The distribution of heating pipes is carried out taking into account many features. For example, it can be done in one or two tubes. Each of these methods has its own advantages and disadvantages. Therefore, the system must be selected on an individual basis. It must take into account the structural features of the building. The distribution of heating in a private house is carried out according to certain requirements, which should be considered in more detail.

One-pipe method

When creating a one-pipe heating distribution, all its components are connected to each other. They are connected in series into one network. The result is one long pipe.

Usually one-pipe systems are filled with water. The end point where the liquid enters is the radiators. Subsequently, the heat from the heated water is transferred to the premises through the batteries.

The water in the boiler is heated. Then it moves through the pipes to enter the radiator. This heating system has several disadvantages. The main disadvantage is that the final radiator is located at a great distance from the boiler, due to which the water in it heats up weakly. You can eliminate this disadvantage with a slight modification of the battery. It should be done with multiple sections. If you follow these tips, a one-pipe system becomes much more efficient.

This wiring diagram for heating a private house works great if you install it in a building with two floors. The explanation is quite simple. If such a wiring was mounted in one-story building, one would have to look for a suitable place for the collector. Such an element is needed for the proper operation of the entire system.

The boost manifold is required to accelerate heat transfer to the radiators. The device allows you to maintain the water temperature at the desired level and reduces the noise level.

At the same time, the efficiency of work is in direct proportion to the location of the collector. The higher it is, the better. In the presence of a house with two floors, such problems do not arise - the collector will cope with the task of maintaining heat and at the same time not creating unnecessary noise.

Other advantages of one-pipe routing:

• When choosing one-pipe wiring, you do not have to spend a lot of money. Low cost is ensured by the small number of pipes.
• Another advantage of this method of heating distribution is the possibility of laying even in the most inaccessible places.
• Simple installation and aesthetics can also be counted among the advantages of installing such a system.

However, this wiring method also has its drawbacks. For example, if you need to replace broken elements, the heating in the house will have to be completely turned off. In addition, heating is uneven. It depends on the distance between the boiler and the remote battery.

However, in the case of modernization of the structure and with proper installation, it will be quite effective. You can install such a system in several steps. The work can be done independently.

Types of one-pipe wiring

One-pipe heating wiring may differ in design. Different systems differ in certain features:

Schemes of such varieties of one-pipe systems should be studied before determining the type of heating wiring.

Features of one-pipe wiring

It is quite easy to install all the details of the system inside the house. In this case, it starts from the water supply point and ends at the heating equipment. The diagonal connection is the most efficient and is therefore the preferred choice. An expansion tank must be placed in the building.

There is also a simpler option that is easy to implement on your own. In this case, it is necessary to put the door on the flight of stairs. This will isolate the floors from each other. This option is quite effective, although not very aesthetic.

Advice! Before wiring, you need to study the various diagrams. Then it will be much easier to decide on the choice of the system.

Two-pipe wiring

Such systems can be as efficient as single-pipe systems. This method is suitable for heating houses with one and two floors. Its difference is that the temperature can be independently changed in any room.

Another feature of the two-pipe system is the fact that the direct and return circuits are separate from each other.

The heated liquid is fed into the system through the supply channels. Through the inlet pipes, water begins to flow to the batteries. It can also be carried out to warm floors. After the liquid has cooled, it is automatically withdrawn back. Such systems have one positive feature - how the water will flow to certain batteries can be manually adjusted.

Top routing can be invisible if pipes are mounted above doorways and closed decorative elements... In this case, the pipes will be masked as much as possible.

If the system is installed in a building with two floors, an open tank can be installed. However, it can only be placed in the attic. With the lower routing, the pipes will be located below the windowsill.

This method is a little more complicated in terms of implementation, since, in addition to installing pipes, you will have to install an open expansion tank. It must be installed above the placement of straight pipes.

Vertical layout with top wiring

When choosing such a model, the coolant will go to the attic from the heater. The liquid then flows to all batteries in the house.

