Sometimes it is very difficult for an uninformed homeowner to decide on the choice of a heating system. This problem is as old as the world. The debate over which is better - a single-pipe or two-pipe heating system, has been going on for a long time and has not subsided to this day. In our article, we will try to approach the issue objectively and impartially, having considered both schemes in relation to a private house.
Pros and cons of a single pipe system
To begin with, we recall that a single-pipe circuit is one horizontal collector or vertical riser, common to several radiators connected to it by both connections. The coolant, circulating through the main pipe, partially flows into the batteries, gives off heat and returns back to the same collector. The next radiator receives a mixture of chilled and hot water with a temperature lowered by several degrees. And so on until the very last radiator.
The main difference between a single-pipe heating system and a two-pipe one, which gives it some advantage, is the lack of separation into supply and return pipelines. One highway instead of two means fewer pipes and less work on laying them (piercing walls and ceilings, fastening). In theory, the total cost should also be lower, but this is not always the case. Below we will explain why.
Thanks to the advent of modern fittings, it has become possible to regulate the heat transfer of each radiator in automatic mode. True, this requires special thermostats with an increased flow area. But even they will not save the system from its main drawback - the cooling of the coolant from battery to battery. As a result, the heat transfer of each subsequent device decreases and it is necessary to increase its power by increasing the sections. And this is a cost increase.
If the line and the connection to the device are of the same diameter, then the flow will be divided approximately equally. This should not be allowed, the coolant will cool down greatly in the very first radiator. In order for a third of the flow to get into it, the size of the common collector must be made twice as large, and along the entire perimeter. Imagine if this is a two-story house with an area of 100 m2 or more, where a DN25 or DN32 pipe is laid in a circle. This is the second price increase.
If in a one-story private house it is necessary to ensure natural circulation of water, then here a single-pipe heating system differs from a two-pipe one by the presence of a vertical accelerating collector with a height of at least 2 m, installed immediately after the boiler. An exception is pumping systems with a wall-mounted boiler suspended at the required height. This is the third price increase.
Conclusion. A single pipe system is complex. It is necessary to calculate the diameters of pipelines and the power of radiators very well, to think carefully about laying highways. Then it will work efficiently and reliably. The statement about the cheapness of "Leningrad" is very controversial, especially when it is decided to assemble a circuit from metal-plastic pipes, you will simply go broke on fittings. Metal and PPR will cost less.
Pros and cons of a two-pipe system
All more or less understanding people know the difference between a single-pipe and two-pipe heating system. It lies in the fact that in the latter, each battery is connected with one supply line to the supply line, and the second - to the return line. That is, hot and cooled coolant flows through different pipelines. What does it give? Let's put the answer in the form of a list:
- distribution of water to all radiators with the same temperature;
- accordingly, the number of sections does not need to be increased;
- it is much easier to regulate and automate the entire system;
- pipe diameters for forced circulation are at least 1 size smaller than with a single-pipe scheme.
As for the shortcomings, there is only one worthy of attention. This is the consumption of pipes and the cost of laying them. But these pipes are of smaller diameter with a relatively small number of fittings. A detailed calculation of materials for one and the other system, as well as the nuances of their work, are shown in the video:
Conclusion. The advantage of a two-pipe heating system is its simplicity. The owner of a small house, having correctly determined the power of the batteries, can randomly make the wiring with a DN20 pipe, and make the connections from DN15, and the circuit will work fine. As for the high cost, it all depends on the material used, the branching of the system, and so on. Let's take the liberty of asserting that a two-pipe scheme is better than a one-pipe one.
How to convert a one-pipe heating system into a two-pipe one?
Since the difference between a single-pipe and a two-pipe system is the separation of the two streams, it is technically quite easy to make a conversion. It is necessary to lay a second pipeline along the existing highway, whose diameter can be taken 1 size smaller. The end of the old collector must be cut off near the last device and plugged, the remaining section to the boiler must be connected to a new pipe.
You will get a scheme with the associated movement of water, only the coolant leaving the batteries must be sent to a new line. To do this, one inlet section of each radiator will have to be reconnected from the old collector to the new one, as shown in the diagram:
It must be understood that in the process of alteration, one may encounter such difficulties as lack of space for a second pipe, the inability to punch a hole in a wall or ceiling, and so on. Therefore, before starting such a reconstruction, it is necessary to think over everything well. It may be possible to establish the normal operation of the existing one-pipe system.
