Leningradka or collector heating system. Leningradka heating system in a private house

"Leningradka". There are several varieties of such structures, each of which differs in its structure and level of heat transfer.

What are the features of Leningradka?

As a rule, any version of the “Leningradka” is installed in buildings with one or two floors and a small area. The standard design diagram is a chain of, united by a single pipeline through which the coolant circulates. It is usually water or an antifreeze mixture. The heating device in this system is the boiler.

Despite the simplicity of the design, the Leningradka has a number of advantages over its analogues, especially when it comes to building it yourself:

ease of installation;
reliability during operation;
availability of the equipment used;
the ability to regulate the temperature on each;
economical use of coolant.

In addition to the advantages of installation, there are also negative aspects when using this system. The main ones are considered to be uneven heating of the initial and final radiators in the circuit, as well as the inability to connect additional equipment.

Varieties of "Leningradka"

Vertical connection.

Horizontal connection.

Depending on the location of the risers, the Leningradka is divided into horizontal and vertical schemes. The first is used for one-story houses, and the second is installed in buildings with two floors.

According to the method of coolant movement, this heating system can be with natural or forced circulation. The natural movement of liquid along the circuit is carried out due to the specific location of the heating element, expansion tank and pipes. As a rule, the circuit through which water circulates is installed at an angle.

Forced movement of the coolant is ensured using a special pump, which is built into the structure. Typically, this device is mounted in a circuit that is responsible for directing the fluid back into the system.

In addition to the above, the Leningradka heating system is divided into open and closed types of construction.

Open type of heating system

Single-pipe “Leningrad” with bottom connection of radiators.

The open-type Leningradka heating system is a design where the coolant from the heating device flows through a line into the first radiator in the chain, then into the next one, and so on to the final one. After which the liquid flows through the return riser back into the boiler and further along the same pattern.

This circulation process implies that the volume of coolant increases when heated, and accordingly, its excess must be discharged into a special device.

For reference! In an open-type Leningradka, this function is performed by an expansion tank, which is equipped with a pipe. It is with its help that excess liquid is drained during excessive heating.

When connecting radiators to the system, methods such as serial, diagonal and parallel can be used. The last of them is considered the most optimal option, since each radiator is connected separately to the riser, which allows it to be dismantled if necessary, without completely turning off the heating structure.

"Leningradka" closed type

Scheme of the "Leningradka" closed type.

This scheme involves the installation of a membrane expansion tank, which creates an excess pressure within the structure within 1.5 atmospheres. A closed type system requires the installation of additional equipment, such as a pressure gauge, air vent and safety valve.

Installation of the heating structure "Leningradka"

Before you start building a heating system for a private house with your own hands, you need to perform a competent and accurate calculation. It will be problematic to do this on your own, so it is better to turn to professionals in this industry. Using calculations, you can determine the list of equipment and materials needed for the work.

The main elements of the “Leningradka” include the following:

boiler for heating the coolant;
metal or polypropylene pipeline;
(batteries);
expansion tank or tank with valve (for an open system);
tees;
a pump to ensure coolant circulation (in the case of a forced design);
Ball Valves;
bypasses with needle valve.

In addition to calculations and purchasing materials, you should also take into account the location of the pipeline. If you plan to install it in a wall or floor, you will need to prepare special niches - grooves, which should be located along the entire perimeter of the contours. In addition, all pipes must be wrapped in thermal insulation material in order to prevent the temperature of the liquid from dropping before entering the radiators.

Important! If a heating system with natural circulation is installed, the supply pipe and main must have a slope of 2-3 mm per 1 m in the direction of movement of the coolant. In this case, the batteries are mounted in a flat horizontal position.

What is the best material to choose for the pipeline?

Most often, polypropylene is used as a pipeline for installing Leningradka in a private house. This material is quite simple to install and inexpensive. However, experts do not recommend installing polypropylene pipes in regions where the air temperature drops too low, meaning the Northern Territories.

Polypropylene begins to melt if the coolant temperature rises above 95 degrees, which can lead to pipe ruptures. In such cases, it is more advisable to use metal analogues, which are rightfully considered the most reliable and durable.

In addition to the material, when choosing a pipeline, it is important to choose the correct cross-section. In this case, the number of radiators used in the circuit is of no small importance.

For example, if there are supposed to be 4-5 elements in the circuit, then the diameter of the pipes for the main should be 25 mm, and for the bypass this value changes to 20 mm. Thus, the more radiators in the system, the larger the cross-section of the pipes. This will make it easier to carry out balancing when starting up the heating structure.

