Heating convector regulator. Typical mistakes when choosing and installing a heating convector and how to avoid them. Trench convectors electrical connection

In a private house correctly, without mistakes, so as not to regret it later the decision taken? First of all, you should understand what a convector is and in what cases its use is justified. There are at least four design options for these devices, and each of them has specific features. You can avoid mistakes when choosing and installing convectors if you take into account some subtleties in advance.

Heating convector - what is it?

A convector is a heating device that implements the principle of mixing air heated by a coolant with the surrounding air. Any heater is surrounded by air, so the operation of radiators is also associated with convection, but not on such a scale. To organize a convective scheme, it will be necessary to make changes to the profile of the heating system, shifting the emphasis to the movement of air flows from the direct radiation of heat by the batteries.

There are several ways to implement this:

use convectors as auxiliary devices to increase heating efficiency;
apply only convective solutions if justified by calculations;
rely on devices with forced mixing;
install convectors with natural action.

Which option will be the best? This requires calculations, but you can get a rough idea of the principle itself.

Common types of convectors

Common mistakes when installing convectors - the result of a misunderstanding of the principle of their operation. A device that heats rooms using flows warm air, may have different designs:

wall-mounted design - a convector in the form of a panel radiator with fins and at least two panels (type 21 or 22) has a passive circuit and produces at least half of the heat in the form of surface radiation;
floor convector - in the vast majority of cases, provides heating due to vertically directed air flows and radiates a certain amount of energy through the top and side surfaces;
the in-floor device operates by convection, most of its external surfaces are hidden, it is not designed to radiate heat from the side parts of the housing;
the device may have a circuit with natural convection due to the tendency of warm air upward or a system of forced air injection by a fan.

There are solutions in the form of wall-mounted units with built-in fans, but they small sizes do not allow achieving high efficiency.

Typical questions about heating with convectors

We are interested in typical mistakes associated with the use of convector heating in the house. The most common questions asked by home owners about this matter well reflect the range of problems:

How to achieve maximum device performance?
Will the in-floor convector (fan coil) make a lot of noise?
At what distance from French glazing should devices be installed?
Is it possible to completely abandon radiators when using a convector?
Is it possible to use convectors together with heated floors?
How to install in-floor and floor convectors correctly?

How to properly install convectors in a heating system?

We will try to give answers point by point.

The maximum heat transfer of a heating device is a calculated parameter that depends on the characteristics of the device itself and the conditions of its use. A mistake when choosing a convector may be due to the fact that you installed a device designed for a coolant temperature of 85 C, but your heating system operates at 65 C. Taking into account heat loss during transfer, the device will not be effective.
The noise emitted by the convector is insignificant. If we're talking about Regarding the sound made by fans, you should choose a device with speed control. There are convectors with two fan blocks and separate start, this allows you to use different level power. High-quality models of convectors can be used in the bedroom and children's room without fear.
A common mistake is installing an in-floor convector close to French glazing. A gap of approximately 25 cm should be created so that the air flow spreads upward along the structure without being reflected from it. Not worth it for a long time keep the opening above the convector open, using it as a thermal curtain if it is severely frosty outside.
The greatest effect from the convector circuit is achieved when used together with emitters - radiators and a heated floor system. This is especially true for underfloor heating in areas where there are severe frosts in winter.
The two most common mistakes when installing convectors are installing a floor-standing unit on an unprepared surface and incorrectly calculating the dimensions of the recess for an in-floor convector. In the first case, you risk getting an unstable structure, knocking over the device and breaking the pipes. In the second case, part of the housing will stick out above the floor, or the convector will “fall” into the floor, and this will create difficulties with its connection.

It is very risky to undertake the installation of a convector system yourself, without skills. You should not buy appliances without preliminary calculations and a heating system design. If you have Russian convectors, you need to focus on them, since they are adapted to local conditions and meet the standards of common heating systems in terms of pressure, temperature and connection method.

Water heating convectors are becoming more and more common today. Besides the fact that they are more effective standard options heating, they have a presentable appearance and reasonable cost. In stores, there are increasingly devices that are completely different from the usual ones.

Functions

The essence of convection is the distribution of heat from a heating device through the air. According to all known laws of physics, heated air rises from the radiator and mixes with cold air, after which it cools and returns. The process is constantly repeated and maintains the established temperature regime in the room. While the wall convector is operating, a stable process of air mass exchange occurs.