Attention! You can prevent the system from becoming airy by removing air from time to time. For this purpose it is necessary to install an expansion tank.

Such schemes are more effective with lower wiring. This is due to the high pressure that is supplied through the risers.

Bottom wiring, vertical type

A two-pipe heating system with a bottom wiring is created in sequence:

• A main pipeline must be laid along the basement or first floor floor. It will originate from the boiler.
• It is necessary to lay vertical pipes along the main pipe, due to which the movement of the coolant to the batteries will be ensured.

When a two-pipe heating system with a bottom wiring is being designed, it is necessary to decide how the air will be removed from the pipeline. This requirement can be met by installing an air pipe and an expansion tank.

Horizontal system

The horizontal version of the wiring is quite popular, in which the coolant circulates forcibly. There are several schemes:

When installing a beam system, you will have to spend money on pipes.

Beam layout

For two-story buildings, as well as houses with many floors, if it is not possible to lay pipes along the walls, it is better to use radial heating.

If radial wiring of the heating system is carried out, the coolant is evenly distributed across all batteries. It does not matter how close the boiler is to the room. All rooms are heated equally well. You can repair the system without shutting it down.

For these reasons, many users choose precisely the radial distribution of the heating system. It is especially often installed in houses with two floors. Such systems have another drawback - they are always double-pipe. Therefore, their installation is quite expensive and requires more material.

Such a wiring is a collector wiring, since the main element in it is the collector. Thanks to this element, the coolant is distributed throughout the circuits, starting from the main line.

As you can see, the heating wiring in the house is carried out different ways... When choosing the most suitable system, you should understand the scheme that is most suitable for a particular home.

Pipes for distribution

The pipe material has essential when installing the heating system. Quite often, products from metal-plastic, polypropylene, copper are chosen. Galvanized pipes and stainless steel models are often used.

Each type of pipe deserves a separate consideration:

Such features of the choice of pipes from various materials must be taken into account.

As you can see, there are many features of creating a wiring in a private house. This is due to differences in the area of ​​buildings and their number of storeys. When choosing a specific scheme, it is important to consider such parameters. The installation of the heating system must follow a predefined wiring plan. When designing a circuit, it is better to enlist the support of professionals. This will help make the heating system as efficient as possible.

In words, composing and discussing a heating system is a simple matter. However, in order for it to function correctly, be efficient and economical, each element and node should be planned and calculated in detail. The distribution of heating from a boiler in a private house is laid not only taking into account beauty and comfort. It is important to consider the type of system, the characteristics of the materials to be used, and adhere to the general requirements.

Primary requirements

The main task is to connect the boiler and all radiators in the most effective way... At the same time, it is important to take into account a number of requirements:

• The routing should be laid along the route with the shortest length.
• The hydraulic resistance of pipes, valves and fittings should be reduced as much as possible.
• It is necessary to think over and arrange all functional units on the line with a minimum number of elbows, tees and valves. This refers to a safety group, an expansion tank, a circulation pump, a connection for draining and filling the system, etc.
• Pipes are selected based on the performance characteristics of the material and the heating system.
• Pipe diameters are designed to minimize head loss on one side and reduce pipe volume on the other.

Pipe diameter

Theoretically, it is quite difficult to calculate the optimal pipe diameter for a heating system in a house. The required head, static and dynamic pressure, resistance of the pipeline are taken into account, taking into account the route of laying, the roughness of the inner surface of the pipes and many additional parameters. In practice, you still have to choose from a fairly limited list of pipe diameters from a particular material. The sizes and basic characteristics of pipes have long been standardized, as are all the additional elements necessary for assembling the heating circuit from the boiler to the radiators.

The main idea is to ensure:

• the speed of movement of the coolant in the pipes at the level of 0.4-0.6 m / s;
• the resistance of the entire heating circuit is lower than the head created by a pump or gravity in a system with natural circulation;
• the minimum volume of the coolant in the pipes. Not to be confused with the total volume, including the boiler and, if necessary, the storage tank.