Connection of radiators and pipes

Installation of Mayevsky crane.

Bypasses are manufactured together with bends and then installed into the main line. In this case, the distance maintained when installing the taps must have an error of 2 mm so that the battery fits when connecting the structural elements.

The play that is allowed when pulling up an American woman is usually 1–2 mm. The main thing is to stick to this value and not exceed it, otherwise it may go downhill and a leak will appear. To obtain more accurate dimensions, you will need to unscrew the valves located in the corners of the radiator and measure the distance between the couplings.

Attention! All system radiators must be equipped with Mayevsky taps.

Starting a heating structure

Before starting the Leningradka heating system, it is necessary to open the Mayevsky taps installed on the radiators and release the air. After which a control inspection of the structure is carried out for the presence of flaws. If they are found, they should be eliminated.

After starting the equipment, all connections and components are checked, and then the system is balanced. This procedure means equalizing the temperature in all radiators, which is regulated using needle valves. If there are no leaks in the structure, no unnecessary noise and the rooms heat up quickly enough, the equipment is installed correctly.

The Leningrad heating system for a private house, although outdated over time, has changed, but is still widespread, especially in buildings with small dimensions. It is easy to install it yourself, while saving money on hiring specialists and the equipment necessary for construction.

It's no secret that during the Soviet Union, the construction of residential buildings was carried out constantly. At the same time, high-rise buildings were erected in record time. However, quite quickly the country’s leadership realized that such a pace of construction required a significant investment of funds - and during the development period it was quite difficult to allocate the necessary amounts.

Therefore, it was decided to try to reduce the cost of new projects as much as possible. The reform affected quite a few stages of house construction, but the most tragic consequences were the decision to simplify the heating system - and houses in which heating was carried out through just one pipe began to be put into operation. That is, the elements that were used to supply waste water were completely removed.

The Leningradka heating system is characterized by simplicity

Undoubtedly, such a system, the Leningrad heating system, had, according to the developers, a number of advantages. First of all, it required significantly less materials, and, moreover, was easier and faster to install.

Features of Leningradka

A single-pipe system, or Leningrad heating system, is a closed circle consisting of a special heating boiler and a ring of heating pipes. You can connect any number of registers or batteries to such a ring - and it will work just perfectly. At the same time, it was especially important for the designers that the installation of a heating system of this type is as simple as possible. For a more aesthetic appearance, the pipe was located close to the floor.

Components of the Leningradka with forced circulation

Quite often, a single-pipe heating system is called Leningrad, since it was first installed in this city. The Leningrad heating system (adjacent photo) shows that this is a fairly practical and convenient solution, which, however, has one rather serious drawback. Water heating Leningradka is not suitable for installation in one-story houses. More precisely, it can be installed, but full operation can only be achieved by supplementing it with a special accelerating manifold.

However, the accelerating collector, in turn, cannot be installed in houses whose ceiling height does not reach 2.2 meters. The fact is that it will interfere with the installation of the expansion tank and makes it impossible to connect it to the supply tank of the water supply system (meaning an autonomous system).

When installing a heating system, the accelerating manifold is an extremely important element. It is necessary to increase the speed of movement of the coolant (in this case, water in the pipes). In addition, the use of a collector significantly reduces the noise level generated during system operation. However, it should be borne in mind that in order to achieve maximum effect, the collector must be installed at the highest point that the architecture of the building allows.

It should be noted that those who plan to install this Leningrad heating system in a two-story house do not encounter a similar problem. After all, the height of the system is sufficient to ensure silent operation even without connecting an accelerating manifold or circulation pump.

The main difference between a single-pipe heating system is that it does not have a pipe through which the “waste” water flows out. However, it is not uncommon to find a conditional division of single-pipe heating in Leningrad into a supply pipe and a return pipe. In this case, the supply pipe is the first half of the main pipe. But its second part is called the return pipe.

Connecting heating batteries in Leningradka

Heating Leningradka (video below) will show that such a system is often a small element of a two-pipe system. In addition, the Leningrad system is perfect for heating houses and buildings of varying architectural complexity. At the same time, its significant advantage is the ability to lay heating pipes below floor level. However, if you decide to install the pipe in the floor, you should take proper care of the insulating materials. They are necessary in order to minimize the level of heat loss. In addition, through thermal insulation it is necessary to prevent heating of the subfloor.