Previously, there was a fairly large temperature difference in the lower and upper parts of the room when using such systems. AND? Thanks to the efforts of designers who tried to create a new device that would reduce this difference, such a device arose. It is assigned the following functions:

complete cutting off of cold air flows from window openings;
creating a comfortable temperature regime in room;
preventing condensation on glass;
uniform and efficient heating of the entire volume of the room.

If you pay attention to the structural elements of the device, it will become clear that it has a fundamental difference with a radiator.

Advantages

Water ones (made in Russia) can be used in premises for any purpose, despite their small dimensions and original design. The design is extremely simple, which ensures ease of installation and maintenance, and their cost is lower compared to conventional radiators.

The air in the room is uniformly heated with low coolant consumption, which makes it possible to save money. It is possible to create a coherent scheme by combining several convectors to provide uniform heat throughout the entire house.

The temperature range near the ceiling and floor does not exceed two degrees. This indicator for a traditional radiator is about +7C.

The convector, whose average price is 3 thousand rubles, has a built-in special heat sensor and thermostat, due to which the quality of the device’s operation is improved. Maximum level heating in some options can reach +80C, but few people need such a temperature.

The device is completely safe for small children, since it is impossible to get burned on it, regardless of its location.

Varieties

Water convectors are divided according to the following indicators:

fastening method and location option in the room;
the type of convection used, divided into tiers;
availability of additional devices for regulation and control;
design;
power that increases with increasing device dimensions;
height of the device.

On modern market The most widespread type is the wall-mounted water heating convector, which has forced and natural air circulation. In the latter option, the air flow, in accordance with physical laws, itself enters heating elements, thus ensuring natural circulation.

Another type is represented by devices with fans built into the design. They provide an increase in the total volume of air entering the heating device. This improves the quality of the system itself. Safe operation is guaranteed by the voltage required to operate the fans, which is 12 volts.

Wall devices

Due to their light weight, installation of this type of convectors is possible on any wall structures. Even a thin, small partition made of single-layer plasterboard material can easily bear such a load.

Wall units are compact in size, and when installed under window openings, they are as good as any heating battery, since the unit has sufficient power due to the high speed of coolant movement. The design of such models usually includes special fins to increase heat transfer.

The Ballu home convector has the possibility of both wall and floor installation. Among the advantages, it is worth noting the presence of a remote control, special wheels for easy movement, as well as a frost protection function and automatic shutdown when overheating. According to customer reviews, such a device is excellent for heating bathrooms and is completely safe for children, since, due to the use of glass ceramics, the front side hardly heats up.

Built-in models

This new approach solves two problems at once - design and heating. Installation requires some construction work so that the device is not so noticeable. It is possible to construct small niches under the windows or install special channels in the floor. In any case, the prepared structures hide the parts of the convector.

Correct determination of the power required to heat a space of any size will allow you to form effective system, which will work regardless of environmental conditions. For example, large gyms or swimming pools can be heated in this way.

Built-in water heating convectors Itermic ITTL have minimal dimensions and are based on the principle of natural air flow, due to the temperature difference between cooled and heated air. Most buyers noted the high-quality assembly of the convector, silent operation, which is especially important at night, and the absence of the need to use a humidifier, since the device does not dry the air.

Floor convectors

The fastening method is main feature such devices. They are not installed on the walls and other structures of the house, but are mounted anywhere on the floor - mainly next to the front door or under the window.

Floor convectors have practically no external differences from wall version. The same significant heat transfer power with a small amount of coolant used, non-standard shape and small dimensions. The installation method is the only difference. Instead of brackets, the structure is equipped with special stands.

The Electrolux ECH floor-standing device has a moisture-proof housing and a multi-stage air purification system. Based on consumer reviews, it is worth noting the quick heating of a medium-sized room and the intuitive display. Among the shortcomings, most highlighted the too bright backlight of the screen and the smell when turned on for the first time.

How to choose

First of all, you need to pay attention to power indicators. They are the same for all options and amount to 1 kW per 10 sq. m of space, while the ceiling height should be no more than 3 meters. For each window opening in the room, 0.2 kW is added. This rule does not apply to continuous glazing. When choosing a more powerful convector, the price will be higher than average and will be approximately 5-7 thousand rubles.