Conclusion
In the field of private housing construction, the advantages of a two-pipe heating system over a single-pipe one are obvious. But the latter does not give up its positions, because it has many fans. In any case, the choice is yours.

Today, there are a variety of ways to organize systems, among which heating on two wings with a pump has gained great popularity. Its device is made according to the principle of effective maintenance with minimal heat loss. The two-pipe heating system has become especially in demand in single-storey, multi-storey and private houses, the connection of which allows you to achieve all the necessary conditions for a comfortable stay.
What is a two-pipe heating system
Two-pipe heating has been used more and more often in recent years, and this despite the fact that the installation of a single-pipe version is usually much cheaper. This model provides the ability to adjust the temperature in each room of a residential building at will, because. a special control valve is provided for this. As for the one-pipe scheme, unlike the two-pipe one, its coolant, when circulating, sequentially passes absolutely all radiators.
As for the model of two pipes, here a pipe is separately supplied to each radiator, designed to inject the coolant. And the return pipeline is collected from each battery into a separate circuit, the function of which is to deliver the cooled carrier back to the flow or wall-mounted boiler. This circuit (natural / forced circulation) is called the return flow, and it has become especially popular in apartment buildings when it becomes necessary to heat all floors with a single boiler.
Advantages
Double-circuit heating, despite the higher installation cost compared to some other analogues, is suitable for objects of any configuration and number of storeys - this is a very important advantage. In addition, the coolant that enters all heating devices has an identical temperature, which makes it possible to evenly heat all rooms.
The remaining advantages of a two-pipe heating system are the possibility of installing special thermostats on radiators and the fact that a breakdown of one of the devices will in no way affect the operation of others. In addition, by installing valves on each battery, you can reduce water consumption, which is a big plus for the family budget.
Flaws
The above system has one significant disadvantage, which is that all its components and their installation are much more expensive than the organization of a single-pipe model. It turns out that not all tenants can afford it. Other disadvantages of a two-pipe heating system are the complexity of installation and the large number of pipes and special connecting elements.
Scheme of a two-pipe heating system
As mentioned above, a similar method of organizing a heating system differs from other options in a more complex architecture. The dual-circuit heating scheme is a pair of closed-type circuits. One of them is used to supply the heated coolant to the batteries, the other is to send the spent, i.e., cooled liquid back for heating. The use of this method on a particular object depends to a greater extent on the power of the boiler.
dead end
In this embodiment, the direction of supply of heated water and return is multidirectional. A two-pipe dead-end heating system involves the installation of batteries, each of which has an identical number of sections. To balance a system with such a movement of heated water, the valve installed on the first radiator must be screwed with great force in order to shut off.
Passing
This circuit is also called the Tichelman loop. An associated two-pipe heating system or just a ride is easier to balance and adjust, especially if the line is very long. With this method of organizing heating, each battery requires the installation of a needle valve or a device such as a thermostatic valve.
Horizontal
There is also such a type of scheme as a two-pipe horizontal heating system, which is widely used in one- and two-story houses. It is also used in rooms with a basement, where you can easily place the necessary communication networks and devices. When using this wiring, the installation of the supply pipeline can be done under the radiators or on the same level with them. But this scheme has a drawback, which is the frequent formation of air pockets. In order to get rid of them, the installation of Mayevsky cranes on each device is required.
vertical
A scheme of this type is more often used in houses with 2-3 or more floors. But its organization requires the presence of a large number of pipes. It should be noted that a vertical two-pipe heating system has such a significant advantage as the ability to automatically remove air that exits through a drain valve or expansion tank. If the latter is installed in the attic, then this room must be insulated. In general, with this scheme, the temperature distribution over the heating devices is carried out evenly.
Two-pipe heating system with bottom wiring
If you decide to choose this scheme, then keep in mind that it can be collector or with radiators mounted in parallel. Scheme of a two-pipe heating system with a lower wiring of the first type: two pipelines depart from the collector to each battery, which are supply and discharge. This model with the wiring of the lower type has the following advantages:
- installation of shut-off valves is carried out in one room;
- high level of efficiency;
- the possibility of installation in an unfinished object;
- overlapping and adjustment is carried out easily and simply;
- the ability to turn off the top floor if no one lives there.
With top wiring
A closed two-pipe heating system with an upper wiring is used to a greater extent due to the fact that it is devoid of air pockets and has a high water circulation rate. Before making a calculation, installing a filter, finding a photo with a detailed description of the scheme, it is necessary to correlate the costs of this option with the benefits and take into account the following disadvantages:
- unaesthetic appearance of the premises due to open communications;
- high consumption of pipes and necessary materials;
- the appearance of problems associated with the placement of the tank;
- rooms located on the second floor warm up somewhat better;
- the impossibility of location in rooms with large footage;
- additional costs associated with decorative trim, which should hide the pipes.