Disadvantages of the Leningrad system

A significant disadvantage of a single-pipe system is that, if necessary, you will not be able to control the heating level separately for each of the radiators connected in series. Individual control is only available in a two-pipe heating system. And in the Leningrad heating system, by reducing the heating level of the battery using a valve, you automatically reduce it in subsequent connected radiators.

Another rather serious drawback of the Leningrad heating system scheme, reviews show that for efficient movement of the coolant, the installation of a pump is necessary.

For the heating system to function properly, there must be constant high pressure in the pipes. And if you increase it by introducing additional equipment into the system, this is fraught with a decrease in the service life of materials. That is, the amount of water seepage (breakthroughs) increases, which, in turn, requires replacing the pipe to replenish the amount of water in the heating system.

It should be noted that in a two-pipe system there is no need for an additional pump, since the water circulates independently - its own pressure is enough for it.

The third, and perhaps the most significant drawback of the Leningrad system is that it requires exclusively vertical spilling. That is, the expansion tank should be installed only in the attic.

And in one-story residential buildings, sometimes the attic is a very necessary functional space, in which it is quite difficult to allocate space for a tank.

"Leningradka" in a one-story house

Installing a system such as the Leningrad heating system in multi-storey buildings reveals another drawback. The heating element is located at the top point of the system - which means that with each radiator, as it goes down, the coolant gradually cools down. That is, the radiators on the first floor of the house will be less hot than on the last. The solution to the problem is the use of additional jumpers, and, in addition, an increase in the number of battery sections on the lower floors.

Positive aspects of the Leningrad heating system

Of course, any heating system (and the Leningrad heating system is no exception) has a number of positive properties, the number of which significantly exceeds the negative aspects in installation and operation. First of all, it should be noted that most of the shortcomings in the functioning of a single-pipe heating system were quite serious only during the period of its inception. Modern technical means easily cope with them, making Leningrad heating very popular. It is especially popular when creating a heating system for private houses.

One of the most significant advantages of the Leningrad system is its cost.

The fact is that to obtain a fairly long line, significantly less materials will be required than when installing a more complex two-pipe system. So the cost savings when you choose a Leningrad water heating scheme are obvious.

Options for "Leningradka"

In addition, a significant advantage is that today the issues of heat loss during the operation of such a system as the Leningrad heating system, pros and cons, you will understand that this can be solved using modern technological means. Installing additional ball valves, balancing valves, air vents, and thermostatic sensors increases the efficiency of the system.

Also today, a sequential coolant supply scheme has been developed for single-pipe heating systems. Thanks to its introduction into Leningradka-type heating, it became possible to reduce the heating level of an individual radiator. At the same time, the temperature in the remaining batteries in the network does not decrease.

Often, when planning a heating system, many turn their attention specifically to Leningrad heating, the system of which looks more neat and aesthetically pleasing.

From all of the above, we can draw a simple conclusion - based on the described disadvantages and advantages of the system, everyone can independently decide how appropriate it is to install a single-pipe heating system in a private house.

During the period of global housing construction in the USSR, Leningrad engineers proposed one of the single-pipe heat supply schemes, which could significantly reduce the costs of its creation, as well as reduce the time it takes to put houses into operation. This led to its widespread use during that period. But even after half a century, the Leningradka heating system remains in demand, especially in low-rise housing construction.

Of course, since its inception, this option for heating premises has undergone a number of modifications, but the basic principles of its creation and operation, as well as its undeniable advantages, have remained virtually unchanged, which attracts many developers when choosing an effective and budget-friendly heating method.

Generalized diagram of a single-pipe "Leningrad"

In general, this circuit is a closed circuit consisting of radiators connected in series through a single supply line, starting their work from a heat source (electric or gas boiler) and closing on it.

The heated coolant, which in most cases is used as water, circulates through the system and, passing through each installed heating device, gradually releases its heat.

As is known, when the temperature increases, a liquid, increasing in volume, begins to flow and is capable of rising to a certain height. Therefore, the water leaving the boiler fills the entire system, and subsequently displaces the cooled coolant from it. At the same time, the cooling and heating processes occur constantly, which ensures continuous circulation of the liquid even without the use of special equipment.

To maintain the required pressure in the system, the scheme provides for the presence of an expansion tank, for which a separate riser is installed in the immediate vicinity of the heat source.

Figure 1 – Generalized diagram of the “Leningradka”

The diagram presented above proves that “Leningradka” is the simplest system in design of all existing systems, which allows one circuit to provide heat to the entire floor and which can be easily installed on your own.