For a unit with installed fan, space is provided for mounting a step-down transformer device and the possibility of connecting to the electrical network alternating current. It is recommended to prepare a special place for the transformer next to the convector.

It is necessary to pay attention to the height of the device Special attention. When installing in a floor niche, you must first compare its dimensions with the dimensions of the channel. The average parameter is about 30 cm. The material used to make the case also plays a role. The floor-mounted box must be made of high-quality anti-corrosion alloys.

Wall-mounted water heating convector: design

The basis of the device is a heat exchanger; in addition to it, the design includes a casing and additional elements. The heat exchanger consists of copper tubes with coolant moving through them. Aluminum fins are attached to them, which improves the quality of heat transfer. The distance between them has a direct impact on work efficiency - it should be of medium size. The number of ribs also plays a role, but not as important as the free space between them.

For built-in options, an addition is used in the form of decorative grilles used to hide the device. The choice of grille is of particular importance - in order not to interfere with the outgoing warm air flow, it must contain cracks or holes with large area.

The valve is a mandatory component; it has a direct connection with the thermostat and is used to regulate the degree of heat transfer. It is possible to add an air vent to the design. The power of the unit is also regulated by installing additional heat exchangers.

Each part of the convector is made of metal with a high degree of heat transfer to increase efficiency and reduce the time required to heat the device. It is worth noting that there are two connection options - end and side.

Installation features

If a convector for a summer residence is connected to a common heating system, installation should be carried out taking into account the nearest location of the heat exchanger. At the bottom of the case you can find special adjustment bolts. They are used to align the unit in horizontal level and height.

If it is necessary to use it as a thermal curtain, the box should be as close as possible to the window opening.

Conclusion

Modern heating techniques are quickly gaining the attention of consumers. The thing is that today when using utility networks key point became the economic side. Therefore, devices being developed that allow saving on heating costs are always of interest. A wall-mounted water heating convector falls into this category.

Installation of wall and floor options is possible for anyone who has dealt with plumbing fixtures.

Increasingly, owners of private houses in in Instead of conventional radiators, convectors are chosen for heating residential premises. These heating devices can have a very diverse appearance and different designs, depending on the location and characteristics of the operational purpose.

A water heating convector is perfect for exquisite interiors, in which the central composition is a wall with panoramic glazing. If an ordinary battery, even one with the most elegant appearance, is not in all cases able to fit into decorative design living room or hall, then the convector can become completely invisible or ideally complement the style of the interior, without losing any of its qualities, exactly how heating device.

Functions of water convectors

The convector is able to create maximum protection against cold flows coming from window openings and entrance doors. This happens thanks to the powerful thermal curtain created by this element, which almost completely blocks the access of cold masses.

The convector is guaranteed to create desired temperature air, comfortable conditions for living or working in the room in which it is installed.
The ability to create, quickly and evenly distribute heat throughout the entire volume of the room, thanks to the movement of warm air, sometimes makes a convector simply irreplaceable for some large rooms.
The convector perfectly resists condensation on windows or slope walls. This means that the glass will remain transparent and not frozen even in severe frosts outside, and the slopes will not become damp, that is, the threat of mold spots appearing on them is minimized.

Basic convector design

The word "convection" comes from the Latin " convectiō" - transfer. In the case being considered now, this is the transfer of heated air in streams or jets that emanate from a pipe with a heat exchanger, passing through the body of the device, while gaining speed and power, and then receiving final directionality on the grille, which often has adjustable blinds.

Directed heat, according to all the laws of physics, quickly rises to the ceiling, creating a curtain of cold coming from windows or doors, and creating convection movement of air in the room. Then, cooling down, the air falls down again to heat up again and continue its cyclic movement. It is this constant air circulation that allows you to maintain almost the same temperature, with a difference of only 1-2 degrees under the ceiling and near the floor surface.

The design of a conventional convector is very simple

The design of a water convector is quite simple and to some extent resembles a conventional battery, but the principle of its operation is somewhat different from the latter. If from a conventional battery, not equipped with special convection channels, heat emanates from the entire surface, and it is directed predominantly in only one direction, that is, direct thermal radiation predominates, then the convector, as it were, passes cold air through itself, warming it and directing it to the ceiling.

