The Leningrad heating system is one that has endured the test of time when it comes to effectively heating a home. This approach, which is trusted and easy to use, has been applied for many years in residential construction. Because it provides a good mix between affordability and efficient heat distribution, it’s a well-liked option in many different climates. Knowing the layout and installation of the Leningrad system can be very beneficial, whether you’re thinking about installing a new heating system or remodeling an old one.
The central component of the Leningrad heating system is a single-pipe loop that joins each radiator in a structure. This design maintains uniform heating throughout the structure and makes installation and maintenance simple. Compared to more complex systems, it has fewer points of failure due to its simple design. For homeowners searching for a dependable heating solution that requires little continuous maintenance, this is wonderful news.
There are some important considerations to make if you’re thinking about installing this kind of system. To achieve even heat distribution, you should make sure that the radiator location and pipe arrangement are optimized. To achieve maximum efficiency, it’s also critical to use high-quality materials and appropriate insulation. Installing a Leningrad heating system that keeps your house toasty and cozy even in the coldest months only requires you to follow a few simple instructions.

Wiring options and the principle of action
A straightforward Leningrad heating system makes use of the special qualities of liquids, which soften and rise to a radiator when heated. In a one-story home, pipes are typically installed at floor level or beneath the floors to form the building’s perimeter. An extra heat source called hot pipe helps to heat the space more evenly. Therefore, freezing of areas away from radiators is not included. When properly calculated and installed, a single-pipe Leningrad heating system is sufficient for heating private homes and cottages.
The simplest one-pipe wiring scheme is being modernized by heating Leningrad, in theory. All radiators in a single-pipe system are connected in turn, and the coolant from the last battery is recycled back into the boiler for further heating. The system is extremely antiquated, and its primary flaw is the radiators’ uneven heating along the coolant’s path. The second disadvantage is that you have to turn off the heating system in order to replace or fix any radiator.
The uneven heating is negligible with a small number of radiators (no more than 5) if the system is installed as closed with a circulation pump. One-pipe plan. Larger diameter pipes can be used in conjunction with an open expansion tank to function as a gravitational force.
Modernized one -pipe scheme of Leningradka
How the batteries are connected to the supply pipe defines a single-pipe heating system with mandatory Leningrad circulation. In the direction that hot water moves through the pipe, radiators are cut parallel to it. The lower battery pipe is connected after the top of the radiator, though the lower connection can also be used. Lower connection: this is where the radiator’s input and output pipes are situated. Heating devices are uniformly heated by the coolant moving at a sufficient speed in the supply pipe. Thus, the heating system in a private residence in Leningrad is an easy-to-use and dependable one.
Additional heating is provided by the supply pipeline, which is positioned around the outside of the structure.
Convectors hidden in niches under large windows can be connected if needed. With the convector positioned horizontally, a unique pipe insert must be made in order for water to enter it during installation. It is welded into the supply pipe after being cut at a 45-degree angle. A portion of the water from the supply pipe branches off and enters the convector, creating resistance to the run-up stream.
Vertical one -pipe heating scheme
A vertical wiring scheme is used in multi-story buildings. After being exposed to the attic, the supply pipe is insulated. The supply pipe is lowered to reveal diting pipes. The floors’ batteries are connected in a sequential manner.
It’s crucial that the radiators are placed precisely in one vertical orientation during installation.
There are occasions when radiators on different floors are connected in parallel. The battery connection and the supply pipe are connected in parallel at the same time. The battery outputs are connected in parallel to a different pipe that is lowered and connected to the "Reverse" pipe. The components of the two-pipe system are distinguishable in this instance. This is a hybrid plan.
Leningrad diagram with natural circulation
A single-pipe heating system with natural circulation of Leningrad, in which water moves due to gravity, can be useful for small homes and cottages. Large enough diameter pipes must be used in order to arrange such a system. The increased volume of coolant and the bigger diameter of the supply pipe will lessen the hydraulic resistance and the uneven heating of the radiators. A second source of heat is provided by the pipe that is positioned around the outside of the space. It is essential to install pipes by following their inclination in the coolant’s direction of movement.