Connecting heating radiators with a two-pipe system
Installation work related to the installation of double-circuit heating includes several stages. Radiator connection diagram:
- At the first stage, the boiler is installed, for which a specially designated place is prepared, for example, a basement.
- Further, the installed equipment is connected to an expansion tank mounted in the attic.
- Then, a pipe is drawn from the collector to each radiator battery to move the coolant.
- At the next stage, pipes for heated water are again drawn from each radiator, which will give them their heat.
- All return pipes form a single circuit, which is further connected to the boiler.
If a circulation pump is used in such a circuit system, then it is installed directly in the return circuit. The fact is that the design of the pumps consists of various cuffs and gaskets, which are made of rubber and do not withstand high temperatures. This completes all installation work.

Obviously, it is most advantageous to install a more efficient one that will not only cope with its functions, but will also serve you for more than one year. In order not to remain "out of the blue" and not make a mistake with the choice of the heating system.
You need to properly understand which of the heating systems is best for you and why.
Thus, you will know which system is better from a technical point of view and how to choose it, taking into account your budget.
High water pressure ensures a natural cycle, and antifreeze makes the system more economical.
Disadvantages of a single pipe system - a very complex thermal and hydraulic calculation of the network, since, having made a mistake in the calculations of devices, it is very difficult to eliminate it.
Also, this is a very high hydrodynamic resistance and an involuntary number of heating devices on one line.
The flow of the coolant goes immediately to everything and is not subject to separate adjustment.
In addition, very high heat losses.
In order to be able to regulate the operation of individual devices connected to one riser, bypasses (closing sections) are connected to the network - this is a jumper in the form of a piece of pipe connected by direct and return pipes of the radiator, with taps and valves.
To be able to control the temperature of each individually, the bypass allows you to connect automatic thermostats to the radiator.
In addition, it also makes it possible, in the event of a breakdown, to replace or repair individual devices without turning off the entire heating system.
Single-pipe heating is divided into vertical and horizontal:
- vertical - this is the connection of all batteries in series from top to bottom.
- horizontal - this is a serial connection of all heating devices on all floors.
Due to the accumulation of air in batteries and pipes, so-called traffic jams occur, which is a disadvantage of both systems.
Installation of a one-pipe system
Connection is made according to the scheme, using valves for airing radiators, which block the valves and plugs.
Crimping system - after which the coolant is poured into the battery and the system adjustment is directly adjusted.
Two-pipe heating system
The advantage of a two-pipe heating system - this is the installation of automatic thermostats, which gives you the full ability to adjust the temperature in individual rooms.
This also includes the independence of the operation of the circuit devices, which is provided by a special collector system.
The difference between a two-pipe and a single-pipe system is that in the first one you can connect additional batteries after connecting the main ones, as well as the possibility of extending in vertical and horizontal directions.
Unlike a single-pipe, here you can also easily correct permissible errors.
The disadvantages of this system are minimal if you have enough material resources and have the opportunity to call the master.
Installation of a heating system with lower horizontal piping
This system allows you to locate the open tank in a convenient warm place. Also, it is possible to combine expansion and supply tanks allow you to use hot water directly from the heating system itself.
In systems with forced circulation, to reduce pipe consumption, the discharge and supply risers are located at the level of the first.

All heating systems today are divided into two main types: one-pipe and two-pipe heating systems. Each type has its own characteristics and features, but two-pipe heating systems have become the most popular. Sometimes people wonder, one-pipe or two-pipe heating system - what to choose?
Single pipe heating system
Such a heating system is a closed circuit, which is interrupted by the boiler. The installation of such a system involves the installation of a pipeline in all rooms located in the house. Radiators are connected to the pipes, and a coolant is launched into the system (its role is most often played by distilled water), which provides heat transfer to each room. The principle of operation of such a heating system is based on the difference in water temperatures at the beginning of the cycle and during the reverse movement, that is, the water that has passed through the entire circuit returns to the boiler cooled down.Most often, this design uses the natural circulation of the coolant. To do this, the heated water first rises to the maximum possible height, after which it gradually descends through the pipes, cooling in the process of movement.
- thermostatic valves;
- radiator regulators;
- balancing valves;
- Ball Valves.
