When erecting a building for any purpose, the arrangement of the radial distribution of the heating system is one of the most costly items of the construction estimate. For this reason, you should carefully consider each stage of creating a heating structure, paying attention to even minor details.

Among other solutions, it is necessary to decide on the method of piping so that the heat supply system turns out to be the most efficient, reliable and trouble-free in operation. According to experts in the field of heat engineering, the option of laying pipes from a source of thermal energy throughout the building is considered modern and promising, which is called radiant heating of the house.

Features of the beam heat supply scheme

The radiant heating system is the optimal choice of heating method for houses with a large number of rooms and utility rooms or for buildings with several floors. Thanks to its installation, the efficiency of the equipment and the quality of heat transfer are significantly increased, since there is no unnecessary heat loss. In the photo you can see what one of the options for the collector circuit for heating a house looks like.

The principle of operation of the beam routing is simple, but it has a number of features. It implies the location of several on each floor, from which they organize the laying of pipelines for the direct and reverse supply of the coolant (in more detail: ""). If a radial distribution of a heating system is created, the instructions for such a scheme regulate the installation of structural elements in a cement screed.

The heating piping must be laid before the start of internal repair work. If this is not done, then it will be necessary to tear off the screed, lay pipes and re-fill the floors with a special solution.

Elements of the collector heating circuit

Radiation heating of a private house is a structure consisting of several main elements:

1. Heating boiler... This device is the starting point, since from it the hot coolant is directed to pipelines and radiators. The power of the heating unit must correspond to the heat transfer of the heating equipment. There is the following nuance: radial, in contrast to other options for pipeline routing, has a greater degree of heat loss, which must certainly be taken into account when calculating equipment parameters.
2. Circulation pump... According to the peculiarity of its device, the radial heating distribution is of a closed type and for its operation requires forced circulation of the heat carrier fluid. For this purpose, a special pump is installed that creates a certain pressure and pumping liquid. As a result, the required temperature regime is provided, which guarantees the efficient operation of the heat supply system.

   When choosing a circulation pump for radiant heating, you should pay attention to a number of parameters, including the length of pipelines and materials for the manufacture of radiators.

   In addition, the pump power is not one of its most important characteristics; the speed at which the liquid will be pumped should be taken into account. This parameter shows the volume of the coolant transported by the circulation device per unit of time.

   The radiant circuit of the heating system always contains a variety of thermostatic or shut-off and control elements. They provide the necessary consumption of the carrier of thermal energy in each branch of the structure. The installation of thermometers and air extractors operating in automatic mode will help create additional conditions for more efficient operation of the heating structure without unnecessary costs.

   Collectors on the domestic market are offered to consumers in a wide range. The choice of a specific device is based on the number of projected heating circuits or connected radiators. Combs are made from various materials - it can be brass or steel, as well as polymer products.

3. Cabinets... The radiant heating circuit requires that all the elements included in it be located in special structures equipped for them. , shut-off valves, pipelines must be placed in manifold cabinets with a simple design. They are both built-in walls in a niche and external ones, but at the same time they differ in functionality and practicality.

Selection of pipes for radial distribution of the heating system

Before proceeding with the arrangement of such a structure as a radial distribution of a heating system, it is necessary to determine which supply and exhaust pipes should be purchased. Their parameters are very important.

So, the following elements of the system must have the same dimensions of pipes:

• heating boiler;
• supply line;
• collector entrance.

Based on this, it is necessary to select the diameters of the same pipes, in the event that it turns out that they are different, special adapters will be required.

The materials from which pipes for the supply and removal of hot and already cooled coolant are made are very different. But experts recommend giving preference to plastic products, which are affordable for many real estate owners and ease of installation work. But even when choosing such pipes, it is necessary to take into account the resistance to the negative effects of aggressive media and high temperatures.

Collector system and underfloor heating

But such a heating option has design features, which must be taken into account at the stage of designing the heat supply of a building:

• on all circuits, the collectors must be supplied with thermostatic valves and devices that regulate the flow rate of the coolant;
• when implementing a pipe routing scheme for a floor heating system, thermostatic heads and electric thermal drives are used. Thanks to these devices, the underfloor heating structure immediately reacts to changes in the air temperature in the room, maintaining comfort and coziness in it;
• when choosing the type of distribution system, you need to know that it can be made according to a standard or individual scheme. Professionals advise giving preference to the second option. In individual systems, then not only the boiler operates in a normal mode, but there are no significant temperature differences, and the fuel is consumed in an economical mode. Underfloor heating made using an individual beam wiring scheme can be installed in any building.

