Connecting VITRON convectors. Regulation

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

Typical mistakes when installing convectors are 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 their small size does not allow them to achieve high efficiency.

Typical questions about heating with convectors

We are interested 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 output of a heating device is design parameter, which 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 are talking about the sound made by fans, then you should choose a device with speed control. There are convectors with two fan blocks and separate start, this allows you to use different power levels. 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 devices without preliminary calculation and 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.

When planning to create heating in our home, we want it to be economical and efficient. Convector heating has precisely these characteristics - it is based on convectors powered by bottled or main gas, water systems or from electrical outlet. Let's see what convectors are, how they work and how they differ from each other. We will also look at the main features of convector heating of residential premises.

What is convection

Convective heating uses the simplest laws of physics, according to which heated air becomes lighter and rises. Every heating convector is built on this principle, regardless of what it is powered from. As practice shows, this scheme is highly effective - residential premises become warm, and relatively quickly.

Convector heating allows you to heat rooms for any purpose - these can be living rooms, children's rooms, corridors and foyers, kitchen areas, bathrooms and toilets, covered balconies and loggias. It heats using heated air, quickly saturating the heated rooms with heat. Let's see how the warming up process occurs:

All convectors work on the same principle - they create air circulation in the room, gradually warming it up.

Possessing large area work surface, a heating element heats the air around it;
Warm air masses rise upward, leaving the equipment (or simply going upward if convector-type heating radiators are used);
Cold air masses replace the air that has gone up.

The process is repeated until convector heating warms up all the air in the rooms.

Heating elements can operate from electrical network or by burning gas fuel. Convector-type heating batteries operate due to the coolant entering them. By the way, the batteries do not have housings, unlike the same electric and gas convectors. But their operating principle is similar - heating is carried out due to the heating air, and the thermal radiation from them is very weak.

Advantages and disadvantages of convector heating

Let's take a look at what the main advantages of convector heating are and try to present all the advantages in the form of a list:

Installation of electric convectors is one of the most quick ways organize constant heating of a private home.

Possibility of heating premises for any purpose;
No impact on air (convector heating does not burn oxygen);
Low impact on air humidity;
Ease of installation of equipment (typical for electrical appliances);
Absence negative influence for your well-being(this is how a convector differs favorably from an IR heater);
Large selection of heating equipment.

There are also certain disadvantages:

Convector heating has little effect on air humidity. However, this is typical for many heating devices;
Some people don't like the feeling of overheated air;
Low efficiency in rooms with high ceilings;
High temperature difference in the lower and upper parts of the rooms.

If we take into account electric convector heating, it is characterized by another disadvantage - high cost. But if the house does not have a gas main, and you want the heating system to be inexpensive and easy to install, then you cannot do without convectors.

Types of convectors

Let's see what you need to create convector heating in your home. The finished system can be:

Water - using convector heating radiators, with pipes and a boiler (electric, gas, solid fuel or liquid);
Electric – here we mean the installation of electric convectors;
Gas - special gas convectors are installed in the rooms, most often powered by bottled gas.

Let's talk about these convectors in more detail and find out distinctive features certain convector heating systems.

Convector heating radiators

Many people remain committed classical systems heating, laying pipes in houses and installing boilers. If there is gas in the house, then this is even a plus - after all water heating, built on the basis gas boiler, is the most inexpensive and economical. Approximately the same can be said with regard to heating based on boilers running on liquefied gas. The next leader in terms of efficiency is solid fuel equipment.

Solid fuel boilers can work completely free of charge if you prepare firewood in advance from the nearest forest. If there are no clearings nearby, you can limit yourself to purchasing fuel in bulk - it will be cheaper.

Convector water heating involves the use of radiators connected to pipes laid throughout the house. The hot coolant entering the batteries heats up the metal, after which the heat is transferred to the surrounding air. It rises up, and cold air masses take its place. Temperature control in such heating systems is carried out in general procedure(regulated by the boiler) or privately (using taps and valves on batteries).

Considering the complexity of conducting installation work, we recommend the use of water convector heating in buildings with a large number of rooms - here the installation of dozens of autonomous electric convectors is not justified. It is also recommended for homeowners connected to gas mains and those who have access to inexpensive solid fuel.

Electric convectors

It is very easy to build convector heating based on simple electric convectors. The entire installation process boils down to the following steps:

Brackets are mounted on the wall;
Convectors are hung on brackets;
The equipment is connected to the electrical network.

If in front of us is a miniature country house with one room, then installation work will take a maximum of half an hour - it is more difficult to extend an outlet to the installation site than to connect a convective device.

Electric convectors work from the mains. Unlike the convector heating batteries described above, they do not contain coolant or any other liquids. Heating here is carried out by finned heating elements installed in the lower part of the heating devices. Air is taken in through the lower slot openings and removed through the upper ones.