Characteristic features of a single-pipe heating system
The most important advantage of a single-pipe heating system with natural circulation is the absence of the need for electricity. Instead, there is a significant drawback, which is expressed in a rather large diameter of the pipes and the need to create a constant slope of the pipeline.Advantages of single-pipe heating over two-pipe:
- Pipes can be connected to "warm floors" or heating radiators.
- Such a system can be installed in any room, regardless of the layout.
- A closed circuit allows you to heat the entire building as a single piece.
- Such a system is much cheaper, since it requires a much smaller amount of materials.
In multi-storey buildings, a vertical one-pipe heating system is most often used, while a horizontal one is better suited for compact one-story houses. In this case, all heating elements are located at the same height, which gives rise to the following problem: the water that has cooled down in one radiator comes to the next already cold one. Such a system is much cheaper, but also has significant drawbacks.
Radiators in such a system are not controlled: a horizontal heating system does not imply free adjustment of each heater. If necessary, bypasses can be built into such a system, which make it possible to let the coolant bypass a separate radiator, but such a device will make the system more expensive. Turning off the radiator leads to the fact that the room begins to be heated due to the heat coming from the pipes or riser.
In addition, for the efficient use of this system, it is recommended to use heating elements of different sizes. To equalize heat dissipation, the radiator installed first should be quite small, and the last radiator should be much larger.
Two-pipe heating system
Despite the presence of a number of modifications, a two-pipe heating system works on the same principle. The heated liquid rises through the riser, from where it enters the radiators. But if one pipeline circuit goes to the radiators, then the cooled liquid is removed using the second circuit. This is what makes sense. Water in such a system comes directly from the water supply. For the normal functioning of the system, it needs an expansion tank, which can be simple or complicated.
In a simple one, there is a container to which two pipes are connected. One of them is a riser designed to supply water, and the second pipe allows you to eliminate excess fluid (read: ""). In a complex design, four pipes are installed, two of which are responsible for the circulation of the liquid, and the other two monitor the water level in the system and the tank itself.
Two-pipe heating systems work great in conjunction with a pump. Circulation can be carried out both with a passing flow and a dead-end method. In the latter case, the heated and cooled liquid move in the opposite direction. Both circulation circuits are of the same length, so all radiators provide equal heat dissipation.
A two-pipe heating system bypasses a single-pipe heating system in a number of ways:
- Ability to precisely control the uniformity of heat supply in different rooms.
- The system is well suited for heating one-story buildings.
- Locking riser systems can be located in the basement, thus saving on the usable area of the building.
- There are practically no heat losses in this system.
Horizontal closed two-pipe circuit can be equipped with top and bottom wiring. The use of lower wiring allows you to add new heaters to the system gradually, as new floors are built (more: ""). The vertical system is well suited for houses with variable number of floors. In any case, a two-pipe heating system will cost more than a single-pipe one, but its use will provide much more comfort and convenience.
One-pipe or two-pipe heating system: advantages and disadvantages
In single-pipe systems, there are no return risers. The movement of the coolant in this case is provided by natural circulation or a pump. The cooled liquid enters the lower part of the system, and along the way it mixes with the coolant from the supply riser. The closed circuit ensures constant circulation of liquid in the system. Passing through the pipeline, the water cools, so the surface area of the heater, located further from the boiler, must be larger in order to increase heat transfer.
Single-pipe heating systems can be built according to two schemes: flow and mixed (read: ""). The flow circuit completely lacks any bypasses, therefore, if one heating element fails, the entire system has to be turned off. This option is currently practically not used, since it is extremely irrational. However, single-pipe systems have a low cost due to a minimum of materials and simple installation. When installing such systems, top wiring is required.
Installation of heating systems
One-pipe and two-pipe heating systems are installed in different ways, and the installation of a suitable system will depend on the parameters chosen, and any specialist can calculate the installation cost. If natural circulation is chosen for the installation, then it will be advisable to install the upper wiring, and if there is a pump and there are no problems with the power supply, the lower one can be used.In addition, methods for installing heating systems can be classified according to:
- type of wiring;
- the number of risers;
- pipe connection type.
The main classification of heating installation methods is still based on the chosen scheme. One-pipe and two-pipe heating systems have much in common, but the difference between them is too great to put them in the same row. The advantages of single-pipe heating lie on the surface: low cost and ease of operation. But this system also has enough disadvantages, and the most important of them is that if the area of \u200b\u200bthe house is too large (more than 100 sq.m.) or if there is a second floor, the single-pipe scheme simply will not justify itself. In such cases, it will be much more profitable to opt for a two-pipe heating system.