We reduce the resistance of pipes and circuits

For any wiring scheme or method of circulation of the coolant, the resistance of the pipeline should be reduced and the optimal movement of the fluid through the pipes should be ensured, avoiding both laminar movement and completely turbulent.

For systems with natural circulation:

• Any turns and elbows along the route are performed taking into account the minimum allowable turning radius for the type of pipe used.
• Transitions between pipes with different diameters, insertion of risers into the distributor manifold are performed without narrowing a smaller diameter and, if possible, with a gradual expansion / narrowing of the channel.
• In front of shut-off, control valves, radiators or other equipment, a flat pipe section of at least 5-6 pipe diameters should be formed in order to exclude unnecessary turbulence and vortices in the fluid flow.

For a system with forced circulation, the previous tips are not necessary, it is important that the resistance of the circuit is less than the head created by the pump. However, if all the requirements are met, the load on the pump will decrease and, accordingly, its working resource will increase. Due to the forced pumping of the coolant, it is possible to use metal-plastic pipes with a small cross-section, a lower two-pipe or one-pipe connection scheme, including packing pipes in a screed or walls.

Wiring diagrams

In practice, a large number of possible connection types are used. You can select four main ones, and on their basis you can already pick up either ready-made solution, or combined.

1. One-pipe wiring with or without booster manifold. From the boiler, the pipe goes to the first radiator. Radiators are connected in series, and from the last in the heat exchanger circuit there is a return pipe to the cold inlet of the boiler. By routing orientation method:

For any method of switching on, a set of regulating equipment of the safety and diagnostic group must be selected. The composition of the equipment differs depending on the presence of a pump or the use of a gravity system.

For natural circulation, everything is extremely simple:

1. A line is needed from the boiler to the expansion tank, located as high as possible.
2. A pipe for connecting radiators is diverted from the expansion tank or from the collector directly next to the tank. In the case of the booster manifold and the lower one-pipe wiring, the pipe is lowered with a gradual slope towards the first radiator.
3. Further, the wiring is carried out on the radiators according to the selected connection method, with a mandatory slope of at least 2-3 degrees.
4. A return line runs from the last radiator to the boiler and is connected to the lower cold lead. On the return line, a tee with a shut-off valve and a union for draining the coolant is cut in directly near the boiler.

It is more important to correctly route the pipes. Connection points and fittings should not constrict the duct cross-section. The pipe turn or elbow is selected with a turning radius of at least 1.5 pipe diameters. If the pipe goes down to the radiator from above or rises, then an elbow is first formed, and then the bypass and radiator are cut in.

For forced circulation, the composition of the equipment has been significantly expanded:

• Expansion tank, membrane type. Installation on the hot and cold outlet of the boiler is allowed, the main thing is as close as possible to the heat exchanger or heat accumulator. For solid fuel (TT) boilers, due to the impossibility of accurately regulating the outlet water temperature, a direct outlet with a length of at least a meter is first mounted steel pipe, and after connecting the equipment. The expansion tank for TT boilers is installed on the cold return line.
• Security group(air vent, safety valve, pressure gauge). The safety group is located at the hot outlet of the boiler. There must be a short pipe section from the boiler safety group with the maximum permissible diameter and without any shut-off valves capable of narrowing the channel (ball valves are allowed). The safety group is installed at the top point of the contour.
• Coarse filter... An obligatory element, even taking into account the preparation of the coolant. Installed in front of the circulation pump on the return line.
• Circulation pump... By default, it is set on the return line, where the temperature of the heating medium is lower. If the wiring of the system is at least theoretically suitable for natural circulation, then the pump is connected in parallel with a common pipe with a bypass. Shut-off valves are installed on both sides of the pump and on the bypass. In other cases, it is allowed to install the pump in direct flow into the return flow gap with shut-off valves on both sides.
• Additional pressure gauges for diagnostics. To diagnose and check the efficiency of heating, it is important to know the pressure at both boiler outlets, on both sides of the circulation pump and the coarse filter, in addition to the pressure gauge installed with the safety group. Depending on the sequence of connecting the equipment, the points may overlap and ultimately it will be necessary to install 2-3 pressure gauges using three-way valves or tees.
• Three-way valve for bypass to the boiler.
• Tee branch with shut-off valves for filling the system with coolant and draining.