The operation of convector heating is controlled by automation - it can be mechanical or electronic. Mechanical thermostats operate on the principle of a bimetallic plate. As soon as the temperature reaches the set value, the plate will bend and open the contact groups. If the air cools down, the opposite will happen - the contacts will close and the heating element will continue to operate. Here it is not the temperature that is set, but the degree of heating (for example, using numbers from 0 to 9).

Electronic thermostats are built on the basis of control modules with sensors, microcircuits and other electronics. They carefully control the air temperature, giving commands to turn the heating elements on/off. This work scheme has the following advantages:

Convectors receive additional functionality - timers, anti-freeze, program operation, etc.;
Economical – electronic convectors provide up to 5-10% energy savings;
Ease of creation comfortable atmosphere– the temperature can be adjusted with an accuracy of 0.5-1 degrees.

Convector heating based on electric convectors is recommended for use in small and medium-sized non-gas houses. Its main disadvantage is its high cost - you will have to pay several thousand rubles to heat even the smallest house for a month.

Gas convectors

We come to the last equipment from our review - gas convectors. They can operate on both main and liquefied gas. The principle of their operation is very simple:

A gas burner burns gas to produce heat;
Under the influence of the flame, the metal radiator begins to heat up;
The ribbed radiator begins to heat the air;
Then the simplest convection works - we considered this principle at the very beginning of the review.

Convector heating based on a gas convector cannot be called the most common heating approach residential buildings. Rather, this is the rarest option, since such units are not widespread.

Used in such devices gas-burner requires removal of combustion products - for this they are equipped coaxial chimneys, leading directly beyond the wall. Accordingly, there are as many chimneys as there are devices in the house. This approach cannot be called optimal, but if the task is to heat a small country house or country house with 1-2 rooms, then it will best option. For heating big houses such equipment is not suitable.

The most commonly used fuel here is liquefied gas, connected via flexible hose. If convector heating involves the installation of several gas appliances, we recommend laying a small gas line above the floors to distribute fuel to all convectors. This scheme will allow you to power several gas appliances from one cylinder.

Buying an in-floor convector is a responsible and expensive business; customers want to know in advance what problems they will encounter when the time comes to install an in-floor convector in their apartment or private house, we will describe the main points of installing these batteries, a feature of which is installation in the floor.

The first task for installing an in-floor convector is preparing a niche in the floor. Also, convectors that are planned to be hidden in the floor can be mounted in a false floor, that is, not in concrete screed, and for example on a wooden podium. In this case, the convector must be secured using adjusting bolts and anchors.

Let's take the most common type of installation of an in-floor battery, this is in a concrete screed. In order for the convector to be installed correctly and without problems, it is necessary to create a niche for it.

Recommendation 1: Niche for convector | Manufacturers recommend make a niche in depth plus 10-20 mm from full height convector, in order to level the convector using adjusting bolts and dock beautifully flooring(laminate tiles, parquet) with convector box. P about width and length - plus 5-10 cm from the full width of the convector box, in order to be able to firmly secure the box using anchor bolts and cement mortar.
Installation dimensions of the niche for the convector: Depth +10 mm | Width +10-15 cm | Length +5-10 cm

The location of the in-floor convector to a window with natural convection is universal, the convector can be connected to the left side and to the right side, it can simply be turned around, since the heat exchanger is located in the middle. If the heat exchanger is closer to the edge of the convector, then place it so that the heat exchanger is closer to the room.

The location of an in-floor convector to a window with forced convection is considered by default to be a left-side connection; if the convector needs to be connected to the right, this must be indicated in the order when purchasing. At the manufacturer's factory, exits are made for the right side.

Recommendation 2: Spaces from windows and walls | Recommended dimensions for the location of the in-floor convector relative to the room itself and panoramic window where it will be installed. Manufacturers recommend retreat from the window 5-15 cm for efficient circulation of cold and heated air, indentations to the left and right of the walls, if there are any, are 15-30 cm. so as not to expose wall coverings (wallpaper, plaster, etc.) to heat and, of course, for ease of battery installation.
Location of the convector relative to the room and window: Distance from the window 5-15 cm | distance from the side walls 15-30 cm

Recommendation 3: Curtains | There are cases when powerful curtains and curtains stand in the way of the convector, then what is better to install before or after? None of the manufacturers answer this question, so we use the recommended sizes. It is impossible for an in-floor convector to adapt to the curtains, since nothing good will come of this; the curtains must adapt to the convector. The convector should blow through the window, remove condensation and act as a thermal curtain from the cold air flow. Here are a couple of options to resolve the issues.