A straightforward and dependable heating system is easy to install and maintain. It is simple to update. It becomes feasible to change or fix batteries while installing bypasses, cranes, and valves without having to shut down the system. Following modernization, the Leningrad scheme permits the installation of the preferred temperature and the modification of the radiator return in various rooms.
The Leningrad heating system is a simple and efficient setup for residential heating, commonly used in homes and small buildings. Its design is based on a single-pipe loop that connects all radiators in a series, which can reduce installation costs and simplify maintenance. To ensure optimal performance, it"s crucial to carefully plan the system"s layout, considering the size of the building and the number of radiators. Proper insulation and regular maintenance will help maintain consistent heat distribution and energy efficiency. When installing a Leningrad system, make sure the radiators are balanced to prevent uneven heating, and consider integrating a bypass valve for better control. Overall, the Leningrad heating system offers a cost-effective solution for home heating with the right planning and upkeep.
Heating systems
There are two main types of options available on the system’s operation principle, despite their variety. They can be implemented in an apartment in the city or in your own home.
- Natural circulation – the coolant, as a rule, water, moves under the influence of gravitational forces and due to the difference in the temperatures of heated and chilled water. It will operate effectively, subject to some conditions: the total horizontal area of the system should not exceed 3500 kV m, and the heating boiler should be below the radiators by at least 3 m. If in a private house or apartment on the ground floor you can place a boiler in the basement, then this is the best option, judging by the reviews of consumers.
- Forced circulation – the coolant moves through the pipes due to the operation of the pumps.
Pipes are connected to the heating boiler using one of two circuits.
- One -pipe – the coolant moves one pipe to the radiator, partially cools in it and moves to the next. This option requires a lower length of the pipeline – about 30%, and is more easy to install. The installation of the system is quite feasible with your own hands. The most common heating option is Leningrad.
- Two -pipe – the coolant of the same temperature is supplied to all radiators in parallel one pipe, and returns along the other pipe from each radiator to the boiler. In such a system, all radiators heat up equally, and heating in the house will be more uniform. Also, the system allows you to regulate the heat transfer of each radiator separately.
Two turning styles, each with advantages and disadvantages.
- Vertical – feeding and abyting pipes are located vertically to each radiator. The scheme is recommended for compulsory circulation systems: a less powerful pump will be required, since partially the circulation is ensured by natural drainage of water from the highest point. This heating method is more often implemented in multi -storey buildings, where main pipes are located in attics or technical floor.
- Horizontal – pipes are located horizontally within the floor. The plus of the system is the ease of adjustment and overlapping. Horizontal wiring was implemented in Lenigradka. The photo shows a circuit with a horizontal scan.
Options for a single-pipe or two-pipe system with a horizontal scan are typically available for private homes. These systems are quite effective, simple to install, and easily repaired.

Some installation features
When building the system and completing it by hand, use the information from the Internet. Keep in mind that reading a lot of material and watching the video will increase your chances of finishing what has started. However, hiring a professional practitioner, at the very least, for consulting support, is the best way to organize heating on your own.
The number of their sections should be increased in order to guarantee the radiator chain’s extremes are heated to a high standard.
It is required to use pipes with a considerable diameter for the gravity version of the system. Additionally, the circuit’s overall length shouldn’t go over 30 meters.
The supply main pipe installation needs to be done beneath a slight slope. Since the radiators are positioned at the same height, the room’s "geometry" is not altered in any way.
Leningradka’s vertical wiring and a lengthy "horizontal" will inevitably need to be added to the circulation pump system.
When doing an installation by hand, keep in mind that the floor’s supply pipe needs to be warmed using heat-insulating roller materials. This will prevent the "underground" space from overheating and save you a substantial amount of money while the system is operating.

Cranes in the shape of balls
Only needle-type taps should be used as shut-off valves on bypasses and additional circuits within the system. They have the ability to easily modify the fluid flow through them. Since ball valves aren’t meant for "half-open" operation, using them in this situation is inappropriate. They can be totally open or closed. Their prolonged performance is only retained in these two positions. The network has a sufficient amount of videos on this subject.
