convectors are equipped with automatic release valves for air entering the system along with water, which eliminates the formation air jams and ensures efficient operation of the unit due to the stable intensity of coolant circulation.

Installation of a water convector in a niche and its rigid connection to heat-insulated pipes in grooved channels.

The intensity of the coolant supply to the convector can be manually changed by a valve at the point of connection to the heating system, but it is more effective to install a mechanical thermostat at the inlet of the heater that regulates the flow of hot water into the heat exchanger depending on the temperature of the water in the radiator.

On the left is a schematic cross-section of a manual valve and a mechanical thermostat, on the right is a natural image of the thermostatic head.

Floor-mounted heaters with a natural type of convection are designed for heating medium-sized rooms (16-25 sq. m.).

To ensure the natural movement of convective flows, the depth of the housing box must be at least 20 cm, and yet even multi-pipe devices of the natural type of convection do not always cope with the role of the main and only means of heating, forcing homeowners to additionally use other heating devices.

The main advantage of this group of in-floor heaters is safety due to the absence of factors associated with the use of electrical appliances. In-floor water heating convectors do not require grounding, are not afraid of direct contact with moisture (this often happens on the floor), the surface temperature of these units is safe for humans upon short-term touch, and the outer grille can be made of valuable species wood

Methods of arrangement of floor-mounted heaters: on the left - corner placement, on the right - installation in steps.

The cost of such devices, depending on the power, class of technical equipment and design, ranges from 20 to 100 thousand rubles.

Important! When connected to the system, water heating convectors built into the floor are heaters that do not require energy costs (with the exception of models with a fan).

Forced convection type water heating devices

Equipping the device with a fan accelerates convective flows, but at the same time reduces their temperature - the air heats up less due to the shorter duration of contact with the heat exchanger. Therefore, radiators of in-floor heaters with forced convection are made more complex design(two-three-four-pipe), up to 3 meters long, which prolongs the contact of air with the heat exchanger and increases its temperature at the outlet of the unit.

Conventional diagram of the movement of convective flows in an in-floor convector with a fan.

A heater built into the floor with forced convection is many times more efficient than models without a fan, therefore they are used in large areas, and the energy consumption of such devices due to the lack of electrical heating elements not much. However, the complexity of the design used most often in modern heating units tangential type fans (with reduced level noise, operating from a voltage of 12 V) or the equipment of the heater with several ventilation mechanisms of a traditional, diametrical type design significantly increases the cost of the convector, which can range from 50 to 160 thousand rubles.

Types of fan equipment for trench convectors: on the left - single, on the right - block, below - tangential fan.

The thermal power of a water heater is determined by the dimensions of the unit, the temperature of the supplied coolant and the type of convection, but the required calorific value (Qt) is determined by a special formula:

Formula for calculating the required power of a convector with a breakdown of the constituent elements.

However, the required heat release power also depends on other factors - region, room dimensions, glazing area, degree of thermal protection of enclosing structures, etc., therefore, its value is often determined using special tables that take into account certain operating conditions.

Electric underfloor heating units

These units differ from water in-floor convectors in the way they heat the heat exchanger and, naturally, in their design.

The heat exchanger is a heating element placed in a finned housing. Thus, electric floor-mounted heaters are to some extent infrared heaters, the basic operating principle of which is based on convection.

Schematic diagram of an electric in-floor heater of natural convection type.

The presence of an electric heating element in the unit allows it to be connected to the system automatic control heating to minimize human participation in the operation of the heating device. To do this, an external mechanical thermostat is installed in the power supply circuit of the unit, which turns off the device when the room temperature reaches the set value.

Important! Automatic temperature control is effective only when installing units with a forced convection type, since the fan ensures uniform air temperature in the room and allows the temperature sensor to record its real value.

Option for wired connection of a thermostat to a floor-mounted electric heater.

All models of electric in-floor appliances are equipped with an internal temperature sensor that protects the heater from overheating.