Collector system advantages

The radiant heating system has a number of advantages over one- and two-pipe designs.

Among them, the main ones are:

• the ability to hide the laying of the pipeline and other equipment;
• lack of connections and as a result of weak points between the collector and heating radiators;
• simple installation of the system and the performance of work independently, even without special skills. The number of connections is minimal and therefore the assembly is carried out in the shortest possible time;
• stable functioning of the heating structure. In the case of using the beam wiring method, there is no likelihood of water hammer. This problem is especially relevant in the case when the installation of imported sanitary ware is to be carried out, for which the boundary pressure is 3 atmospheres;
• in order to repair or replace damaged sections of the pipeline, it is enough to turn off the beam of the circuit, and the entire system will continue to function in the same mode;
• the equipment has an affordable cost, like all its components;
• simplification of the design and installation process of the heating structure due to the use of pipes of the same diameter coming from the comb.

The radiant heating system is characterized by efficiency, performance, inexpensive price, safety and comfort. You can use this scheme in any building for its intended purpose, from your own home to a large office building.

Video about the radial distribution of the heating system:

One of the main elements of the collector heating system is the collector (comb, collector block), which distributes the coolant coming from the boiler over several circuits. The number of circuits corresponds to the number of taps on the collector, how many taps are on the collector, there are so many radiators in the house.

The collector allows you to evenly distribute the coolant to each heating device, due to which all radiators are heated to the same temperature. Uniform heating is ensured by the fact that each radiator has its own supply and return lines.

The design of the collector consists of several branches and one inlet / outlet through which the heat carrier enters / returns from / to the heat source. Often a distribution manifold, automatic air vent, flow meters and thermostats.

Manifold Cabinet Applications

When installing a radial heating system in a private house, it is recommended to place the collector itself, the circulation pump, shut-off and control valves in the manifold cabinet, which hides the equipment and numerous pipes and makes the room more aesthetic. In addition, it allows you to protect equipment from external mechanical stress. The pipes are led out through the lower, open part of the cabinet. The manifold cabinet is installed in the same place as the separate manifold, i.e. mounted on the wall, if possible, in the center of the house.

Control cabinet with comb, Wilo circulation pump, thermostats and electrical ...

Note! Often, when installing a collector heating system, it is not a factory collector that is used, but a self-made one, made by hand. As a rule, polypropylene tees are used for its manufacture, which are connected to each other using short sections of a suitable diameter. The result is a collector that performs exactly the same role as the factory one. The only disadvantage of a home-made collector, which is not critical for radiator heating, is additional hydraulic resistance, which is formed due to an uneven inner surface (unequal inner section of the tee and pipe sections).

For the above reason, homemade collectors are not recommended when installing the external circuit of a ground source heat pump, because For geothermal systems, the most important point is the hydraulic characteristics of the system, the slightest decrease in which can lead to a decrease in the power of the heat pump.

In a collector-beam heating system, the most common material for the pipeline laid from the distribution manifold to heating devices is 16 mm metal-plastic. are flexible and easy to lay under the floor.

If, after pressure testing the system, the reinforced-plastic pipes are poured with a concrete screed, they must be wrapped in thermal insulation, right down to the collector itself. This will avoid damaging them during thermal expansion. expanding pipes will "rub" against the insulation, and not against the edge of the screed.

Important! The pipeline should not be laid through doorways, otherwise, during the installation of the threshold of the interior door, the pipe may be accidentally damaged when drilling. If the pipeline is laid through a load-bearing wall in a new house (which will shrink in the future), then the hole in the wall must be equipped with a sleeve that will protect the pipeline from damage.

Advantages of a collector heating system

Fast, even heating of all radiators. Each heating device has its own supply pipeline, thus, a coolant with the same temperature comes to all radiators.

Aesthetics. In most cases, the wiring of the collector-ray heating system is mounted under the floor, so only the radiators themselves and short sections of the supply and return pipelines protruding from under the floor are visible in the room.

Convenience when troubleshooting. If one of the radiators leaks, the supply or return line was accidentally damaged, or there are problems with the fittings, then to carry out repair work, it is enough to shut off the coolant supply to the problem area on the distribution manifold. At the same time, only one radiator stops working, all other elements of the system continue to function.