To wrap up a lengthy digression, we would like to point out that a single-pipe "Leningrad" has been tried and tested for decades. A contemporary "upgrade" featuring a circulating pump and regulatory bypass cranes enables you to benefit from the true simplicity and low cost of a more sophisticated heating system. You can install it correctly with your own hands and enjoy the warmth and coziness of your own home during the winter months.
Adjustment of the heating system in automatic mode
A unique automatic device known as a servo controls the coolant temperature in the circuit by giving commands to the mixer. This device operates as follows: a thermostat or sensor placed in the room senses the temperature of the air, coolant, and floor of the building and transmits that information to the servo drive. According to the sensor, he then moves the shade of a three- or four-way valve to the proper position.
Specifically, the mixer’s damper shift allows for temperature adjustment of the steam. This causes the warm floor’s contour to overlap, allowing some water to fall into the return. As a result, the floor temperature drops. The servo drive activates once more and opens the damper to introduce hot coolant into the circuit as soon as it reaches the minimum value. This is a cyclical process.
Positive aspects and disadvantages of the Leningrad system
An individual pipe heating system has the following benefits:
- Low cost: the most important “plus” is that of all types of heating Leningrad is the least costly. Both pipes and reinforcement are required for it in minimal quantities. Expenses are also reduced for installation, which is the least laborious.
- Simple device: this quality is manifested not only during installation, but also at the design stage. If in the two-pipe system, due to improper calculation of the diameters, areas can be formed with weak circulation or even stagnation of the coolant (this phenomenon is called an effort), then when constructing a single-pipe system you can not worry about it-the working environment under any conditions will transmit through all radiators, since She simply has no other way.
- The possibility of hidden pipe laying: since the radiators are connected by only one pipe, it can be placed at any level (in a two -pipe system, the feeding line must be laid above radiators). Taking this opportunity, the pipe is often hidden in the design of the floor, but even simply laid along the skirting board it will not be particularly noticeable.
The most significant drawbacks of a single-pipe system—an uneven heating of the room and a high hydraulic resistance of the contour—have already been discussed. In certain situations, the latter situation prevents the system from having a heated towel rail.
The inability to individually adjust the heat transfer of radiators and to fix them without disconnecting the entire system is another of the "minuses."
Advantages and disadvantages of Leningradka
What are the benefits of a single "Leningradka" pipe for a private residence?
- A minimum of expenses for the modernization of the system;
- Uniform heating of the premises;
- The ability to adjust the temperature in the premises;
- Lack of costs for additional equipment;
- Easy in installation.
Not without certain shortcomings:
- The difficulty in expanding – you can increase the length, but within limited limits;
- The inability to connect warm floors – for this you need to lay a two -pipe system;
- Additional costs for the circulation pump – if you need to warm the building of a large area.
The Leningradka scheme can be justifiedly used in small private homes, despite its drawbacks. The costs associated with installing a closed system will be higher.
Types of the heating system of Leningrad
There are numerous benefits to the two-pipe heating system. Because the coolant temperature throughout the entire system is nearly constant, you can guarantee that the space is heated evenly. A two-pipe system’s drawback is its high cost, as it requires additional pipe purchases and numerous connections. However, it enables you to heat individual homes in any location.
Single-pipe heating systems differ from two-pipe systems in that they are easier to install and require less money.
It is not very sensible to build a complicated and costly two-pipe system if the household is small. The best option is to install a single-pipe system and save money. It will guarantee that every room is heated and lower installation costs. As we’ve already mentioned, a system like this will cause the rooms farthest from the boiler to be noticeably colder. This is because the radiators consistently cool the coolant, which is how coolant flows in such systems—a single pipe returns to the boiler.
How should I handle this situation? We advise utilizing a "Leningradka" one-pipe heating system with natural circulation. How is it different from pipe heating, the standard one? The problem lies in the fact that during standard heating, the coolant heats the pipes one after the other in a sequential manner. Radiator inputs and outputs in Leningradka are sealed with jumpers or bypas. What does it provide?