The latter option also makes it possible to choose the appropriate method for installing radiators:
- sequentially;
- parallel;
- diagonally;
- on the side.
The classification of installation methods can also be carried out according to the location of the risers:
- heating with horizontal wiring;
- heating with vertical wiring;
- heating without risers.
A single pipe system is cheaper and easier. The two-pipe system is more convenient and reliable. Regardless of whether a single-pipe or two-pipe heating system is installed in the house, space heating will still occur. The final choice depends on the homeowner, but still the two-pipe system has a large number of advantages, and its performance suggests that using such a scheme in your home will be more profitable and convenient.
In the video, a single-pipe and two-pipe heating system for comparison:
Owners of private houses often face the choice of which type of home heating to give preference. There are only two types of heating systems traditionally used in everyday life: one-pipe and two-pipe. Each type has both advantages and disadvantages. The difference between both systems lies in the different way of delivering the coolant to the heating devices. Which heating structure for your own home is better, one-pipe or two-pipe - choose directly to the owner of the house, taking into account their own domestic needs, the estimated heated area and the availability of finances.
In the first version, heat is distributed throughout the house through one pipe, sequentially heating each room of the house. In the second case, the complex is equipped with two pipes. One is a direct supply of coolant to. Another pipe serves to drain the cooled liquid back to the boiler for subsequent heating. A correct assessment of your own financial capabilities, an accurate calculation of the optimal parameters of the coolant in each individual case, will help not only determine the type of heating system, but also correctly.
You can understand and figure out what is best for you, a one-pipe or two-pipe heating system, only after a thorough study of the technical nuances.
Single pipe heating system. General representations
A single-pipe heating system can work both with a pump and with natural circulation of the coolant. Considering the second type, you should delve a little into the existing laws of physics. It is based on the principle of expansion of a liquid when heated. During operation, the heating boiler heats the coolant, which, due to the temperature difference and the pressure created, rises through the riser to the highest point of the system. The movement of the coolant upwards is carried out along one pipe, reaching the expansion tank. Accumulating there, hot water fills all series-connected batteries through a descending pipe.
Accordingly, the first connection points along the course of the coolant will receive maximum heat, while partially cooled liquid will already enter the radiators located further.
For large, multi-storey buildings, such a scheme is extremely inefficient, although in terms of installation and maintenance costs, a single-pipe system looks attractive. For private one-story houses, residential buildings with two floors, a similar principle of heat distribution is acceptable. Heating residential premises using a single-pipe scheme in a one-story house is quite effective. With a small heated area, the temperature in the radiators is almost the same. The use of the pump in longer systems also has a positive effect on the uniformity of heat distribution.
The quality of heating and the cost of installation in this case may depend on the type of connection. Diagonal connection of radiators gives greater heat transfer, but is used less often, due to the larger number of pipes needed to connect all heating appliances in residential premises.
The scheme with the lower connection of radiators looks more economical due to the lower consumption of materials. From an aesthetic point of view, this type of connection looks preferable.
Advantages of a single-pipe heating system and its disadvantages
For owners of small residential buildings, a single-pipe heating system looks tempting, especially if you pay attention to its following advantages:
- has stable hydrodynamics;
- convenience and ease of design and installation;
- low costs for equipment and materials.
The indirect advantages of a single-pipe system include the safety of the supply of coolant, which diverges through the pipeline through natural circulation.
The most common problems that owners of a single-pipe heating system have to face include the following aspects:
- technical difficulties in eliminating miscalculations in the work made during the design;
- close relationship of all elements;
- high hydrodynamic resistance of the system;
- technological limitations associated with the impossibility of independent adjustment of the coolant flow.
Despite the listed disadvantages of this type of heating, a well-designed heating system will avoid many difficulties even at the installation stage. In view of the listed advantages and the economic component, single-pipe schemes have become quite widespread. Both a single-pipe and another type, a two-pipe heating system, have real advantages. What can you win and what can you lose by choosing one of the types for your home?
Technology for connecting and locating a single-pipe heating system
Single-pipe systems are divided into vertical and horizontal. In most cases, vertical wiring is used for multi-storey buildings. In this case, all radiators are connected in series from top to bottom. With horizontal wiring, the batteries are connected one after the other horizontally. The main disadvantage of both options is frequent air congestion due to air accumulation in the radiators. The proposed scheme makes it possible to get an idea of some wiring options.