Before choosing the entire list of equipment, you should find out what is already in the heating boiler itself, often in wall-mounted gas or electric boilers there is an expansion tank and a safety group at least.

Without regard to the wiring method and the variant of the coolant circulation, it is advisable to provide a bypass for each radiator. This will avoid stopping the movement of liquid due to air congestion and will make it possible to regulate the thermal power of each radiator separately when installing a three-way valve with a thermostat.

All equipment should be arranged as close to the boiler as possible, with access for inspection and maintenance. An exception is the collector wiring, in which part of the equipment remains near the boiler (general circulation pump, expansion tank, safety group), and part - at the point of installation of the collector (shut-off and control valves, additional pumps for circuits, air vents, etc.)

Price for 1m2 of works

It is difficult to independently take into account all the nuances and correctly carry out the wiring of the heating network around the house. It is much better to entrust this work to specialists who will offer the best option and a set of additional equipment. Based on experience, designers and installers are able to correctly place accents depending on the wishes of the customer: to make heating with maximum efficiency and comfort in operation, or to strive to save money on work and installation.

The cost of work includes separately installing the boiler, connecting additional equipment, piping and installing radiators. Each item has its own price list, according to which the cost of all work on equipping the heating system in the house is calculated.

The routing of pipes from the boiler to the radiators can average 300-500 rubles per linear meter, taking into account the laying, connection, passage and groove of the walls. Prices are indicative for Moscow and the region.

The choice of optimal schemes for the hot water supply and heating systems is the main task in ensuring a comfortable microclimate. The most commonly used circuits of heating systems in private houses of the following types: a system with forced and natural circulation, one-pipe, two-pipe, as well as "Leningrad" and beam piping schemes.

The heating system of houses, offices and enterprises for various purposes is key in terms of the importance of engineering communications. Despite the actively developing technologies, humanity has not yet got rid of the need to install heat sources in their homes. The heating system is operated only 4-6 months a year, while the cost of installation and components remains at a high level. The service life, reliability and efficiency in private homes largely depend on how the wiring is done.

Beginning of work

The wiring of the heating system in an apartment or a private house begins with an analysis of the conditions in which it is planned to operate it. To ensure effective heating, it is necessary to choose the right boiler, the diameter of the main pipelines, and also decide on the type of fuel.

Main components

The key components of the heating system that affect the wiring diagram are:

• Type of fuel.
• Type of boiler equipment, its main indicators and power.
• Type of heating devices.
• Features of the premises (number of storeys, insulation, area, other features).

Type of fuel

The most demanded heat source is a gas boiler. Choose this equipment for private houses, apartments or outbuildings due to economy, autonomous operation and versatility. Also, a double-circuit boiler is capable of heating water for sanitary needs. In this case, the connection of the gas boiler to the heating system, the piping layout should take into account the power of the circulation pump and the relatively low performance.

If you plan to heat a two-story building, in addition to the pump installed in a double-circuit boiler, you will need

Boilers

These devices differ in terms of installation method, type of fuel and power. Domestic boilers can operate on fuels such as solid (wood), diesel, liquid (fuel oil), coal, liquefied or natural gas, as well as pellets. Quite popular which can be electrode and heating. In addition, there are combined units that operate on different types fuel.

Many boilers are characterized by a floor-standing design, however, there are wall-mounted versions, the power of which is less than 25 kW. For the placement of electric electrode boilers, a separate place is not required, they are mounted directly into the piping system. Most modern models are equipped with a heating circuit for hot water supply; they can also be assembled in a cascade for heating large areas.