Built-in convector Techno

The convector fundamentally includes a pipe (in modern models, most often copper), which is surrounded by metal heat exchange plates that are in direct contact with it. — these elements are the core of the convector. The more such plates in the device, the higher the level of heat transfer. The pipe with the heat exchanger is located in a special housing, which has an exit window in its upper part, covered with a grille or directionally controlled blinds.

Modern models equipped with a thermostatic regulator, which allows you to maintain the desired air temperature in the room. In addition, the design usually includes a valve for releasing air.

To increase the power of the convector, two or even three heat exchangers can be installed in its body. And some convectors also have a built-in fan - this allows, in some cases, if necessary, to warm up the room much faster.

Advantages and disadvantages of water heating convectors

Like each of the existing heating devices, convectors also have their pros and cons, which you need to know about before purchasing and installing them.

TO positive The criteria for using this type of device include the following:

The efficiency of a convector in uniform heating of rooms using air circulation.
Very rapid spread of heat, but how the result is heating rooms.
Saving energy resources, as for heating system you don’t need a large amount of coolant or its strong heating - usually a temperature of no higher than 60 degrees is sufficient.
The compactness and lightness of the design facilitates the installation of convectors. If desired, models can be used that will save “precious” space in the room.
Powerful convection currents and thermal curtains prevent the formation of condensation on the surfaces of windows and in the corners of rooms.
Elegant modern look, allows you to “fit” the heating device into any interior style.
The convector also has the advantage over some modern radiators that it has the ability to heat the coolant to critical levels of -90 degrees, while for a battery I often have an upper “threshold” of 60-70 degrees. This parameter is especially attractive for installing such heating in houses located in regions with harsh winter climates.
At the same time, it is very difficult to get burned on the convector, since the most heat– on pipes that are hidden in a special box and are also protected “ shell“heat exchange plates. This factor is especially important for families with small children.
Another clear advantage of this heating device is that it does not dry out the air much - this occurs due to constant circulation and enrichment with moisture. To increase, if necessary, the humidity in the room, a container of water can be installed on the convector. Some models already have such a capacity in their design.

TO shortcomings The performance characteristics of convectors include the following:

If the heating system is built on convectors, then the rooms need to be cleaned quite often. wet cleaning. This is due to the fact that dust will constantly rise up along with the heated air masses. which means the dust level in the air will increase.
Not all people like constantly circulating air currents, especially along the floor, when cooled air returns to the heater. It turns out something like a constant light draft.
Convectors are not very effective for organizing heating in rooms with high ceilings, since the air has to make an excessively large circulation revolution, and at the same time the volume of the room will not have time to fully warm up. True, there is a way out - but you will have to purchase convectors with several heat exchangers in order to increase the total active heat exchange area.
A heating system can only be effective if natural ventilation. If forced force is used in a house or apartment ventilation diagram, then warm air will simply be removed from the premises, and the heating efficiency will sharply decrease.

Classification of water heating convectors

As mentioned above, water convectors are produced providing exclusively natural circulation heated air, and having the ability to switch to forced flow mode. Devices with natural circulation are marked KVE, and those with a forced system - KVP.

In the first version, warm flows rise up, and the cold ones, falling, fall back into the convector solely due to the difference in air density at different heating temperatures, that is the entire cyclic process is carried out naturally.

In the second case, the speed of air flow circulation can be enhanced by the influence of the elements built into the design of the device. electric fans. The overall spread of heat throughout the room occurs much faster due to the increased intensity of air movement, which means it will take less time to provide a comfortable microclimate in the room. The fans in such devices operate on a voltage of only 12 volts, which ensures complete safety during operation, wherever they are installed.

In addition, convectors are divided according to the following parameters:

Devices may have different sizes in height, width and length.
Convectors can have different thermal power, which will depend on the size, volume and number of heat exchangers.
Convectors can differ significantly in their design layout, which often depends to a large extent on the location of the typical installation.
The difference may be the presence or absence additional elements control, adjustment, management, to the degree of automation of the device.

Types of convectors by installation method

As mentioned above, convectors are divided according to the place of their installation. They are wall-mounted, floor-mounted and built-in.

Wall-mounted water convectors

Wall convectors are hung on special brackets fixed to the wall. They are light in weight, so their installation is quite easy. The big advantage of this type of convectors, in contrast to , is the fact that due to their small mass (both their own and the coolant circulating through them), they can even be attached to plasterboard partitions.