Among others her advantages should also be indicated:

relatively low cost, because its installation requires less pipes and less execution time;
availability of materials and components;
reliability;
efficiency for low-rise housing;
ability to connect to several different types of heat sources;
ease of setup and operation.

Disadvantages of the system and possible ways to eliminate them

Like any heating system, the Leningradka is not without its drawbacks. However, today there are ways to eliminate them.

The first drawback is related to the principle of its operation: as you move away from the heat source, the temperature of the radiators becomes lower and lower, and, accordingly, the rooms will be cool.
This problem can be solved by increasing the number of sections or the area of heating devices in each subsequent insert.
Another option to ensure balance, i.e. uniform heating to the required temperature is the installation of shut-off and control valves: taps, cone valves, regulators, thermostatic valves, bypasses, etc.
Another imperfection of such a system (in the classical version) is the impossibility of regulating the temperature and repairing one of the elements without completely stopping its functioning. However, currently such a scheme is found only in old houses. Modern options already include the installation of the above equipment, which allows you to change the degree of heating of each specific radiator, as well as its replacement without affecting the operation of others.
The use of metal pipes not only increases the cost of the Leningradka, but also complicates its installation and repair. The way out of this situation is to use metal-plastic or polypropylene pipes.
However, it must be remembered that the sections of the line in contact with the boiler must be made of metal.
Like any single-pipe system, for effective operation the Leningradka requires increased coolant pressure in the pipeline. This problem can be eliminated either by increasing the heating temperature of the liquid, which is not always acceptable, or by installing a circulation pump.

Existing modifications of the Leningradka single-pipe heating system

The design feature of this heating option allows it to be performed in two versions: horizontally And vertically.

Horizontal scheme

In this case, the contour is laid along the perimeter of the building (floor). In this case, the supply line can be located both above the floor covering and directly in the floor structure. In the second method, it is recommended to insulate the heating pipeline to eliminate heat loss.

Figure 2 – Horizontal diagram of a single-pipe “Leningrad”

It is necessary to take into account that when choosing a hidden laying of the supply line, you should carefully calculate the number of radiators and their required parameters, as well as correctly determine the locations of their connections and install all elements with high quality, because Any modifications or repairs to the system will require removal of the floor covering.

Figure 3 – “Leningradka” with the location of the supply line in the floor structure

A horizontal heating scheme can be carried out open or closed.

Open type provides for the installation at the top point of the system of an expansion tank communicating with atmospheric air. "Leningradka" closed type eliminates this possibility, so it uses a membrane tank, which is installed in the same room where the heat source is located.

Vertical scheme

This design is similar in design to the traditional single-pipe system used in multi-storey buildings: radiators must be placed one under the other and connected to a single pipeline. The difference is that the coolant does not move along one riser (i.e. only from top to bottom), but along a circuit (heated water first rises to the upper floor, passing through installed appliances, and then descends to the lower level, passing through the second group of radiators ).

Figure 4 – Vertical diagram of the “Leningradka”

It must be remembered that a vertical system with natural circulation is capable of functioning with a total circuit length of no more than 30 m. Otherwise, the installation of a pump is required, the power and, accordingly, the cost of which will depend on the number of storeys of the building. Therefore, this scheme does not apply to houses with more than three levels.

Possible options for connecting heating devices

Based on the design features of the Leningradka single-pipe system, there are the following options for connecting radiators:

one-sided lower (saddle)– used in a horizontal scheme; The supply and removal of coolant is carried out at the bottom of the devices;
Figure 5 – Bottom (saddle) connection of the radiator to the system
diagonal– the coolant is supplied from above, and discharged from below; such a connection ensures more uniform heating of devices, saves up to 15% of heat and can be used in both horizontal and vertical systems;
Figure 6 – Diagonal battery connection in a horizontal system

Figure 7 - Diagonal connection of equipment in a vertical system
side connection– coolant is supplied from above and discharged from below on one side of the device; used only with a vertical heating scheme.
Figure 8 – Lateral connection of the radiator

It should be noted that the lower option for connecting radiators also has several modifications, differing in the configuration of the supply line (change in its diameter), as well as the presence of control valves. Each of them is designed to increase the efficiency of the system.

Figure 9 – Leningradka options with bottom connection of heating devices

Installation technology of “Leningradka” with a horizontal contour

Since, of all the possible options, the horizontal scheme with bottom connection of heating sources is especially popular, it is advisable to consider the stages of installation of this particular system.