In any case, for a diagram of heating systems one-storey house you should choose boiler units that allow them to automate their work as much as possible and simplify operation. The dependence of the heating system on electrical networks is also important. This condition is fully met by the use of gas boilers, as well as the installation diagrams of the heating system in a private house without electric pumps.

Heating devices

Heating devices for private houses can be divided into two main groups - radiators and registers. Their principle of operation is quite simple. In both cases, the coolant, moving inside the heater, gradually gives off heat environment... The choice of these structures depends on the number of storeys of the building. If the premises are located on two or more levels, then it is advisable to give preference to compact and aesthetic radiators.

The use of radiators in the heating system of a private house is even more convenient from the point of view of the arrangement of furniture in the premises. They are placed under window openings, pipelines for their connection can be laid along the walls or hidden in the floor structure. Heat transfer is regulated by the number of sections, determined by the purpose and the area of ​​the heated room.

The type of heater is determined by the characteristics of the system, such as pressure, flow rate and temperature of the heating medium. Depending on these indicators, aluminum finned or cast iron radiators are selected. Aluminum structures give off heat due to incoming convective air flows in the channels between the device's ribs, cast iron - due to infrared radiation and high heat capacity.

At a coolant temperature of 90-95 ° C and a low flow rate, it is desirable to give preference to cast iron appliances. At a temperature of 65-80 ° C and there is a circulation pump in the heating system, it is preferable to use ribbed aluminum radiators.

Also, heating systems for private houses are very often supplemented with underfloor heating. The maximum comfortable microclimate will allow you to achieve the temperature of the coolant in the pipelines, which is within 40 ° C. The device of a water-heated floor requires the mandatory installation of pumping equipment.

Pipelines

The heating devices and the boiler are interconnected by pipelines, the design of which depends on the location of the radiators, the number of storeys of the building, its perimeter and length.

The material of the pipelines should be selected based on the convenience and conditions of installation, their durability, maintainability.

In modern heating systems, bulky stainless, steel and galvanized pipes have been replaced by products from polypropylene and metal-plastic. In combination with cast iron heating devices, copper pipelines are widely used.

Installation

In the presence of a heat source, the main task will be to move the heated coolant through the heating system. The operating parameters and durability of the heating system will depend on the type of the chosen scheme. As a rule, these works are carried out at the stage overhaul or construction, as they affect the entire living space.

There are two main types of heating systems. This:

• Natural (gravitational).
• Closed loop heating system in a private house. This scheme provides for artificial circulation.

In the first case, the natural circulation of the coolant is meant due to its heating and expansion. A closed system uses a closed, pressurized heating circuit. Heat redistribution and fluid circulation are provided by pumping equipment.

Any of these options can be organized by various connection schemes. The most commonly used one-pipe, two-pipe and beam wiring. Let's consider them in more detail.

One pipe system

A one-pipe connection diagram of the heating system implies a sequential installation of devices. The coolant enters the heating devices, and then, passing through them, gives off part of its heat. Thus, the last device gets a liquid with the lowest possible temperature index. To prevent this from affecting the microclimate of the room, the number of sections in the final heater must be increased.

Today, there are technologies that optimize the operation of a one-pipe heating system. Heating regulators, ball valves, thermostatic valves or balancing valves can be installed as accessories. This will balance the heat supply. Overlapping one specific radiator will not disrupt the operation of the heating system as a whole.

The wiring diagram of the heating system in a private house can be implemented as:

• Horizontal system using a circulation pump.
• Vertical system with natural or combined circulation, as well as using circulation pumping equipment.

Horizontal single pipe system

This scheme is popularly called "Leningrad". The pipes can be built into the heating structure or laid above the floor level. Therefore, in order to reduce heat transfer, it is recommended to insulate them.

The wiring diagram of a one-pipe heating system provides for the presence of a riser that supplies the coolant to the second floor and leads to the first radiator.