Important! When marking the installation of electric heaters, the distance from the unit to the glazing plane should be no more than 300 mm - if this value is exceeded, nothing will prevent the formation of condensation on the glass, which, flowing onto the floor, can accumulate in the niche where the heater is located.

The height of the ceilings of most apartments does not allow painlessly pouring a layer of concrete onto the floor, allowing the in-floor heater to be recessed. It is also unrealistic to ditch the floor in the interfloor ceiling to such a depth. Therefore, an electric, and even more so a water heater built into the floor, in conditions apartment building you won't meet. But floor convectors that are similar in design are produced and do not require installation of mounting niches in the floor for installation.

Such heating devices, both electric and water, can effectively heat spacious rooms in apartments and domestic premises for industrial purposes.

Important! The use of electric trench convectors is associated with sensitive energy costs, but there is a way out of this situation - the use of a network direct current 24 V voltage, which will not only reduce costs, but also increase the safety of operation of the heating unit.

Schematic connection of an in-floor convector to a 24 V network and a thermostat

Fan coil units

Based on floor-mounted convectors, another type of heater is produced that works not only for heating, but also for cooling. Depending on the installation location, in addition to the internal one, they are also wall, floor and ceiling. The Russian-language name for such a unit is fan coil - from the English fan-coil, which means fan-heat exchanger.

This definition means a combination of two devices working in pairs:

• fan coil itself - a floor-mounted mechanism for influencing air temperature, including one or more heat exchangers;
• chiller - a separately installed unit for cooling the coolant (water) supplied to the fan coil in the summer.

Fan coils are single-circuit (two-pipe) and double-circuit (four-pipe).

In single-circuit units, hot water from the central heating system or antifreeze from the heating boiler is passed through a heat exchanger in winter. In summer, the same heat exchanger passes cold water from a chiller - a device that does not use freon or other gas with identical characteristics for cooling.

In double-circuit fan coils, the movement of hot and cold coolants is carried out through separate heat exchangers.

Schematic representation of a double-circuit fan coil unit (without a chiller).

Thus, depending on established mode, the fan forces room air through a hot or cold heat exchanger.

There is no universal scheme for installing a chiller-fan coil system pair; its installation is possible in any room, but the installation project will be tied to specific conditions.

One chiller, correctly selected in terms of power, can be connected to a system of many fan coil units (wall-mounted, ceiling-mounted, in-floor), serving several rooms and even buildings.

This system for ensuring the required temperature in rooms is used mainly in public and industrial buildings, as it is difficult to maintain and expensive.

Advantages and disadvantages of floor-mounted convectors

We list the positive and negative features of in-floor heaters without dividing them by the type of energy carrier used and listing the characteristics inherent in all convectors as a whole.

Pros:

• due to the location of the unit, the lower, coldest layers of air are heated;
• installation of devices does not reduce the usable volume of the room;
• quick access to working mode;
• preventing the formation of condensation on glazing.

Minuses:

• at high ceilings installing natural convection units into the floor is not effective - convective flows of heated air are concentrated high under the ceiling and cool down before they fill the actual volume of the room;
• convection from level flooring initiates intense movement of dust in the air, which is constantly present in the air during heater operation;
• inconvenience of daily care of niches in which household waste accumulates.

Conclusion

Floor-mounted convective heaters are perfect heating devices that not only heat the room, but also create a thermal curtain between the living volume of the room and cold sources - glazing, doorways. But their installation must be justified by operating conditions, and not be an end in itself. Placing in-floor heaters in a room without a technically sound justification will only lead to the presence of littered niches in which devices that are not effective in the given situation and therefore not used are built in.

The main point of the article

1. In-floor placement of household heaters is the most rational option for installing heaters.
2. Floor-mounted heating devices are divided into two main groups: water and electric. When choosing the optimal heater for the existing conditions, knowledge of the structure and technical characteristics of both types of devices is necessary.
3. Water trench convectors are economical, safe and efficient heaters, possible to be equipped with shut-off thermostats.
4. Electric heaters installed in the floor cannot be called energy-saving devices, but switching to 24 V DC effectively solves this problem.
5. Fan coil units are perfect indoor temperature control units, but due to the complexity of maintenance and high cost, they are almost never used in private housing.
6. The use of in-floor heaters in rooms with a small area or in the absence of panoramic glazing not justified.

