Single-pipe heating system of a private house

The problem of autonomous heating in private houses is quite acute. This issue is solved by one of several ways of routing the pipes. One-pipe heating system is recognized as the most effective, as it is cheap, and its installation is not particularly difficult. It is worth considering it in as much detail as possible.

Single-pipe heating system: basic elements

The standard version is a closed ring, in which the following constituent elements are present:

• Boiler as the main heating device;
• Water as a coolant;
• Radiators;
• The expansion tank, which serves to regulate the pressure of the circulating system;
• Piping;
• Shut-off and control valves;
• Drainage taps.

Single-pipe heating system: operating principle

The heat-supplying pipe comes from the boiler, is placed around the perimeter of the whole house, and then returns in the form of a return. The connection of the radiators in this case is carried out in series at the inlet and outlet. With the natural circulation of the coolant, the feed tube is usually placed under a certain slope in order to make a natural height difference. The coolant enters the first radiator, then into the second, and so on. Each battery is supplied with a tap to vent air. It is clear that the radiator, which is closest to the boiler, that is, the first, will be the hottest, and the closing circuit - the coolest. To ensure that the temperature in all rooms is leveled, the water supply pipes are equipped with taps designed to regulate the water supply.

If the battery, which heats up more strongly, reduces the pressure, then the coolant will be delivered to the next radiator more hot, as it will not lose energy to warm up the first device. Single-pipe heating system allows you to regulate the heat supply efficiently enough, so that in all rooms you can set approximately the same temperature. This should be taken into account when using it.

Calculation of single-pipe heating system

In the planning process, certain points must be taken into account. If the area of the room is large enough, then natural circulation will not be enough, it is required to plan the installation of an accelerating collector or a noiseless pump. When planning vertical wiring in two-story houses it is necessary to take care of sufficient heat insulation of the attic space. On each pipe that goes to the central highway from the radiators, it is necessary to install a control and shut-off valve, which will allow controlling heat emission, and it will also be invaluable if you need to repair one of the batteries. If you are interested in single-pipe heating system, it is necessary to start calculating the heat costs for the entire heating plant to begin with - it is necessary that it be rational.

In conclusion, it should be said that if you chose this method of heating, then you should make installation and start-up operations in advance, that is, before the onset of cold weather.