Temperature control is carried out using taps. They should be installed in front of the first one on each floor.

Vertical single pipe system

Such schemes of heating systems in private houses provide for the natural circulation of the coolant. The advantage of such a wiring is independence from the power supply, since the presence of a circulation pump is not required.

A significant disadvantage is the use of large-diameter pipelines, as well as the need to locate the distribution line strictly at an angle. The main disadvantage is the fact that such a scheme for connecting a heating system in a private house does not look very aesthetically pleasing. However, this can be eliminated by means of a circulation pump.

Two-pipe system

Such schemes of heating systems in private houses require significant financial costs... Also, the volume of work performed increases and, accordingly, the cost of installation.

The main advantage is the uniform distribution of the coolant throughout the system. And most importantly, the temperature regime is very simply regulated: in accordance with the needs of those living in the house.

When installing modern communications, the manufacturers of components for which are mainly foreign companies, it is recommended to connect the gas boiler to the heating system, the scheme of which is two-pipe, as this greatly facilitates the operation of pumping equipment.

Heaters can be connected from the side, bottom and diagonally. The choice of the best option mainly depends on the size of the radiators used and the material of their manufacture.

Control valves must be installed at the inlet and outlet of the heater. Also, do not forget about the drain valve, which should be located at the lowest points of the system.

The flow rate of the pipelines depends on which connection of the boiler to the heating system is chosen - a one-pipe or two-pipe scheme. It is more expedient to equip private houses with a small area with two-pipe wiring.

Additionally, such a system is equipped with a circulation pump. The presence of thermostats in each separate room allows you to set the most optimal heating mode.

If your material resources are limited, and private house small area, then you can do with one-pipe wiring.

The area of ​​buildings in which it is allowed to use one-pipe systems should not exceed 100 m 2. In this case, you can do without pumping equipment and apply natural circulation.

Beam system

The collector or beam scheme is characterized by the fact that each heating device has its own pair of pipelines for forward and reverse current. These pipelines converge on manifolds at the heater. In such a system, the length of the pipes is much higher even in comparison with the two-pipe scheme.

For uniform distribution of the coolant over the heating devices, the beam system is balanced before operation.

Conclusion

Regardless of which heating system is chosen, the scheme will be developed with its own hands or with the involvement of specialists, it is important to remember that the design and installation of these engineering communications is considered a rather complicated undertaking. If you are not confident in your own abilities, then it is preferable to seek help from specialists.

This will avoid mistakes that may arise at any stage of the start-up and operation of the heating system. In order not to eliminate shortcomings in the future, it is better to simply not allow them and foresee everything in advance.

Work on the arrangement of the heating system in a private house can be done independently if you have primary skills in working with the tool and the tool itself, or you can order it from a specialized organization.

But, in any case, do-it-yourself heating wiring in a private house begins with the theoretical part. You will need to decide which wiring diagram of the heating system you choose, how the coolant and the boiler will circulate in it, what brand will be installed in the system to heat the coolant.

Today, a person planning such work as laying out heating pipes in a private house on their own to equip a heating system has the opportunity to choose one of the four options most often used for these purposes:

A variant of the beam method of wiring the heating system

The wiring of the heating system in a private house, made according to the indicated option, has the following feature: the supply pipe is brought out to the highest point of the house (usually to the attic), here its own beam is supplied to each pipe.

We get a kind of sun with rays of supply of hot coolant to the radiators. (Another analogy is a fountain).

Collector heating system

The heating pipe layout according to the indicated option is classified as the most efficient and productive. The basis is a collector assembled in the attic, through the pipes of which the coolant is distributed. The correct routing of heating pipes and the shut-off valves installed in the collector allow, if necessary, to cut off any of the circuits without interrupting the operation of the entire CO.

It is considered the most convenient model of CO, namely this system... The coolant is supplied to the radiators through the collector. It also contains control elements, which makes it possible to regulate the temperature in any room, as well as to replace and repair a failed unit without shutting down the entire heating system.