The Moscow Heat Company always has a large assortment of built-in in-floor convectors. Price for this type thermal equipment is within the range accessible to most consumers.

In-floor convectors differ from other types of heating equipment in that they are built directly into a specially prepared niche in the floor or in cement screed. The catalog of our online store presents two main types of floor-mounted convectors, which differ in the method of creating a thermal curtain:

• convectors that provide intensive air heat exchange thanks to the built-in fan;
• equipment in which air convection occurs naturally.

The price for in-floor heating convectors in our catalog is formed depending on their design features, technical characteristics, as well as from the manufacturer of thermal equipment.

Heating devices with natural air circulation are mainly used as secondary heaters. While built-in convectors with a fan can work as an additional or main heat source to heat the room.

Design features of trench convectors

A classic built-in floor water convector consists of a channel, a heating element and decorative panel, which hides all the “insides” of the heating device and protects them from negative external mechanical influences. The heating element is connected to the centralized system heating a building or structure and uses its coolant in its work. As a rule, experts recommend a convector built into the floor for installation in vestibules, doorways, staircase landings, in winter gardens, etc.

It is worth noting that the organization of underfloor heating should take place at the building design stage, since subsequent work associated with the installation of the system can lead to certain inconveniences.

Advantages of trench convectors

The trench convector has a number of undeniable advantages compared to other heating equipment:

• decorative panel mounted at floor level, saving space;
• low cost;
• attractive appearance.

Our company's catalog presents a wide variety of underfloor heating devices and systems that will ideally fit into any stylistic direction of the interior thanks to the large color scheme protective panels and a variety of equipment sizes. In order to buy an in-floor convector from the Moscow Heat Company, you just need to visit the section of our catalog, select heating equipment and fill out a special application form.

Prices for built-in floor convectors in our online store are lower than the market average, since our company works with many well-known manufacturers of heating equipment without intermediaries.

The desire to make the room as free as possible, while providing it with heat, led to the emergence of built-in equipment. The use of such units, which are located under the floor covering, allows you to preserve the aesthetics of the interior as much as possible without cluttering the walls. In addition, the in-floor water convector is designed for long-term use and may well become the basis heating system.

Modern devices and their scope of application

Heating device design

The need to maintain a comfortable microclimate in the room requires the installation of special equipment. But not every property can install a classic radiator heating system.

Moreover, in most cases this is due to the specifics of its work. For example, for buildings with a large glass area, built-in convectors are considered the most suitable. Since their operating principle is considered optimal for swimming pools, greenhouses and other similar objects.

Equipment of this class is quite different simple device. The built-in water convector is a heating element made of copper-aluminum alloy. This composition was not chosen by chance, since it has maximum corrosion resistance. Therefore, a convector made from it will last a long time.

The heat exchanger is placed in a housing made of thick steel sheets. They protect the floor covering from moisture penetration in the event of equipment leakage.

The in-floor convector is installed in a specially equipped niche or directly in a cement screed. The equipment is covered from above with a decorative grille, which also protects the inside of the unit from mechanical impact. It is located flush with the floor covering and can be made in any shape and color in accordance with general style interior

Types of embedded equipment

Trench water convectors are available in two modifications:

Devices of the first type are intended for use as auxiliary ones. They are usually installed in places where cold air passes near doorways and windows and act as a thermal barrier.

Units with forced convection are equipped with a built-in tangential fan. It is necessary for intensive heat exchange in the room. Such convectors are used as the main heating devices.

To expand the functions of in-floor equipment, it can be connected to a temperature control system.

Advantages and disadvantages of in-floor convectors

Devices of this class find wide application in a wide variety of rooms. But most often they are still used for heating objects with a large glass area and floor-length windows. In such a room, an ordinary radiator will look defiant.

Not only will he not fit into general interior, but will also limit the view from panoramic window. Therefore, in-floor convectors are usually installed in them.