An example of using two types of heating convectors - wall-mounted and hidden in-floor at the entrance

If necessary, you can choose a narrow, compact device that will protrude from the wall by only 80-100 mm - this is especially important if the room has a very large limited area. In this case, the required power can be compensated by the height or length of this element of the heating system, that is, by increasing the active heat exchange area.

Floor radiators

A floor convector is not much different from the design of a wall convector. It is also enclosed in a lightweight casing, has all the elements necessary for adjustment, but, in addition, is equipped with reliable legs for installation and permanently securing it to the floor.

Floor options, as a rule, are designed for a low level of thermal power, so any objects can be placed on them for drying or light heating.

Despite the compactness and squat nature of such devices, they have excellent heat transfer, so they can be used as the main source of heat in rooms.

In spacious rooms with panoramic glazed walls, such convectors are often installed as additional heating devices. They are placed along the glazed wall, which avoids fogging, since the constant circulation of warm air dries the glass.

Built-in convectors

Built-in heating convectors are suitable for any interior, both modern and retro styles. This type of device must be provided with a niche in the floor, so its body is installed during floor insulation work and raised to a certain height. As a result, the convector grille should be flush with the surface of the finishing floor covering.

Such models of convectors, depending on the power and the number of hidden devices installed, are capable of heating not only small room, but also spacious areas of halls and halls, especially when they are equipped with a forced air circulation system. Very often they are used in buildings with a large area of glass walls, for example, in swimming pools, gyms, shopping malls, winter gardens and other similar structures.

A built-in convector can be placed not only in the floor structure, but also in the window sill, if you choose the right size.

Gratings for closing the outlet channel are often given original design. They can be a solid rigid part or be arranged according to roll type- roll up if necessary.

Criteria for choosing a water heating convector

There are several criteria that you need to pay special attention to when choosing water heating convectors for your home:

Thermal power indicator. Usually the norm is 1 kW per 10 sq. m of room area (with a ceiling height of no more than three meters). However, it should be noted that this is only true for “ideal” conditions with the most effective thermal insulation, which is, in principle, unattainable. There is always heat loss - windows contribute to this, for example. For each window, even the highest quality, with double-glazed windows, you need to add another 0.2 kW.

The power of a particular device depends on its dimensions, the number of pipes placed in it and, accordingly, the total area of active heat exchange. The variety of models allows you to make the right choice - both compact convectors with a power of several hundred watts and large-sized products capable of delivering up to several kilowatts are on sale.

Unlike conventional batteries, the convector will not allow you to change the thermal power in one direction or another by adding or removing sections. This imposes special requirements to initially the right choice the required device.

You must immediately select a model of the required size and power - the range of these parameters is very wide

In order for convector heating to be effective in non-standard, extensive or panoramic glazing walls make more complex calculations which are produced by specialists.

If you select a convector with forced circulation air, which is carried out using a fan, it is necessary to think in advance about how to connect it to the power supply. In addition, you will have to foresee in advance the installation location of the transformer, which will convert the alternating mains voltage of 200 V into the required operating 12 V.
The dimensions of the convector are important when choosing any type of device. Therefore, you need to take measurements from the place where you plan to install it - hanging on the wall, installing it on the floor or hidden installation.

If you choose an option that is built into the thickness of the floor, then you need to provide for the possibility of raising the floor to a certain height or preparing a recess so that the convector body stands at the required depth. In the event that you plan to install in-floor appliances into a ready-made, covered floor, it is necessary to find out in advance the depth of the existing underground space.

The modern method of heating using water convectors is becoming increasingly popular. It is used both as the main and additional source heat, adding to common system at home, which significantly increases its efficiency. The main thing is to choose really high-quality models that meet the parameters of heated premises, produced by well-known domestic or foreign companies and have proper certification, reliable technical documentation and, of course, a manufacturer’s warranty.

When calculating the power of heating systems in a private home, certain difficulties often arise. Difficulties bring glass doors, leading to glazed loggias and balconies, as well as French windows. In such conditions, it is possible to place traditional heating radiators not under the window, as is customary, but only on the side wall. This method of placing the radiator significantly reduces the quality of the heating system, since maximum efficiency achieved by installing batteries in the coldest place in the room. In addition, this placement of the radiator limits the free space of the room.

