"Leningradka" - systems, heating in which is built on a single-circuit principle

One of the most important issues in the construction of a private country house is the arrangement and installation of a heating system. The efficiency and speed of heat exchange of air and the reliability of the whole system depend on how well this issue is solved. If we correctly approach this aspect, we can make not just a pipeline capable of effectively heating the rooms, but also satisfying all the design moments in the interior of the room. And here, special attention should be paid to the type of heating that you will use. In this article, we will try to reveal all the features that the "Leningradka" system has.

Systems whose heating is built on the principle of single-pipe circuit

At the moment, there are two main ways of laying the pipeline. It can be a single-tube or two-pipe system. As for our "Leningradka", it refers to the first type of devices. This method of laying heating is one of the most popular and widespread in Russia today. And all because "Leningradka" (systems, heating in which is built on a single-loop principle) allow the owner to choose the heating time and in the same way serve it without involving any specialists. Thus, this type of pipeline provides absolute autonomy of the building from the central heating system.

What are the nuances?

The main nuance when using "Leningradka" is that it is not able to normally warm multi-storey buildings. Therefore, it is used mainly in single-storey buildings. Although, according to experts, with the right approach it is possible to provide effective heating of a room with two floors. But in this case it is best to use two-pipe systems. Their installation is more simple, and heating is more efficient.

This photo shows the scheme of the heating system "Leningradka":

As we can see, it uses only one pipe, which is gradually supplied to each of the radiators (batteries) and finally comes to the boiler, from where it starts to circulate again. The heating method here is closed, since the water flows in the system along a circle along a single contour with a certain feed rate and the amount of liquid.

What advantages does Leningradka have?

Systems, heating in which the single-tube, in particular, and "Leningradka", have a lot of advantages compared to other analogues. Firstly, thanks to the presence of just one pipe, it is possible to lay the pipeline in the most inaccessible places (for example, it can be a place under the doorway). Thanks to this, it is possible to hide excess pipes from the human sight, thereby not damaging the interior design of the room. Secondly, "Leningradka" is very easy to install, and when installing it, it is not necessary to call specialists. Thirdly, "Leningradka" (systems with single-circuit heating in which it is used in almost all Soviet-built housing units), due to the absence of a second row of pipes, is less expensive in financial terms for installation in comparison with a two-circuit one.

Among the shortcomings, we can only note its low thermal conductivity. Because of this, the single-tube heating system "Leningradka" is not used in multi-storey buildings.