But besides this, the device has a lot of other positive features, such as:

• Possibility of saving free space;
• Various standard sizes;
• Reliability;
• Protection against condensation on glass;
• Long service life.

Among the disadvantages, it is worth noting lower efficiency compared to wall-mounted or floor models. This is due to the fact that part of the heat is absorbed by the floor covering. One disadvantage of the Varmann in-floor water heating convector is the difficulty of heat exchange due to the specific location. But this drawback can be eliminated by using forced airflow of the heat exchanger. However, using a fan will lead to the loss of one of the advantages - silent operation of the device.

You should also take into account the fact that installation of an in-floor convector is much more complicated than a wall-mounted one. And if we talk about apartment buildings, then it is often simply impossible in them.

Review of popular models

The choice of heating equipment should be made in accordance with the characteristics of the room. After all, if the device’s power is insufficient, it will not be able to provide the required temperature, and if it is overpowered, its use will be unnecessarily costly. But in addition to technical characteristics, the manufacturer’s brand is also taken into account.

Internal floor convectors brand Breeze

The reliability, quality and cost of the convector depend on this parameter. Among large quantity various models The devices from the following companies are in greatest demand:

Convectors from a domestic manufacturer have a heat exchanger made of copper-aluminum alloy. They are able to quickly raise the room temperature to a set value. In this case, the main structure of the device, if installed correctly, will be hidden, and only the decorative grille will remain visible.

Trench water heating convectors Kermi are products of the Belgian company Acotherm. They are intended for use not only as additional, but also as the main devices of the heating system. The main difference between this brand’s equipment is its low height, which allows it to be installed under almost any type of floor covering.

Kermi convectors are produced in a wide range of capacities, and there are devices with forced and natural convection. Most models are equipped with a thermostat and can work autonomously.

A wide range of products, which includes devices up to 3000 mm long and up to 140 mm high, allows you to select units in accordance with the characteristics of the room. In addition, the manufacturer is ready to produce a custom-made convector with non-standard dimensions.

But not even high aesthetics and big choice make this equipment popular. The most attractive aspect is high quality products of the Kermi company, confirmed by the extensive experience of the manufacturer. Therefore, the convectors are guaranteed for 10 years.

The advantages of this equipment also include the following parameters:

1. Safety of use, since the fans are powered from a 12V source;
2. Easy installation;
3. Easy to clean the convector from dirt and dust.

In addition, the device includes a bath with fasteners, as well as flexible connectors, an air vent and a board for securing the channel during transportation and installation. If necessary, any of the elements can be ordered separately.

Consumer Opinion

They all claim that trench convectors are much more efficient than classic radiators and also have a higher thermal output. Their installation allows you to quickly heat the room, and when used in conjunction with a temperature control system, the devices provide full climate control.

Trench convectors

Trench convectors- one of the most modern devices, which allow you to heat a room, regardless of its size and design. Such hidden heating devices are very convenient and allow you to maintain desired temperature even in huge rooms with stained glass windows, or with solid glass walls. Unlike batteries that are common to all of us, trench convectors do not take up extra space, and also fit perfectly even with an elegant design.

Until recently, it was believed that this type of heating was an incredible luxury. But now in-floor convectors have become available to many. They are actively used for heating new buildings, in the private sector, swimming pools and retail premises. From exclusive heating devices, such convectors have become mass-produced.

Where are trench convectors used?

• The main purpose of in-floor convectors is, of course, space heating. These devices are an excellent alternative to conventional radiator heating, based on the familiar water system. But, in comparison with conventional radiators, convectors built into the floor benefit from their compactness and virtual invisibility. They fit perfectly into the interior and even complement the design of rooms with huge window openings or continuous glazing as walls.
• The next, no less important purpose of in-floor convectors is the absolute resistance to condensation on windows. Forced convection provides a phenomenon when air flows from the convector become an obstacle to cold air penetrating from the window. This allows the windows to remain dry and clean even with severe temperature fluctuations.