One of the simplest, one might even say ingenious, heating systems is the Leningrad heating scheme, which received its name from the region (St. Petersburg) where it was invented. The simplicity of the system is the key to its reliability. Leningradka is extremely easy to install, and is used even in multi-storey buildings. If you have the tools and certain skills, you can easily install it yourself. To install the Leningradka, a minimum of materials is required; it can operate by gravity in buildings up to 30 meters high.

A single-pipe heating system in a private house in Leningrad is convenient, first of all, because it is very easy to select the operating mode of any radiator. Heating radiators are connected in parallel to one pipe, so you can even turn off or dismantle any radiator without disturbing the operation of the system.

For small houses and cottages, a system with gravitational (natural) water circulation is popular. In one-story houses, horizontal routing of risers is chosen. For multi-storey buildings, a combined scheme is used - vertical and horizontal installation of risers. As already mentioned, you can organize a “gravity” system or create a Leningrad heating system with a pump, which will significantly improve the dynamics of heating the premises.

"Leningradka" with natural circulation

System o This type of heating involves sequential installation of heating devices around the perimeter of the room. If a Leningrad heating system is used, the pipe diameters for “gravity” circulation must be used with a larger diameter. The basis of the system is that the boiler is connected to the first radiator, the output of the first radiator is connected to the input of the second, etc. From the last battery, the water that has given up its heat is returned through the return pipe to the boiler to repeat the cycle.

The popular and unpretentious Leningrad heating system can be installed with your own hands in two ways.

The first option is to connect heating batteries in series, and the second method is to use a diagonal connection of radiators to heat the batteries evenly. You can install any radiators, but when using traditional ones, the use of a Mayevsky tap is mandatory. It serves to bleed air from the batteries.

Parallel connection of batteries in the Leningradka heating circuit

The Leningrad heating system layout described above has one significant drawback. With this connection method, it is impossible to adjust the heat transfer of each battery and it is impossible to turn them off without stopping the operation of the entire system. To eliminate this drawback, a version of the Leningradka with parallel connection of batteries was invented.

With this connection, the input and output of the battery is regulated by a ball valve, and a valve is installed on a section of the riser parallel to the battery, acting as a shunt. The taps that shunt each radiator play a big role in setting up the entire system. With their help, the Leningrad heating system of a private house ensures uniform heating of heating devices.

"Leningradka" with an additional contour

If, when creating a project, the system length is too long or the configuration is complex, then in such cases an additional circuit is used. The additional circuit is connected in parallel to the main one. In order for the system to work correctly, a needle-type valve is installed on the “return” of the additional circuit to debug the heating system. The second important requirement is that the “return” of the second circuit, if a Leningrad heating system with a pump is used, must be connected to the return pipe of the main circuit to the pump

Leningradka version - closed system

Any heating scheme in a private house in Leningrad easily turns into a closed one
system. It is clear that in such cases it is necessary to install a membrane-type expansion tank, a pressure gauge, and safety valves for safety. When installing a wall-mounted boiler that has a built-in circulation pump, installation of a separate pump is not necessary.

This heating system for a private house in Leningrad is most often used in two-story houses.

The single-pipe Leningradka described above and its possible variants are very popular, confirmed by good reviews. This heating scheme can be used both in multi-storey buildings and in small private houses, cottages and cottages.

The main advantages of the system based on the practice of its application:

the system is easy and simple to install;
does not require expensive equipment;
Battery heating can be adjusted;
fits well into the interior of a two-story house;
main risers are easily hidden;
reliable in operation (if properly designed);
can work as a “gravity-flowing” system (correct calculation and proper installation).

Despite a fairly large number of practical advantages, the Leningrad heating system without or with a pump also has some disadvantages. It is up to the owner to decide how these shortcomings will affect the final choice of heating scheme, but these disadvantages exist:

some unevenness in heating of batteries, especially the first and last;
with a horizontal system it is impossible to connect a “warm floor”;
usually requires forced circulation, especially for a two-story house.

Useful tips for those who have chosen the Leningradka scheme:

Automatic control of heating system parameters

A servo drive is an automatic mechanism that provides the specified parameters of the coolant by sending a control signal to the mixer. The servo drive for heating works as follows. From a room thermostat or other sensors that record the temperature of the floor, coolant or air in the room, a signal is sent to the servo drive, which sets the mixer damper (three-way or four-way) to a position corresponding to the temperatures set on the sensors.