The ability to adjust / disable the temperature in individual rooms. If no one permanently resides in some rooms of the house, for example, guests come once a month, then during the absence of guests, a minimum temperature of 10-15 ° C can be set in such rooms so as not to freeze the system. Thus, there is no need to heat the "extra" coolant.

Flaws

High price. The prime cost of the collector heating system includes a large number of pipes (each radiator has its own supply and return), as well as the collector itself and the collector cabinet.

High heating costs during operation. Due to the large number of pipes, the volume of the coolant in a collector-beam heating system is greater than in a two-pipe system, which does not allow saving on heating. The more coolant, the more fuel will be required to heat it.

In general, a two-pipe heating system for a private house is preferable to a one-pipe one. However, the choice of options for wiring the heating system does not end there: you still need to calculate the material consumption and energy efficiency of the lower, upper and beam circuits. Each is suitable for different types of buildings and each has its own advantages and disadvantages that need to be weighed carefully.

At the stage of designing a house and drawing up an estimate for the construction of objects, a lot of issues are resolved. Thermal insulation, water supply, heating - all this is carefully calculated by each owner. A mistake at the stage of choosing materials and schemes will be costly during operation. Poor thermal insulation of premises or mistakes in the design of the heating system will lead to heat loss, freezing of water pipes, and failure of the boiler.

A two-pipe heating system for a private house is a universal option for both a one-story cottage and a city nine-story building. The circuit works due to the cyclical movement of the coolant along the circuit. The supply and return lines run in parallel to each radiator.

The installation costs and the amount of fuel that will be consumed during the heating season depend on the type of system and the heating wiring diagram in a private house.

In private houses, you can use a two-pipe heating system with bottom, top or radial distribution. Each of them is used for both natural and forced circulation. In general, gravitational two-pipe heating systems are still used in small private houses or in summer cottages, often after the abandonment of stoves. They are less effective, but acceptable for many because of their low cost.

Dead-end (A), associated (B) and collector (C) heating wiring with natural circulation of the coolant.

Top-wired two-pipe heating system: get ready to hide the pipes

When designing small cottages on one floor, a scheme is advisable in which the coolant is supplied from above to the radiators. From the boiler, the hot liquid rises up the supply riser and then descends through the pipes to the batteries. And the "return" is carried out at the bottom through all the radiators.

Upper wiring of a two-pipe system with forced (closed-type expander is installed at any point) or natural (open-type expander is installed from above) circulation.

The biggest drawback of the upper wiring is the unpresentable appearance of the supply line located under the ceiling and the cost of “masking” it. They hide the pipe in several ways:

• under false ceilings or ceiling trim;
• in ceiling niches, drywall boxes;
• in the attic. With this option, the costs of pipe insulation increase significantly;
• vertical sections are usually hidden in artificial protrusions that imitate columns.

If the circulation of the liquid occurs due to gravity, you will have to insulate the pipes in the attic in any case: an expansion tank must be located at the highest point of the system. It is needed to compensate for the increase in the volume of the hot coolant.

• limitation of the minimum pipe diameter associated with a high rate of resistance to natural circulation;
• most modern radiators are not suitable due to their small cross-section;
• the slopes of the pipes must be strictly adhered to, otherwise the heating will not work correctly.

Two-pipe heating system with bottom piping: flexibility against unstable pressure

This installation option for a two-pipe forced circulation heating system is excellent for private two-story and higher houses. Each battery is immediately connected to the "return" and supply circuits. Has many advantages:

• reduction of heat loss due to the location of pipes in heated rooms;
• the ability to start immediately after installation. This allows the remaining construction and finishing work to be carried out in a heated room;
• the possibility of floor shutdown. If necessary, you can turn off any floor and carry out repairs there, while maintaining a comfortable temperature in the premises. This guarantees stable operation of the system without the risk of freezing in cold weather;
• individual temperature conditions in all rooms. For each room, its own parameters are set, due to which high efficiency is achieved, with minimal fuel consumption;
• compactness. With the lower wiring of a two-pipe heating system in a private house, all pipes are supplied from one side, and they are easy enough to hide.

A two-pipe heating system of a private house with a lower wiring looks more aesthetically pleasing than the upper one. It gives you more room to adjust temperatures, and repairs and maintenance can be done floor by floor without leaving the entire home unheated.

