The problem of autonomous heating in private housesis 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 variant 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;
- Pipe wiring;
- shut-off and control valves;
- drainage taps.
Single-pipe heating system: operating principle
The heat-supplying pipe comes from the boiler, is placedon 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 supply pipe is usually placed under a certain slope in order to make a natural height difference. The coolant enters the first radiator, then 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 one, will be the hottest, and the closing circuit is the coolest one. To ensure that the temperature in all rooms is leveled, the water supply pipes are fitted with taps designed to regulate the water supply.
Calculation of single-pipe heating system
In the planning process, consideration should be given tocertain moments. If the area of the room is large enough, then natural circulation will not be enough, it is required to plan the installation of a boost 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 the heat transfer, as well as it will be invaluable if you need to repair one of the batteries. If you are interested in single-pipe wiring of the heating system, you must first calculate heat costs throughout the heating plant - it is necessary that it be rational.