- The coolant flows not only through radiators, but also through jumpers – this compensates for a decrease in its temperature;
- It becomes possible to adjust the temperature in the rooms – the coolant flows only along the jumper, on the jumper and radiators, only through the radiators;
- Hydraulic resistance is reduced – the natural flow of the coolant improves.
In a small private home, the "Leningradka" heating scheme ensures that every room is heated evenly while conserving materials.
You should be cautious about completely overlapping the heating system when it comes to the jumper/bypass or heating battery. This is because it can cause the heating boiler to overheat and activate the automation that keeps it from breaking down.
A feature that sets Leningradka apart is a bypass, where it would be ideal to install the radiator taps and the crane.
When houses with a large area need to be heated, the Leningradka forced circulation heating system might be needed. For instance, you may have chosen to add a few more rooms to your home, but you do not want to invest in the cost of installing a two-pipe system. In this instance, increasing the coolant pressure in the system is your responsibility; a small circulation pump helps with this. What is he going to give?
- Improving the flow of coolant – it will be able to overcome the hydraulic resistance of pipes and compounds;
- More uniform heating – the water simply will not have time to cool, as it flows through pipes with increased speed;
- The ability to increase the maximum length of horizontal sections – the system will be able to warm the house of a large area.
Leningradka is comparable to two-pipe systems in terms of effectiveness, but this is only the case for small homes. Two-pipe heating is not competitive in large buildings.
The sequence of installation of Leningradka
The installation of such a device as the Leningrad heating system with your own hands does not require special skills. In order for everything to be mounted correctly, you should simply observe a certain sequence of actions. First of all, from the boiler it is necessary to lay pipes around the perimeter of the room (it is best to use a pipe whose diameter is 1.5-2 inches). Further – near the boiler, an element is inserted, to which the main pipe of the vertical line will subsequently be connected. The upper part of this segment is the place where the expansion tank should be installed. The last stage of installation includes the connection of radiators.
The boiler’s cutting diagram
In this instance, it forms a ring when it closes on a heating boiler. Simultaneously, another component needs to be cut close to the boiler into the highway. This is a pipe, and somewhere up there is unquestionably where an expansion tank needs to be.
Its presence in the system is crucial because it is meant to raise system pressure, which in turn influences the coolant’s speed and, in turn, the radiators’ heating capacity.
On the main highway, there are two different kinds of heating devices. Connecting to the trumpet of the lower batteries will accomplish this. The device can also be connected diagonally. That is, the radiator’s input and output pipes are situated at various heights.
A Leningrad heating system for a two-story building or a multi-story building can be installed by hand. DIY heating systems are incredibly practical and convenient, and they are ideal for practically any type of building.
What is the heating system of Leningradka
First, where did the name come from-"Leningrad"? Rumor has it – this is a consequence of the fact that a similar system was first used in construction organizations of Leningrad. However, it is very difficult to agree with such a peremptory statement – the heating system is so simple that it simply could not but be used in any other regions. Perhaps in the city on the Neva any technical regulations were developed, which then spread throughout the country? But one way or another, during the period of mass urban construction, especially in housing -type houses and in one – two -story social buildings, this heating system has become prevailing. This was explained by its maximum simplicity and maximum economy-to come up with something cheaper, probably it is simply impossible.
Thus, Leningradka is a single-pipe heating system where heat exchangers are arranged in series on a single looped line, giving the impression that the line is "strung."
The most basic schematic representation of "Leningradka"
As a result, coolant from the boiler (or the central heating input) was gradually routed through each radiator from start to finish. Since it is evident that he gradually lost his heating temperature, radiators nearer the boiler should always be hotter than those farther away, particularly if they are closer to the boiler in the line.
This kind of system can function both naturally (as illustrated in the above figure) and by forcing the coolant to move (as illustrated in the diagram below). The heating radiators are not particularly impacted by this.
One way to arrange "Leningradka" is by closed type.
When all heating batteries are positioned at the same level, one-story construction is most likely to use similar radiator wiring. Concurrently, the trunk pipe from the boiler that closes the contour is constantly situated along the floor. By the way, this makes setting it up covertly and decorating with a floor possible with little difficulty.
