The problem of autonomous heating in private homes is quite acute. This issue is addressed through one of several pipe routing methods. The one-pipe heating system is recognized as the most effective, since it is cheap, and its installation does not present any special difficulties. It is worth considering it as detailed as possible.
Single pipe heating system: basic elements
The standard option is a closed ring in which there are the following constituent elements:
- a boiler as a main heating device;
- water as a coolant;
- radiators;
- expansion tank, used to regulate the pressure of the circulating system;
- pipe wiring;
- shut-off and control valves;
- drain taps.
Single pipe heating system: principle of operation
The heat- supplying pipe comes from the boiler, is placed around the perimeter of the whole house, and then returns as a return. In this case, radiators are connected in series at the input and output. In case of natural circulation of the coolant, the supply pipe is usually placed at a certain slope to make a natural difference in height. The coolant enters the first radiator, then to the second and so on. Each battery is equipped with a tap to vent. It is clear that the radiator that is closest to the boiler, that is, the first, will be the hottest, and the closing circuit will be the coolest. In order to equalize the temperature in all rooms, taps are installed on the water supply pipes to adjust the water supply.
If the pressure in the battery, which is heated more strongly, is reduced, the coolant will be delivered to the next radiator hotter, since it will not lose energy on heating the first device. The one-pipe heating system allows you to regulate the heat supply quite efficiently, so that in all rooms you can set approximately the same temperature. This should be considered when using it.
Calculation of a single pipe heating system
The planning process should take into account certain points. If the area of the room is large enough, then the natural circulation will not be enough, you need to plan the installation of an accelerating manifold or a silent pump. When planning vertical wiring in two-story houses, it is necessary to take care of sufficient thermal insulation of the attic. On each pipe that goes to the central highway from the radiators, it is necessary to install control and shutoff valves, which will allow you to control heat transfer, and will also provide invaluable service if you need to repair one of the batteries. If you are interested in the single-pipe wiring of the heating system, it is necessary to begin with calculating the cost of heat throughout the heating plant - it is necessary that it be rational.
In conclusion, it should be said that if you chose this method of organizing heating, then you should install and carry out
commissioning in advance, that is, before the onset of cold weather.