Recommendation 4: Isolation| The installer must then form the layers correctly additional protection convector from the floor and reduce heat loss due to insulation, including organizing noise insulation, you can familiarize yourself with these recommendations in this example (photo No. 1). But all these measures are not mandatory, these are recommended actions (photo No. 2) for more efficient work and operating a convector in the floor, we know from practice that many installers don’t bother and simply fill it with screed and concrete. So, when we have made a niche for the purchased convector, installed it correctly, covered it with insulating layers, filled it with concrete, we need to connect it to the heating system. There are several options for the heating system:

Connecting a floor convector to the heating system

System automatic adjustment A convector without a fan is not always effective, since it is necessary to strictly follow the instructions stated by the manufacturer, otherwise the automation will not effectively regulate the convector.

The regulator measures the room temperature using a built-in sensor and maintains the set temperature value. When the room temperature drops below the set value on the thermostat, the thermal servomotor will open the valve. The room temperature controller should be positioned in such a way that the temperature measurement is as accurate as possible, without affecting solar radiation or sources of heat and cold. Installation should be carried out at a height of about 1.5 m above the floor. It is prohibited to install a thermal head in the floor convector itself.

Trench convectors electrical connection

If you have a convector with a fan, then you additionally need to connect electricity to the convector to be able to control the fans. For each convector, an additional convector module is purchased, popularly called a transformer, where you need to supply 220 V, and from it either 220 V goes to the fans or 12 V, depending on the manufacturer. This module also controls the room thermostat and vice versa. The thermostat automatically commands the fan to turn on if the room temperature drops below the set point on the thermostat. A room thermostat measures the temperature in the room using a built-in sensor and maintains its value at a set value. In parallel with this, room regulator can control servos and also regulate fan speed. You can read about this in article about managing in-floor convectors.

If you absolutely do not want the convector module to be outside the convector, then you can consider Verano, their modules are mounted directly into the convector box.

On the trail. In the screenshots, you can clearly see several connection diagrams for the electrical part of the in-floor convector. These diagrams are visual and are used for different manufacturers floor convectors, it is mandatory to coordinate the diagram with an electrician or our specialist. Each manufacturer has its own modules and its own recommended room thermostats, so you must base it on the manufacturer. You can request an exact diagram from our specialists, who will provide it to you.

Installation of decorative grilles and frames

The final element of the trench convector is the elegant grille. It can be without a frame, or with a frame (U-shaped and F-shaped). Wooden grates can be made exclusively from natural wood. To protect grilles made of wood, it is recommended to use staining and varnishing. Aluminum grilles are more wear-resistant, as they are made of aluminum and undergo an anodizing process. Customers often ask which grating is more durable; in fact, all gratings are durable, both wooden and aluminum, and can withstand loads of 40 kg or more. one bar. The only point is that wood is more susceptible to external wear, that is, abrasions from walking on it will be more visible, and it is more easily soiled since it is wood.

All manufacturers additionally offer a convector option with a decorative frame, a frame, in order to close the joints between the floor covering and the convector itself in the floor. As with everything, there are advantages and disadvantages. The advantage of using a decorative frame in a convector is the closing of the joints; often tilers do not perfectly fit the tiles to the convector, leaving gaps and cracks. That's when framing helps. There are two types, U-shaped and F-shaped. The U-shaped one is less noticeable, since it does not lie on the floor covering, while the F-shaped one lies on top, has a width of 1-2 mm, thereby completely hiding the joint between the convector and the floor. But in this case, the grate is slightly higher than the floor, that is, a slight rise is formed. If without a frame, then the floor, convector and grille are on the same level.

The cost of installation and installation of an in-floor convector is approximately $100. USA, depending on the complexity of the work, which is assessed by the installer.

Video installation and in-floor convector

On the Internet every time more and more more videos videos about the installation and connection of trench convectors, we have selected the most informative and understandable ones at the moment. Enjoy watching.

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. IN 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 a copper tube bent in the shape of a horseshoe is used. 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 designed 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;
Ensuring high accuracy of convector heat transfer adjustment.

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 adjusted manually, that is, it requires constant presence and attention from the owner.

Thermostat with remote sensor

As an alternative for making adjustments temperature regime 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 that has been tested 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 correctness of the calculation required thickness floor 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 operation of the 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 collaboration panel radiators, heated floors and duct convectors are ensured by the installation of additional automation components.

Duct convector maintenance

Convection is based on movement 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.

Trench convectors are used where traditional ways heating is ineffective. An example would be rooms with a large glass area: French windows, balconies, loggias. In such cases, it is possible to place batteries in unconventional places - on the side walls of rooms, but the quality of heating will leave much to be desired. In addition, installing the radiator on the wall, rather than under the window (its usual place), limits the space for placing interior items.

The situation can be corrected by a heated floor, but its use is quite expensive and undesirable when it comes to wooden coverings. In conditions where it is impossible or difficult to use other options, convectors installed in the inner part of the floor and covered with a decorative grille are the best solution.