The traditional arrangement of "Leningradka" involves drawing the ring’s outline around the outside.
Nonetheless, "Leningradka" makes a lot of sense in a two-story home (wiring schemes for even three stories can be found online). It is true that forced circulation will be necessary in this situation because the coolant will naturally rise to a considerable height. However, this presents a number of challenges because a high-power boiler and precise measurement of the pipe diameters in both vertical and horizontal areas are needed. Furthermore, since it is simpler to cut the circulation pump into the circuit than to cut the pump into the circuit, the viability of this strategy in this instance will raise questions.
By the way, which expansion tank is used in this instance won’t matter all that much. Forced circulation "Leningradka" works well in both closed and open heating systems. Ordinary water and special antifreeze can be used as coolants if the circuit is set up using the closed-loop hermetic principle (more on this in a separate article of the portal).
For instance, the drawings depict the most basic schemes, which are incredibly uncommon in real life. This is for a reason that will become evident once you are familiar with the principal benefits and drawbacks of Leningradka.
One -pipe heating scheme
The video provides a more detailed analysis of the relatively simple equipment model used in the one-pipe heating scheme. It is necessary to lay the main highway, which will be branched, from the heating boiler. It then has the appropriate number of batteries or radiators on it. The highway that went through the entire house comes back and joins the boiler. Using this technique, hot water is circulated through the pipes to heat a private home evenly.
It is possible to change the hot water cycle so that it can be forced to run and that it can rotate at will. In addition, depending on the source of heated water, the heating scheme can be designed under either an open or closed type.
Even by the current heating design standards, a private home can currently install a single-pipe heating system. The addition of components like ball valves, balancing valves, thermal controllers, and radiator controllers is up to the owner. These gadgets will give a private home’s heating system a contemporary model of temperature control, which will improve overall comfort when using it.

First of all, the temperature in the low-supported rooms can be lowered. However, in order to prevent the room from plunging and to maintain the correct view, the regulator must always be set for a minimum indicator. Furthermore, it will be feasible to independently raise the temperature in the sleeping quarters or bathroom. You can also control the temperature of a specific radiator in modernized Leningrad, that is, independent of other heating appliances.
In addition to this sensible solution, a single-pipe heating system will incorporate a bypass-style circuit. The benefit of having such equipment is obvious given that fixing any one radiator will fix the heating system as a whole. Nevertheless, turning off the system is not required.
The principles of installation of a horizontal one -pipe system
Although installing a horizontal heating system in a private home is relatively easy, there is a subtlety to this process that needs to be considered during the design process: the line line needs to be positioned beneath the floor.
You must lay a highway either directly into or on top of the floor structure when installing a horizontal one-pipe system. The video will familiarize you with this scheme. If you select the first option, there will be too much heat transfer in this room, so you should consider insulating the heat that will come from the pipes.

Leningradka typically has this heating system installed on its surface if it is placed within the floor’s structure. If a single-pipe heating system is installed above the floor, the modification can be made right away while the building is being built.
In order to allow the liquid inside the pipes to circulate in the prescribed direction, the line line is situated beneath a slight slope. The heating radiators, however, are positioned at a fixed height. Moreover, Maevsky’s taps must be installed on them in order to allow air to escape the pipes prior to turning on the heating system.

Principles of installation of a vertical one -pipe system
When forced hot water circulation is required, the Leningrad system, which uses a vertical scheme to heat private housing, is put in place. One benefit of this kind of installation is that batteries heat up more quickly, even in cases where the main line consists of small pipes. However, a circular pump must be present for this scheme to function.
If there isn’t a pump of that kind (which isn’t included), hot water circulates on its own without help from outside sources. A system like this is the result of a particular installation, where the coolant circulates as a result of the most basic principles of physics: when temperatures rise or fall, a liquid with a changed density causes the masses to move.
Diagram showing a vertical heating system’s operation. To enlarge, click the image.
Such a heating system requires a line with a big enough diameter. Furthermore, it is installed at a specific angle. When installing a vertical heating system, careful planning is required to minimize the chance that it won’t cross the highway and arrive at the desired location. It has a maximum length of thirty meters.