Price and comfort. What do you need to know when purchasing a trench convector?

As mentioned above, convectors built into the floor They are distinguished by the fact that they perfectly heat the room while remaining invisible. This becomes possible due to the fact that the device is installed directly under flooring. In addition, an in-floor convector can perform several functions at once, which is why it is often indispensable in modern buildings. Considering these features, we can conclude that its price is commensurate with its quality. Of course, in-floor convectors are more expensive, but the cost-effectiveness of their use and comfort will certainly please the owners.

The right choice of in-floor convector is the key to comfort

Speaking about choosing an in-floor heating convector, it should be noted that each type of these devices is good in its own way. But you should choose based on the specifics of the room. For example, batteries built into the floor, which operate solely due to natural convection, will be optimal in rooms that do not require strong heating. They are ideal for maintaining temperature conditions, which significantly differs from devices that operate under mechanical influence on air flows.

Convectors built into the floor, the operation of which depends on the power of the fans, have proven themselves to be excellent in retail spaces or those entertainment centers where the area of ​​the heated space is quite large. They are also beneficial in winter gardens, swimming pools and game rooms.

Why should you choose an in-floor convector?

• Such convectors are quite reliable;
• Modern heating devices connect perfectly to various types pipes (autonomous and central systems heating);
• Trench convectors are economical and efficient;
• The devices do not spoil the design at all and are often even part of the decor of the room.

How to regulate the operation of floor convectors?

Regulation of the operation of underfloor water heating convectors depends on the method provided by the manufacturer. Most often, regulation occurs thanks to a thermostat, which is equipped with a special sensor, or using a control thermostat. If the former are convenient for heating private houses with small area, then the latter regulate the operation of the fans and are ideal for large areas with stained glass windows.

How to choose a convector for rooms with a specific design?

It should be noted that convectors built into the floor, among other things, perfectly replicate the architectural forms of the most sophisticated forms. You can buy in-floor convectors in Moscow based on the characteristics of the room. There are radius and corner convectors, which are installed in accordance with the shape of the room. While corner convectors built into the floor are assembled in accordance with the degree of the angle, radius convectors have a curved shape and follow the lines of window openings.

Trench convectors - convenience and style for your room

So, we have already figured out that built-in convectors can satisfy any, even a very picky client. You can now buy in-floor convectors in Moscow at an affordable price without much difficulty. By installing such a convector directly into the floor, you can not only gain additional space, but also provide your room with an economical heating device without compromising the design.

In-floor (built into the floor) water heating convectors

Trench water heating convectors are a modern and effective solution in cases where it is necessary to provide the room with heat and at the same time maintain the aesthetics of the interior, since the walls are freed from unnecessary elements, and all heating radiators are located in the floor.

Floor-mounted convectors are installed in apartments and private houses, car showrooms, entertainment venues, hospitals, shops and other organizations. In rooms with a large glass area - swimming pools, greenhouses, airport buildings, on terraces country houses and cottages - optimal choice There will be an underfloor heating convector.

The price of an in-floor water convector depends on the manufacturer of the device, its size and type, design features and technical characteristics.

Design of underfloor heating convectors

A water heating convector built into the floor is a heat exchanger placed in a special casing. The heat exchanger is a copper-aluminum heating element, highly resistant to corrosion, which is connected to a water heating system.

The casing of a built-in convector is usually made of thick sheets of galvanized or stainless steel and provides reliable protection floor covering in case of possible leakage.

The casing with the heat exchanger is installed in a pre-prepared niche in the floor or directly in a cement screed and covered with a decorative grille, which makes invisible and protects the inside of heating radiators built into the floor.

In other words, the visible part of the built-in convector is a decorative grille located at the same level as the floor covering, which can be made of various materials with a wide variety of textures, shapes and colors, and also additionally painted in the required color, in accordance with the wishes of the client.

Types of underfloor heating convectors

• convectors with natural convection;
• convectors with forced convection, with a built-in tangential fan that promotes more intense heat exchange.

As a rule, convectors with a fan are used as the main heating device in the room.