Of course, you can resort to using a heated floor, but when installing it, it is not always possible to achieve the desired degree of heat transfer. You should not discount such factors as the cost of heating and the possibility of combining it with flooring - heated floors are not recommended for use in rooms where wood, which has high thermal insulation properties, is used as a covering. In this case, it will be more effective to use in-floor water heating convectors, mounted in the floor and covered with a decorative grille on top.

The operation of an underfloor heating system is characterized by the following positive aspects:

Heat is supplied directly to where the greatest heat loss is noted;
Access to the loggia door and windows is not limited;
The free space of the room and the possibility of making design decisions increases.

The in-floor convector https://grostal.ru/konvektory-otopleniya/specialnye-konvektory/ can successfully replace a traditional wall-mounted heating radiator. What is this convector?

This is a device consisting of a housing (trough, channel) made of various materials. Most often, stainless or galvanized steel, which has increased resistance to corrosion, is used to make the body of an in-floor convector.

A heat exchanger is built into the housing, for the manufacture of which it is used copper tube, curved in the shape of a horseshoe. The surface area of the heat exchanger is increased by aluminum fins. A decorative grille is placed over the device, for the manufacture of which the following materials can be used:

Wood (various species);
Steel;
Aluminum.

The performance of the convector depends on the temperature of the supplied coolant and the intensity of the air flow created around the heat exchanger. Convectors can be used in various systems heating systems operating in a wide range of coolant temperatures - from 45 to 90°C.

To increase productivity and heat transfer rate, a tangential fan is built into the convector, providing increased air flow intensity. Before every start heating season The underfloor heating convector should be cleaned of accumulated dust and debris.

Convectors got their name based on the transfer of heat through convection. When cold air passes around the convector heat exchanger, its temperature rises against the background of a decrease in density, due to which the air rises and enters the room through the decorative grille that covers the working channel. The place of the rising air is taken by air from the room with a lower temperature and the work continues.

Power selection

Selecting the heat transfer of an in-floor convector is no different from calculating the heat transfer of a traditional radiator. The number of convectors and their sizes are determined by the heat demand, which is calculated when designing the heating system, taking into account all possible heat losses.

Trench convectors can be used in heating systems with standard parameters intended for panel radiators– pressure up to 1 MPa and coolant temperature up to 90°C.

Power adjustment

Shut-off and control equipment in the form of ball valves, manual valves and automatic thermostats is installed on the connections to the in-floor convector.

Ball valve

When using a ball valve as a shut-off and control valve, there are advantages and disadvantages.

The advantages include the simplicity and high degree of reliability of the design, small dimensions, the ability to maintain the cross-section of the valves and ease of operation.

The disadvantages are determined by the very possibility of the ball valve:

Operation is ensured only in the “closed” and “open” positions. When installing the valve in an intermediate position, the likelihood of loss of tightness increases.
When the ball valve is suddenly opened at the moment of connection to the system, a hydraulic shock occurs, which reduces the strength of the heating device, which can cause failure of the in-floor convector.

Manual valve

The advantages of manual valves include:

Ensuring smooth connection to the heating system;
Security high precision adjusting the heat transfer of the convector.

The disadvantages of manual valves appear in the form of:

Inconveniences in regulating the operation of the convector;
Reduced throughput.

The main disadvantages of ball valves and cone valves are that the power of the in-floor convector is regulated according to manual mode, that is, it requires constant presence and attention from the owner.

Thermostat with remote sensor

As an alternative, to regulate the temperature of the room, you can use an external thermostat equipped with a capillary tube 2 or 5 m long. To ensure integrity, the capillary tube should be laid inside a protective one.

Such a device ensures stable and reliable operation with a significant reduction in energy costs, achieved through automatic control of heat transfer.

Thermostat with servo drive

A servo drive is a fairly stable operating element, verified for resistance to radio interference. Its operation is almost silent, and in the absence of current, the servo drive is in a closed state.

Ease of use with a trench convector is determined by the compactness of the servo drive and ensuring uniform opening and closing. When using an appropriate thermostat, the principle of automatically maintaining the temperature in the room within a given range is ensured. Thermostats are ideal for controlling the operation of any servo drive.

Connection room thermostats made directly to one of the convector modules. Depending on the manufacturer and methods of operation, installation of the servo drive can be external or internal (directly into the convector).

Rational use

This issue should be addressed at the design stage of heating systems. Attention should be paid to the correct calculation of the required floor thickness taking into account the installation of the convector. It should be taken into account that at the place where the convector is installed, it may be necessary to strengthen the strength of the ceiling. Do not forget that the performance of the convector directly depends on the depth.