Device

In-floor heating convectors have this name based on the principle of convection used in their operation. When cold air is directed to the convector heat exchanger, its temperature increases and its density decreases. Thanks to this effect, the air is directed upward - through the decorative grille into the room. The place of the air leaving the working channel is taken by colder air, and the process is repeated.

The convector body is made from of stainless steel or galvanized. Such materials provide excellent resistance to rusting of equipment. A heat exchanger made of copper tube, bent in the shape of a horseshoe. Aluminum fins are used to increase the surface area of the exchanger. Decorative grilles can be made from different types material, including aluminum, steel or wood.

The performance level of the device depends on the temperature of the coolant, as well as on the power of the air flow. The temperature range at which the convector operates can vary from 45 to 90 degrees.

To increase the heat transfer performance, a tangential fan is built into the convector, thanks to which a powerful air flow is achieved.

Advantages and disadvantages

The main advantage of in-floor systems is the ability to integrate them into the floor in such a way that the equipment does not create any inconvenience for the residents of the house. The convector is invisible from the outside, but its work is noticeable and useful for all residents.

The only visible element of the device is the decorative grille or panel. Both devices can be made in different styles, so you can select them based on design solution for the entire room. However, it is worth noting: required condition for the materials used in the manufacture of the grille or panel - high strength, since these elements experience significant loads during operation. Best material for the manufacture of this decorative part - steel.

Note! In the manufacture of a convector, many materials are used, not only steel. In particular, metals such as aluminum and copper are used. For example, KZTO in-floor convectors are equipped with a copper-aluminum heat exchanger.

Other advantages of convectors:

Convectors are not without their disadvantages:

Equipment power

The choice of power for an underfloor heating device is carried out based on the principles used when choosing a conventional radiator. The number of required convectors and their dimensions are calculated taking into account the needs for thermal energy. In this case, potential heat losses are taken into account.

In-floor radiators can operate in heating systems with standard characteristics that are used in panel radiators (pressure indicator - up to 1 MPa, temperature level - up to 90 degrees above zero).

Power adjustment

The convector is controlled using shut-off and control valves. Apply Ball Valves, cone valves, thermostats with remote sensors, as well as thermostats with servo drives.

Using the device has both pros and cons.

Advantages:

high reliability and simplicity of design;
small sizes;
maintaining the cross section of the valves;
ease of use.

Flaws:

Inability to use an intermediate position, because The valve is operated only in the “open” or closed position.”
Possibility of water hammer when the tap is opened abruptly.

Cone valves

Advantages:

smooth connection;
possibility of precise regulation of heat transfer.

Flaws:

manual control - no the best choice in terms of comfort;
low throughput.

Thermostat with remote sensor

The remote thermostat is equipped with a capillary tube, the length of which can vary between 2 and 5 meters. The tube is placed in a protected channel to avoid damage. Thanks to the use of a thermostat with a remote sensor, the service life of the convector is significantly extended and the costs of its operation are reduced. The device is controlled automatically.

Thermostat with servo drive

The servo-driven device operates with virtually no noise. The thermostat is compact and has the ability to automatically maintain a uniform temperature in the room. The device is connected to one of the convector modules. Internal thermostats (connected inside convectors) and external ones are produced.

Installation location

A niche in the floor is used to place the convector. It is recommended to think about the placement of equipment at the stage of creating a heating scheme - in this case, the cost of the work will be significantly lower. In addition, a pre-designed niche will remove a number of questions regarding the safety of structures. However, you can also create a niche in an existing building. In this case, you will have to take care to maintain the integrity of the base and the adjacent waterproofing layer.

Note! When installing equipment, it is necessary to correctly position the supply and return pipes, as well as create a weir and the possibility of pumping in case of air penetration into the system.

When installing equipment in interfloor covering it is necessary to provide for its reduction. The finishing option is selected taking into account the direction of the load-bearing beams and the type of floor. If the convector is installed along the beams, installation is greatly simplified.

Note! The performance level of the convector is directly dependent on the depth at which it is installed. Therefore, if equipment is installed in a ceiling, care must be taken to strengthen its strength.

Combination with heated floors

In some cases (high heat losses), the combined use of underfloor heating systems and in-floor channel convectors is justified. To provide stable work panel batteries, floor radiators, convectors and heated floors, used automatic system management.

Equipment service

The operation of a convection device is based on the movement of air flow, as a result of which a lot of dust and debris accumulate on and around the equipment. In addition, contamination of mechanisms is largely due to the location of the unit itself - below the floor surface level. To ensure proper operation under intensive operating conditions, in-floor heating convectors must be cleaned annually of accumulated debris and dust.

Duct convectors – great option organizations heating system in cases where there are certain restrictions. It should be noted that the installation of heating equipment of this type requires highly qualified. It is strongly not recommended to do such work with your own hands; it is better to entrust the installation to professionals.