But such a system is not without its drawbacks:

• high consumption of pipes, fittings and other components, especially in comparison with one-pipe wiring;
• mandatory presence of air vents. Air in pipes and batteries can lead to a complete blockage of the movement of the coolant - at any temperature in the boiler, the pipes will be cold;
• decrease in operating pressure in the supply pipe.

1 - air vent preventing the formation of air jams; 2 - thermal head designed for mechanical temperature control; 3 - shut-off valves; 4 - heating temperature sensor.

A two-pipe heating system of a private house with a lower wiring in combination with the natural movement of the coolant is practically not found.

Diagram of a two-pipe heating system with bottom wiring. Shown here are two possible circulating rings and battery connections.

The reason is that in this case the meaning of its use is practically lost, the pipes still run from ceiling to floor in every room. To the disadvantages of such a system is added the mandatory presence of an open-type expansion tank, which will have to be installed in the attic and, therefore, insulate this room.

Two-pipe radiant heating system: significant fuel savings in the first five years

The old beam wiring scheme, which in Soviet times was widely used in the construction of multi-storey buildings, assumed the diversion of pipes from a common riser to each radiator. But, if one of the tenants of one floor decided to change the temperature in the room, it was felt well in almost the entire house. Strictly speaking, it could also be balanced, but it is extremely difficult to do this. Now the scheme has been revised, instead of a common riser, a collector appeared in it (hence the second name of the wiring "collector"), and with it a lot of advantages.

A two-pipe heating system of a private house with modern radial wiring, according to all experts, is the most energy efficient. Each battery is powered directly from the boiler, thanks to the presence of a distribution manifold. It is usually located in the boiler room, and in the absence of the latter, in a special cabinet.

The mandatory presence of a circulation pump allows you to reduce the delta of liquid temperatures at the inlet and outlet of the boiler, increasing the heating efficiency.

Collector or beam wiring is an economical option for a two-pipe system in operation. Thanks to the distribution manifold, each individual radiator can be switched off and adjusted.

Disadvantages of radial (collector) wiring are heard by everyone:

• bulkiness of the collector. It must be placed either in a separate room, or you have to put it in a closet, which is also not easy to disguise in the room;
• almost mandatory presence of a pump in the system;
• more pipes are needed than with any other routing.

But few can name the advantages of collector two-pipe wiring:

• individual temperature regime for each room in manual or automatic modes;
• independent power supply and the ability to turn off the supply and "return" separately for each radiator. Repair or maintenance takes place without turning off the heating throughout the house;
• when laying in the floor, only one-piece pipe lengths are used without any connections. The probability of rupture or damage to the area passing under the floor covering is very small;
• a relatively small number of fittings and other connecting elements;
• Convenience and simplicity of calculations: pipes for supply and return lines of each radiator have the same diameter.

A radial two-pipe heating system allows you to lay pipes in the floor. This is possible due to the fact that the collector and the radiator are connected with one whole section of the pipeline, and all fittings are attached after it is brought to the surface.

At the design stage, the estimate of a two-pipe radial heating system for a private house with forced circulation looks scary in comparison with any other. But, if you calculate the fuel consumption, taking into account the individual settings of the temperature in the premises and the time of day (at least for the first three to five years), then the situation changes to the exact opposite. At the same time, during the operation period, additional savings are achieved by adjusting to weather conditions.

The variety of heating schemes for buildings existing today allows you to easily choose the optimal heat supply option. However, not all of them can be quite effective in providing heat to houses with complex configurations or multi-room layouts. And in difficult projects, a modern radiant heating system has proven itself well, not yet very popular, but gradually gaining recognition from both specialists and real estate owners.

Unlike others, such a scheme provides for individual heating of each of the installed heating devices, i.e. Both the supply and the removal of the coolant are carried out in parallel through pipes separately supplied to the radiator. Outwardly, the configuration of this system resembles rays radiating in different directions from a heat source, which gave it its name.

Radiant heating can be organized with one or two pipes. The greatest application is found in the second option, which is characterized by higher heat transfer rates, and, consequently, greater efficiency.

Figure 1 - General diagram of a radiant heating system

The structure of the radiant heating system

Any heating system has in its structure a heat source (boiler, stove, boiler), heating devices (radiators, convectors), pipes, shut-off and control valves and, in most cases, a circulation pump. The beam scheme also implies the use of the above elements, as well as the important equipment that distinguishes it from other equipment - the collector.

