principle of one-pipe heating system and its features

main difference-pipe heating system is a serial connection of radiators.This return flow from one pipe radiator is connected to supply the next, thus forming a kind of chain.This approach to heating saves money on piping, however, requires more attention in the choice of heating equipment, and to the calculation.

To understand the features of one-pipe heating systems, it is enough to compare with the traditional two-pipe.First, what stands out so-called "Leningradka" - is a much longer duration of the path along which the water must pass before reheating.Technically, this is called a high hydraulic resistance.The other side of the issue - the heating efficiency of the outermost portion of the circuit.As the water passes on pipe system gradually cools, the long-range radiat
or may have a temperature close to room temperature.Another shortcoming of pipe system - it is practically impossible to organize the natural circulation of the coolant, which is why the network is critical to the availability of heating circulation pumps.

calculation of one-pipe heating system

In matters of general heat "from Leningrad" is not inferior to a two-pipe system, but there is a question about the organization of a uniform distribution of heat.To this end, each radiator is installed bypass - bridge between flow and return heater having shut-off valve.By adjusting the degree of opening of the bypass valves on the radiator, you can achieve the most uniform distribution of heat.

for one-pipe heating system is best to choose the boiler to adjust the burner flame in a wide range.Properly configured one-pipe system does not require frequent switching in the boiler, but can operate in a continuous heating of the coolant, which ensures additional savings.You must also pay attention to the section of the pipe: it should be permanent in its entirety, including the bypass.The diameter of the line selected on the basis of capacity radiators.

-pipe elements combined systems

most widely used one-pipe system has received as part of a combined heating networks.At arrangement of heating in rooms that do not have contact with the street, the use of such a system is most justified: it continues to operate effectively, without disrupting the distribution of heat throughout the scheme.Also, single-tube systems are common in conjunction with heating collectors: how they form several single pipe branches connected in parallel to the main highway.