Connection methods in this case are selected at the discretion of the owner. Heating radiators can be connected via side connection, diagonal or bottom connection. The figure shows similar connection options.
For the owner of the house, the economic feasibility of the equipment installed in the house and the effect obtained are always an important aspect. Do not underestimate the option with a single-pipe heating system. Today, in practice, quite effective measures are being taken to improve heating schemes of this type.
For example: there is a technical solution that allows you to independently adjust the heating of individual radiators connected to the same line. For this purpose, bypasses are created in the system - a pipe segment that creates a bypass movement of the coolant from a straight pipe to the return, bypassing the circuit of a certain battery.
Valves and valves are placed on the bypasses, blocking the flow of the coolant. You can install thermostats on radiators that allow you to control the heating temperature in each radiator or throughout the system as a whole. A competent specialist will be able to calculate and install bypasses to achieve maximum efficiency. In the diagram you can see the principle of operation of bypasses.
Two-pipe heating system. Operating principle
Having become acquainted with the first type of heating system, a single-pipe, it's time to deal with the features and principle of operation of a two-pipe heating scheme. A thorough analysis of the technological and technical parameters of heating of this type allows consumers to make an independent choice - which heating is more efficient in a particular case, one-pipe or two-pipe.
The basic principle is the presence of two circuits along which the coolant diverges through the system. One pipe provides the coolant supply to the heating radiators. The second branch is designed so that the already cooled coolant, after passing through the radiator, returns back to the boiler. And so constantly, in a circle, while the heating is on. At first glance, the very presence of two pipelines in the scheme can repel consumers. The long length of highways, the complexity of wiring are factors that often scare owners of private houses away from a two-pipe heating system.
This is at first glance. Like single-pipe systems, two-pipe systems are divided into closed and open. The difference in this case lies in the design of the expansion tank.
Closed with a membrane expansion tank are the most practical, convenient and safe to use. The obvious benefits are confirmed by:
- even at the design stage, it is possible to equip heating devices with thermostats;
- parallel, independent connection of radiators;
- the technical possibility of adding heating devices after the installation is completed;
- ease of use of hidden gaskets;
- the ability to turn off individual radiators or branches;
- ease of adjustment of the system.
Based on the foregoing, one unambiguous conclusion can be drawn. A two-pipe heating system is much more flexible and more technologically advanced than a single-pipe one.
For comparison, the following diagram is presented:
The two-pipe System is very convenient for operation in a house in which it is planned to increase the living space, extension options are possible, both up and along the perimeter of the building. Already at the stage of work, technical errors made during the design can be easily eliminated. Such a scheme is more stable and reliable than a single-pipe one.
With all the obvious advantages, before choosing this type of heating, it is appropriate to recall the disadvantages of a two-pipe system.
It's important to know! The system is characterized by a higher complexity and cost of installation and rather cumbersome connection options.
If you have a competent specialist at hand, the necessary technical calculations have been carried out, then the listed disadvantages are easily compensated by the advantages of a two-pipe heating scheme.
As in the case of a single-pipe system, the two-pipe option involves the use of a vertical or horizontal arrangement of pipelines. Vertical system - radiators are connected to a vertical riser. This type is convenient for two-story private houses and cottages. Air congestion is not terrible for you. In the case of the horizontal version, the radiators in each room or room are connected to a pipeline located horizontally. Two-pipe horizontal heating schemes are mainly designed for heating one-story buildings and large residential buildings with the need for floor-by-floor adjustment. Arising air jams are easily eliminated by installing Mayevsky cranes on radiators.
The figure shows a vertical two-pipe heating system. Below you can see what a two-pipe horizontal type system looks like.
Traditionally, radiators can be connected using bottom and top wiring. Depending on the technical conditions and the project, the choice of wiring option depends on the owner of the house. The top wiring is more convenient. All highways can be hidden in the attic space. The system creates the circulation necessary for a good distribution of the coolant. The main disadvantage of a two-pipe heating scheme with an upper wiring option is the need to install a membrane tank outside the heated premises. The upper wiring does not allow the intake of technical water for domestic needs, as well as connecting the expansion tank to the tank for hot water used in everyday life. This scheme is not suitable for flat-roofed residential properties.
Summary
The selected type of heating for a private house should provide all the inhabitants of the residential building with the necessary comfort. Save on heating is not worth it. By installing a heating system in your house that does not meet the parameters of a residential facility and domestic needs, you run the risk of spending a lot of money on refurbishment in the future.
Two-pipe or one-pipe heating system - the choice should always be justified, both from a technical point of view and from an economic one.