Convectors with natural convection are auxiliary heating devices. They are designed to insulate large windows and doorways from cold air and are used with underfloor heating or radiator heating systems.

A control system can be connected to in-floor convectors of any type.

Advantages of underfloor heating convectors

Water convectors built into the floor have undoubted advantages compared to conventional heating radiators:

In-floor (built into the floor) water heating convectors

In-floor (built into the floor) water heating convectors In-floor water heating convectors are a modern and effective solution in cases where it is required to provide

Heating appliances in which thermal energy from the coolant or heating elements enters the room through convection, called convectors. In-floor devices have significant differences from many similar devices and are built into pre-prepared niches in the floor or cement screed.

What is a trench convector and what is it for?

Trench convector is a new generation heating device, widely used as additional source thermal energy and for indoor organization efficient heating primary type. From a constructive point of view, all built-in convectors are fin heat exchangers installed in a reliable metal casing, covered with a decorative grille.

The grille mounted on top of the convector performs not only a protective, but also a decorative function.

The materials used in the manufacture of the grille and housing are selected depending on the power indicators, purpose and design intent.

The installation of in-floor convectors is currently in demand in different types of premises, represented by:

• apartments and cottages with panoramic glazing;
• public spaces, hotels and office buildings;
• sports clubs and halls, swimming pools and spas;
• winter gardens, greenhouses and greenhouses;
• exhibition and concert halls, museums and libraries;
• shopping centers and car showrooms.

In addition to heating, the convector prevents fogging of panoramic windows

As a rule, water-type heaters built into the floor are installed in rooms with fairly high humidity levels or a special design, including hallways, flights of stairs, areas near the entrance or balcony door, where devices of this type not only warm up the air, but also prevent fogging of the glazed surface.

The original version of the heat exchanger of an in-floor convector is connected to the heating system, which contributes to the most efficient heating of indoor air. Additional elements, such as small fans, can also be installed in the device case, which improves air heating, as well as various regulators. Sometimes this type of heating system is referred to as fan coils built into the floor, which is an incorrect definition.

Device and general principle of operation

In-floor convectors, similar in appearance, are quite capable of becoming a good replacement for any traditional wall-mounted heating radiators. Exactly enough simple principle The operation of in-floor heaters is determined by the name of such devices. Thanks to the special design, thermal energy is transferred as efficiently as possible through convection.

The fan in the system supplies heated air

Passing the cold air flow around the heat exchanger causes an increase in temperature and a decrease in the density level, which is accompanied by the rise of heated air upward and its entry through the decorative grille into the room. Instead of rising warm air masses, air with a lower temperature regime rushes into the heating device.

The device provides cold air in and warm air out

Devices installed in the floor are most often made on the basis of a stainless or galvanized steel body, which is characterized by increased resistance to corrosion.

The body of the device contains many parts, including several decorative grilles and a heat exchanger

The diagram shows the components of the convector:

• 1 - device body;
• 2 - internal heat exchanger;
• 3 - decorative grille;
• 4 - AC tangential type fan;
• 5 - large decorative grille;
• 6 - small decorative grille;
• 7 - edging decorative profile;
• 8 - mounting and adjusting legs of the device;
• 9 - adjustment screws;
• 10 - mounting bolts;
• 11 - ball valve;
• 12 - shut-off and control valve;
• 13 - flexible liner;
• 14 - gasket.

The internal part of the device is equipped with a built-in heat exchanger in the form of a horseshoe-shaped curved copper tube. Aluminum fins are used to increase the surface area of ​​the heat exchanger. Top part The convector is equipped with a decorative grille made from wood, aluminum and steel.

The performance indicators of the device are influenced by the temperature regime of the supplied coolant and the intensity of the air flow that is created near the heat exchanger. Modern heating devices capable of functioning in a wide temperature range of the coolant - 45–90° C.

The built-in tangential ventilation element helps to increase the level of performance and the rate of heat transfer, through which the intensity of air flow increases.