A significant disadvantage is considered to be a large consumption of materials when installing CO according to the above scheme, as well as the requirement for the mandatory installation of a collector cabinet.

Heating wiring diagram of a private house, assembled according to a one-pipe version

This option is quite simple to implement, it will require minimum costs for the purchase of components and assembly work... All this makes it today the most popular option for installing heating systems in private residential buildings and at other facilities.

The heating pipe layout in this version allows the coolant to move sequentially from one heater to another. Moreover, in each subsequent, the temperature will be lower than in the previous one. Very often, the coolant reaches the last radiator at a low temperature, which is clearly not enough for heating.

The distribution of heating pipes in the house according to this version practically excludes the possibility of adjusting the system, because closed batteries do not let the coolant go further. And if there is a need to repair any heating device in such COs, the entire coolant is drained.

Two-pipe home heating system

It will cost significantly more than the previous version, and will require more time for assembly and adjustment. However, it will allow you to get serious benefits in the quality of heating, system performance and its efficiency.

Do-it-yourself heating wiring in a private house according to the indicated scheme warms up the object much better. Here, in mandatory there are two pipes that are supplied to each radiator. Correct routing of heating pipes ensures the following movement of the coolant. A hot coolant enters the upper one, and the cooled one is discharged along the lower one.

The advantage of the circuit: parallel connection of all heating devices. The wiring diagram for heating a private house according to the specified version allows you to repair a failed element without turning off all the CO.

Heating plan according to the method of circulation of the coolant in the system

In all currently operating CO, the coolant circulates according to one of the options indicated below.

Natural circulation, otherwise known as gravitational

In this case, the heat carrier moves due to the use of the difference in the density of the liquid having different temperatures. Hot has a lower density, so it rises to the top of the system. The colder is heavier, so it goes down.

In order to facilitate the movement of the coolant in such systems, pipes are mounted at small angles horizontally to facilitate gravity.

The main advantages of such a system are complete autonomy and maximum ease of assembly. Cons: the need for a large number pipes of large diameters. The inability to establish in such COs modern models radiators with small cross-sections and a strict requirement for the slope of the line.

Forced circulation

In this version, the heating medium is transported by a working circulation pump. And its excess, formed when heated to high temperatures, is displaced into the expansion tank.

In most versions of the CO, the tanks are closed, which ensures its protection from evaporation. Closed tanks are used without fail in systems where any of the glycol solutions acts as a coolant.

Such systems are necessarily equipped with pressure gauges. When installing these systems, you will additional expenses: you will need to buy thermostats, a pump, a pressure gauge, a tank, etc.

The advantages of the specified CO option, which the heating wiring of a two-story private house has according to the specified option: minimum volume of coolant is required, smaller required pipe diameters, constructively realized possibilities for adjusting the heating temperature of radiators, etc.
Negative: Depends on the availability of electricity to run the pump.

Heating scheme according to the layout and layout of pipelines

When choosing this version, it is better to entrust its installation to professionals, since it is rather complicated.

The type of installation is distinguished:

• Horizontal CO. It is quite convenient in that it does not require the installation of risers for subsequent branching through the existing premises.
• Vertical CO. They do not have air locks and are easy to install.

In the direction in which the coolant moves, there are:

• Direct-flow. The coolant moves from the boiler through CO to the boiler.
• Dead end. Move away from the heat source in the opposite direction.

Heating schemes for a private house, the piping in which is made according to one of the above options, requires from the contractor high-quality preliminary calculations and carefully selected necessary equipment.

In the future, it will need to be mounted strictly according to the design scheme, otherwise, the collected CO may work poorly.

How to choose the best heating layout for a private house?

When determining the required JI option, it is necessary to take into account several initial parameters:

• The total area of ​​the room that will be heated by the specified system;
• Number of floors;
• The power of the heating boiler to be installed in the system;
• What kind of coolant circulation scheme is planned to be taken as a basis.