Many of the listed structural components are standard; therefore, it is inappropriate to dwell on their description. Below will be considered only those of them to which special requirements are imposed.

Heat sources

As you know, this is the main unit of any home heating system, the choice of which should be approached reasonably. The beam scheme is structurally rather complicated and, accordingly, requires powerful equipment.

When choosing the power of the boiler, it must be borne in mind that the branched network of pipelines laid during radiant heating, as a rule, in the floor structure, causes somewhat large heat losses that affect the efficiency of the system as a whole.

Heating manifold

The second most important element in such a heat supply system is collector... It is a device in the form of a short pipe with numerous radiator connections. In the literature, you can often find another name for it - comb.

Figure 2 - Heating collector

The dimensions of the collector can be adjusted during operation, adding new sections as new heating devices are connected.

Its main function is the centralized distribution of the heat carrier from the heat source to the heating devices. It also allows you to adjust the heating intensity of each of them, as well as turn off a separate circuit for repair or planned replacement without affecting the operation of the system by installing various types of shut-off and thermostatic valves.

Radiant heating, as a two-pipe system, involves the use of two collectors: supply and outlet, which are usually installed in pairs. And to accommodate the entire unit, it is recommended to use a special cabinet, which will not only provide free access to the equipment, but also hide its unaesthetic appearance.

It should be noted that the use of collectors in the heating circuit makes it easy to modernize and allows you to connect it to the Smart Home system. Specially installed sensors provide the ability to automatically control the degree of heating of the coolant, depending on temperature fluctuations in the premises, as well as remote control of the heating of the house.

Circulation pump

A radiant heating system, as a rule, implies forced circulation of the coolant, therefore, it necessarily requires the installation of a pump.

When choosing a model of a circulation pump, one should take into account not only its power, but also such a parameter as the rate of pumping water per unit of time.

Depending on the complexity of the configuration of the circuit, as well as the length of the pipelines, two devices may be required, mounted both on the supply and on the return.

Pipes

For the organization of the ray heating circuit, metal, metal-plastic and polypropylene pipes can be used. When choosing a specific type, one should proceed not only from the cost of products, but also the laboriousness of installation and repair. In this regard, the plastic version has found the greatest application.

When purchasing pipes, it must be borne in mind that their diameter must correspond to the dimensions of the inlets and outlets of the boiler and the collector. If necessary, the use of adapters is allowed.

The main advantages and disadvantages of a radiant heating system

The organization of the radiant heating scheme predetermined a number of its advantages, among which it should be noted:

• reliable operation - the system eliminates the likelihood of water hammer; there are few weak points in it, since the number of pipeline connections from the collector to the radiator is minimized, or they are completely absent;
• independence from the configuration and size of the building (flexibility) - it allows you to provide effective heating of a house of any layout and number of storeys;
• balance - all heating devices heat up evenly;
• the ability to regulate, including automated, the temperature in each room;
• simplicity of repair and maintenance work - replacement of damaged areas does not require opening the floor covering; to carry out such events, the required circuit (beam) is turned off without affecting the functionality of the system;
• the ability to modify the system at any stage of development and operation;
• aesthetic appearance - pipelines are usually laid in the floor structure, and the collectors are installed in special cabinets or niches.

Despite its high efficiency, the radiant heating scheme has several disadvantages:

• high material consumption and, accordingly, the price - due to the significant total length of pipelines, as well as the need to purchase a large number of connecting elements, control valves, manifolds, pumps, sensors, etc .;
• the need for competent and high-quality installation in order to avoid problems in the future.

Existing schemes and nuances of mounting the beam system

The classic version of such heat supply provides for the installation of heating collectors on each of the floors or parts (with a complex configuration) of the building.

In this case, the collectors are mounted on the walls (in existing or pre-provided niches) or placed in special cabinets, and the piping system is laid along the subfloor, as a rule, before the screed is made.

Figure 3 - Installation diagram of the radiant heating system

If the manifold is located above the radiators, air will accumulate in it over time. To exclude this, the mandatory installation of automatic air vents is required.

There is also an option in which the heating devices are located at a higher level, i.e. the comb is installed in the basement or basement. In this case, the pipelines are laid along the walls, which are subsequently sheathed with structures of various types (gypsum plasterboards, PVC panels, etc.) to give them an aesthetic appearance.