Types and characteristics of equipment

In-floor convectors with natural and forced convection are represented by different types, which differ in their design and basic technical characteristics. All models produced today have a different method of heating air flows and the type of convection of heated air.

Mermen

The heating element in a water heater built into the floor is a hollow tube with pressed or welded plates. To transfer thermal energy in such structures, a coolant is used in the form of antifreeze or ordinary water.

The dimensions of the in-floor convector can be individual and depend on the room for which it is intended

Connection to the general water heating system is carried out by pipes with threaded connection. Special attention must be given to the heat exchanger. The most expensive elements based on copper and copper-aluminum alloy have the maximum power. Budget models feature steel and galvanized heat exchangers.

The convector is connected to the heating using a special fitting

The principle of operation is based on convection, represented by the mixing of hotter, rising air masses with cold air, which descends to the convector, and after warming up again rises towards the ceiling surface. The result of this operation is a gradual but noticeable warming of the air inside the room to the desired temperature.

Thanks to the special movement of air masses, the device gradually warms up the room

The advantages of in-floor water convectors are represented by smooth and uniform heating of the air in the room, low weight and compact dimensions, a completely modern appearance, as well as saving free space.

The only disadvantages include the possibility of dust accumulating under the grille and its spread throughout the room if the designer has fans.

Electrical

Underfloor electric convectors can operate on the principle of natural convection, that is, without installing fans, or they can be equipped with special ventilation elements to increase heating efficiency.

Fans built into the convector increase the efficiency of air heating

Models with a fan are the optimal solution and are installed mainly in rooms with very high heat costs.

The advanced electric built-in models have compact dimensions and a practical steel housing, and the latest generation components are used as equipment.

The equipment is characterized by silent operation, durability, and economical consumption of electrical energy.

The principle of operation of any electric models is based on the properties of thermal convention.

Electric convectors provide efficient air exchange

The only disadvantages include the absolute impossibility of operation in rooms with high level humidity and the need for professional installation of such equipment.

How to choose a trench convector

Competent selection of the thermal output of in-floor convectors is no different from calculating these indicators for traditional radiators. When making calculations, you need to remember that for each square meter For a heated area, it is necessary to expend 0.1 kW of thermal energy, and per cubic meter - about 40 W of heat, but taking into account a special correction factor:

• without wall insulation - 1.1;
• in the presence of single-layer double-glazed windows - 0.9;
• For corner room - 1,2;
• with a ceiling height of 280–300 cm - 1.05.

For example, to warm a room 300 cm long, 250 cm wide and 270 cm high, with total volume 20.25 cubic meters, you will need to install an in-floor convector with a power of 0.81–1.0 kW. When using the equipment as additional system heating, it is necessary to calculate the power at the rate of 20 W per cubic meter.

It is important to remember that the design power of the built-in water convector is determined at a coolant temperature of +75° C.

The total number of devices, as well as their dimensions, directly depend on the heat needs and are calculated at the design stage of the heating system, taking into account the expected heat losses.

The power of the device can be adjusted using shut-off and control equipment, represented by ball valves, manual valves and traditional automatic thermostats, which are mounted on the convector supply. The first option has a simple and sufficient reliable design, small dimensions and the ability to maintain the cross-section of the valves, but operation is allowed only in two positions.

The equipment regulates the power of the heating device

The use of a manual valve ensures smooth connection to the heating system and guarantees high accuracy in adjusting the heat output of the device, but in this case there may be a natural decrease in the flow capacity. Among other things, the constant presence of a person is necessary.

The best option is to equip the heating system with a thermostat with a remote-type sensor. Such a device will ensure stability and reliability of operation, as well as noticeable savings energy costs. Thermostats equipped with a servo drive are less commonly used. The presence of a stably functioning actuator in the design makes such models incredibly practical, and also has a positive effect on the dimensions of the entire installed heating system.

The device allows you to adjust the temperature using the adjustment dial

IN Lately Quite often, thermostatic type valves are installed on convectors, having a modern integrated temperature sensor, which is easily provided remote control operation of the device.