The floor temperature is adjusted, for example, by moving the mixer damper. This movement bypasses the heated floor circuit and redirects part of the coolant to the return line. Thus, the floor temperature decreases and when the minimum permissible temperature is reached, the servo drive turns on again, but this time it closes the damper, more coolant enters the circuit and the temperature increases to the set temperature on the sensor. The cycle repeats periodically.

One of the most difficult engineering problems that must be solved when designing and building individual housing is the design of the heating system. Quite often, the best choice for owners of a small house is a simple single-pipe water heating system known as “Leningradka”.

This system got its name from the city of the same name, where it was first used to heat apartment buildings. It was developed during the era of large-scale construction in the USSR to achieve maximum savings on pipe products. Since then, the original scheme has undergone several modifications, but its main advantages still attract many who want to organize budget heating of a private home:

minimal material consumption;
simple and straightforward installation, the ability to install it yourself;
availability of components;
inexpensive maintenance and repairs.

The photo below shows a diagram of the design of a modern Leningradka-type heating system. It is based on the principle of sequential connection of heating devices using a single supply line, which, at the exit of the last battery, passes into a return circuit, ensuring the cooled coolant is drained back into the boiler. Thus, the coolant, which is usually heated water or antifreeze, circulates in a closed system, giving off heat as it moves.

Wiring options

The heating system can be installed in two different ways: with a vertical or horizontal arrangement of the main line.

The vertical system is practically not used in apartment buildings, since it makes it difficult to keep individual records of heat consumption. For a private home, on the contrary, it is more preferable, since it provides simple installation and more efficient heat transfer.

Difference between open and closed heating systems

In open water heating systems, an expansion tank is installed at the highest point, which is connected to the atmosphere. Thus, the open type circuit provides for the movement of the coolant in accordance with the laws of physics: the heated liquid rises upward, displacing the cold one.

Closed systems require the presence of a membrane tank that maintains internal pressure in the line. Such a tank does not have to be located on top, so it is usually installed in the same part of the house where the boiler is located. This is described in more detail in the video clip.

Connecting heating devices

Radiators, which are used to heat the premises of a private house, can crash into a pipe in two ways.

It is necessary to install ball valves at the inlet and outlet of the radiator, which will allow you to disconnect the device from the main line if it needs to be repaired or replaced.

In order not to disrupt the operation of water heating at home, all radiators must be equipped with a bypass, which will ensure the supply of coolant bypassing the battery when it is turned off. Inserting a special needle valve into the bypass, which allows you to partially block the cross-section of the pipe, will make it possible to regulate the degree of heating of each battery separately and will significantly increase the efficiency of the entire system as a whole (see our video below for more details).

Features of installation of the Leningradka system

In private low-rise construction, open-type Leningradka single-pipe water heating systems with horizontal wiring are most often used.

This scheme assumes the presence of a boiler to which a line is connected that supplies the connected batteries with coolant. A vertical riser is installed not far from the boiler, at the upper end of which an expansion tank is installed, which is necessary to equalize the pressure during expansion or compression of the liquid and to remove excess air from the system.

Diagram of the Leningradka open type heating system

Connecting radiators must be carried out taking into account the recommendations given in the previous section. A detailed overview of all the features of the design and installation of the Leningradka system is contained in the video fragment shown there.

In low-cost systems, coolant circulation occurs due to the displacement of cold liquid by warmer liquid. If funds allow, a circulation pump can be built into the return line, and the open expansion tank can be replaced with a membrane one. The closed system obtained in this way will make water heating of the entire house more efficient and economical.

Advantages and disadvantages of the Leningradka system

We have already cited the main advantages that Leningradka provides when organizing a water heating system - it is cost-effective, uncomplicated installation and ease of maintenance. At the same time, single-pipe systems also have a number of disadvantages:

the last radiators in the heating circuit must have a larger number of sections, since the coolant enters them cooled;
inability to connect heated floors or heated towel rails;
higher coolant pressure.

However, such disadvantages are characteristic mainly of traditional single-pipe schemes, in which adjusting elements are not used. The organization of bypasses with needle valves allows you to regulate the thermal conditions of each battery separately, providing the necessary flexibility and efficiency of water heating.

The modern modification of the Leningradka system is an excellent choice for heating a wide variety of rooms. We hope that this article and the photo and video materials contained in it will help you design a reliable and efficient heating system for your home.