Figure 4 - Radiant heating with a bottom collector location

In two-storey houses, small in area, sometimes you can also find a scheme using one collector unit, which provides heating for both levels. In this case, it is required to purchase a sufficiently powerful pump capable of pumping the coolant to all floors. But since the cost of the corresponding equipment is quite high, this option is practically not used.

Figure 5 - Scheme of radiation heating of a two-story house with one collector unit

A radiant heating system is a principle of organizing heating with several circuits and individual connection of individual devices. In this case, the system can be controlled from one place.

Advantages and disadvantages

The advantages of the ray system include the following factors:

The radial wiring of the heating system is not devoid of certain shortcomings:

1. The system can be exclusively two-pipe, which entails additional consumption of materials.
2. Installation work is more complex than in the case of a sequential circuit.
3. Only solid pipes without joints are allowed, since the pipeline is laid under the screed. The requirement is due to the increased risk of leaks precisely at the joints.
4. It is necessary to purchase circulation pumps for each circuit.

Do-it-yourself beam system

First of all, you need to draw the ray diagram on paper. Here you cannot do without at least minimal skills of the designer and understanding of the basic principles of the functioning of the heating system. In the absence of experience in design, you can order a drawing from the design organization.

For those who decide to do all the work on their own, it is recommended to divide the work into several sequential parts:

1. Analysis of the characteristics of the room. The basic rule for laying a pipeline is the absence of a surface finish, since the pipes are laid in a screed.
2. Locating batteries. Install radiators on the walls under the windows.
3. Drawing up a floor plan. It indicates the initial data, namely: the places where the batteries and the boiler are installed.
4. The plan should also include piping locations and the location of the central manifold.
5. Indication of safety and shut-off valves. The necessary equipment includes pressure gauges, thermometers, Mayevsky taps, overlap taps, etc. The plan must list all devices and indicate the order in which they are installed. You will also need air vents - one for each circuit. Air vents have an important function - to prevent the formation of air pockets.

Collector or radial piping

The radiant heating system is based on the work of the collector. This device is used to transfer the heat carrier from the central line to the local circuits. The collector (another name is a comb) looks like a hollow pipe with a pipe for the inlet (outlet) of the coolant. Also on the manifold there are separate connecting elements for each circuit.

To operate the beam system, two types of collectors are required:

1. Input. The kit includes a pump and a control valve (two- or three-way). The valve is equipped with a thermometer built into the manifold body. After receiving information from the thermometer, the valve automatically mixes hot water into the cold heat carrier.
2. Day off. When the coolant has passed the circle along the circuit, it must return to the boiler, where it will be reheated. An outlet collector is provided to collect the heat carrier. Additional devices can be installed on the branch pipes - balancing flow controllers, which change the water temperature and the throughput characteristics of the system.

To an inexperienced eye, it may seem that the collector is not so necessary if the distribution is organized using tees. However, in this case, it will not be possible to make the system stable: there will be periodic equipment failures.

Without the use of sediments, control and distribution valves, the risk of downtime of circuits increases in the absence of circulation of a heat carrier in them.

Choice of pipes

The radiant heating system of a two-story house has a number of features. First of all, we are talking about the place where the collectors are installed. It is recommended to place a common distribution center immediately after the heat carrier leaves the boiler. The whole complex of basic equipment is usually installed in a specially designated room - the boiler room.

In large buildings, it is customary to install several distribution manifolds at once. The equipment is locked in special boxes. Moreover, if necessary, there is free access to it. Installation of collectors in a screed or under non-removable decorative panels is prohibited.

In order for the operation of the beam scheme to be controlled and uninterrupted, shut-off, protective and control valves are used:

1. Thermometers and manometers. Such devices should be located at the outlet of the heated heat carrier from the boiler. In addition, it is desirable to have such devices in each manifold. Measuring devices allow visual control over the temperature level of water in the radiant heating distribution.
2. Protective fittings. We are talking, first of all, about the Mayevsky valve and safety valves, the task of which is to stabilize the pressure indicators in the system.
3. Shut-off valves. Devices of this group help with repair and maintenance, since if they are available, work can be carried out without shutting down the system. It is only necessary to reduce the inflow of the heat carrier in one of the circuits. Stop valves are installed in front of the boiler inlet pipe, as well as on all collectors. The use of a beam system in a private house is considered the best way to organize a heating system. At the same time, an amendment must be made: the use of such a system is fully justified only if the standard heating scheme is ineffective. Therefore, at the planning stage, it is recommended to make calculations to select the best option.