The most popular and in demand in our country, affordable models with decent technical characteristics:

• Briz (Russia);
• EVA (Russia;
• Itermic (Russia);
• Techno (Russia);
• Minib (Czech Republic);
• Varmann (Russia).

Installation and connection instructions

Installation of an in-floor convector is justified if there are elements in the room that form significant heat losses. Such areas can be represented glass doors“on the floor”, entrance areas to the loggia and exits to the terrace, as well as panoramic or stained glass windows.

Installation of water heating convectors

For execution correct installation And efficient work Installed device must adhere to several recommendations:

• a niche or channel is made with a recess of 1.0–2.0 cm from the full height of the device, as well as approximately 5–10 cm more in width and depth;
• the distance from the window is 5–15 cm, and to the left and right of the wall - approximately 15–30 cm;
• additional protective insulation and sound absorption increase the efficiency of the device;
• the optimal connection is using flexible hoses, which helps to easily and quickly align joints;
• a rigid connection with a supply valve in the form of a manual radiator valve, ball valve, or thermostatic valve is more reliable;
• It is imperative to install reliable shut-off valves on the return line.

The most difficult thing to install is a water in-floor heating system with a forced type of ventilation:

1. Lay the heating medium and electrical cable in accordance with the installation diagram supplied by the manufacturer.

   The first step in installation is laying the liner and electrical cable

2. Fill the floor in accordance with the dimensions of the channel allocated for the installation of the installed device.

   Before pouring the floor, it is necessary to accurately determine the size of the channel

3. Install the equipment in the prepared channel, perform horizontal alignment using adjusting bolts.

   After installation, the equipment must be leveled

4. Fix the convector inside the channel, insulate and seal the space around the device.

   For reliability, it is necessary to seal the space around the structure

5. Install the finished floor covering.

   After installation of the device is completed, you need to install a decorative grille and run the device for testing

In the process of designing a heating system, it is very important to correctly position the supply and return pipes, provide for water drainage and the ability to carry out pumping if air gets into the interior. In-floor water heating convectors with a forced convection option require mandatory connection to electrical network at 220 W.

Electrical installation

For self-installation the device should be purchased electrical cable and choose optimal scheme connections.

Standard installation diagram for in-floor electric convector:

• 1 - devices with convection properties;
• 2 - electrical wiring;
• 3 - 220 V power supply;
• 4 - module;
• 5 - thermostat.

The device is connected to the power supply using electrical wiring

Main stages of installation of electric models:

1. Install the convector into the subfloor niche.
2. Secure the device with the angles, screws and dowels provided in the kit.
3. Level the device using technological bolts.
4. Connect electrical cables to the installed convector.
5. Lay down thermal insulation materials, which are most often used polystyrene foam sheets.

The last stage is quite difficult and requires effort. Thermal insulation consists of the following parts:

• concreting;
• thermal insulation;
• seamless floor;
• fixing pad;
• adjustment according to height indicators;
• soundproofing;
• screed;
• finishing floor covering;
• eyeliner;
• raised floors;
• seals.

An obligatory stage in the installation of an electric convector is laying thermal insulation

At the final stage, performance testing is carried out installed system heating, filling the floor and laying the finishing floor covering, as well as screwing in the decorative lattice element.

Rules of operation and maintenance

The list of maintenance activities includes the following operations:

• dismantling the protective decorative grille, which is carefully removed from the installed guides;
• wet cleaning of the channel or convector niche with a rag pre-moistened in clean water without adding detergents;
• dry cleaning of the heat exchanger using a household vacuum cleaner;
• control measures aimed at visual inspection of the heating device in order to timely detect leaks or violations in the integrity of the insulation.

If no defects are identified during visual inspection, then the decorative grille is installed in its place. Detected leaks will require disconnecting the device from the network and calling a heating system maintenance specialist.

Underfloor heating water convector – the best option for arranging heating in rooms of any size. It is connected to a centralized or autonomous heating system. It ensures the creation of optimal temperature conditions in a short time. In in-floor heating convectors convection can be natural or forced, carried out using a fan, which is characterized by low power consumption and low noise.