When designing a heating system, it is necessary to correctly place the supply and return pipes, and also provide for draining water and pumping the system in case of air ingress. This is also important because in-floor convectors operate on a different plane, unlike traditional radiators.

Such a convector also has a completely different resistance to coolant flow. Accordingly, before selecting a convector, it is necessary to perform a hydraulic calculation of the system and first select settings for thermostatic valves. Due to the imbalance of the system, heated water will not be able to enter the convector in sufficient volume, which is why the operation of the heating system will be ineffective.

Often installed on duct convectors thermostatic valves with an integrated temperature sensor, which allows for remote monitoring.

Installation niche

A niche located in the floor is necessary for correct placement And efficient work in-floor convector. It needs to be prepared at the design stage, because it is easier to leave a void while pouring the base than to cut the concrete later and risk the integrity of the base. Although in finished floor you can make a niche of appropriate sizes, however this work should be performed with extreme care so as not to damage the waterproofing layer.

If it is necessary to install the convector in the ceiling (between floors or above the basement), then it should be lowered. The finishing method is determined by the direction load-bearing beams and type of ceiling.

When placing the device along the beams, the work of constructing a niche is greatly simplified. When constructing a niche, you should consider how to install a decorative grille - the easiest way is to trim the edges of the niche with a steel or aluminum corner.

Simultaneous use with heated floors

In rooms with significant heat loss, the surface for installing heated floors may be limited. In such cases, trench convectors are used as an addition to warm floor. Stable joint operation of panel radiators, heated floors and duct convectors is ensured by the installation of additional automation components.

Duct convector maintenance

Convection is based on the movement of air masses, which contributes to the accumulation of a significant amount of dust around the convector. In-floor convectors are more susceptible to this negative property, since they are located in a recess (niche), which in itself contributes to the accumulation of dust.

Often, convectors are installed in front of the door leading to the balcony or terrace, and in warm seasons the doors are constantly open, which allows dust to enter from the street. That is why the convector should be cleaned at least once a year before starting the heating system.

The convector channel is best cleaned using a vacuum cleaner. If during the design you provide for the installation of roll-up grilles, then access to the convector can be greatly simplified.

To summarize, we can say that trench convectors are great way organizing space heating in the following cases:

When there is no space to install traditional heating radiators;
There is not enough area to install heated floors;
The floor covering does not allow efficient use of the underfloor heating system.

Gas convectors are very popular because they are very reliable and practical to use, and their maintenance does not take much time or financial investment. Most breakdowns are the failure of a thermostat or thermocouple. You will learn how to replace a thermostat in our master class.

Troubleshooting

If the thermostat does not click when switching, if the convector turns on and heats up, but burns at maximum and does not respond to turning the temperature control button, there is only one conclusion: the thermostat is faulty and needs to be replaced. Repairing the thermostat is impractical, and you can buy this part for the convector at any hardware or specialty store.

Preparing for work

To replace the thermostat you will need the following tools:

Phillips screwdriver;
flat screwdriver;
new thermostat;
gas leak test brush.

Execution of work

We shut off the gas supply to the convector. Unscrew the fastening screw with a Phillips screwdriver and remove the gas valve body.

This is what the top part of the installed thermostat and the convector temperature control button look like.

Using a flat screwdriver, unscrew the temperature control button.

Unscrew the regulator bolt and remove the upper part of the thermostat.

The lower part of the thermostat (cone) is attached behind the convector body; remove it.

We install the new thermostat in place. First the top.

We tighten the bolt of the regulator, securing the upper part of the thermostat until it stops, this will be the maximum temperature at the regulator button.

Insert the button and scroll it clockwise until it stops. We tighten the fastening bolt. Place the top cover of the button with the number 7 in the upper position.

Place the gas valve body in place and tighten the mounting screw. We insert the lower part of the thermostat (cone) into the mounts on the back of the convector.

Open the gas supply valve to the convector. To prevent gas leaks, it is necessary to check the junction of the gas hose with the pipe and the convector with a brush and soap solution. The absence of bubbles means the connections are tight.

Turn on the convector, turn the control button to maximum, then to a lower value, there should be a click and the main flame should go out. This means that the room temperature is higher than the value on the adjustment button. The thermostat is working.
