In northern latitudes, the use of geothermal heating systems is advisable and profitable only where the soil does not freeze too deeply or is warmed up by faults in the earth's crust.
Benefits of geothermal heating
On the territory of the Russian Federation, the use of geothermal heating systems is beneficial only in the Far East and the Urals. Here, the heat of the earth would be enough even for heating and lighting small settlements. Nevertheless, technologies are developing, and as an additional source of heating, geothermal is quite suitable for central Russia.
Already today there are a lot of positive reviews about geothermal heating, working in combination with a gas or solid fuel boiler. This combination allows, according to reviews of geothermal heating, to seriously reduce the use of gas or coal. And in case of mild frost, completely switch to an alternative source of energy.
How geothermal heating works
The principle of operation of geothermal heating is based on the use of the heat of the earth. The soil temperature never drops below +3 degrees at a depth of several meters. The heat pumps, which are the “heart” of the geothermal plant, absorb this heat and amplify it. Therefore, the deeper the heat exchangers are laid and the higher the soil temperature, the more efficient the system will work. The working principle of geothermal heating is very simple. But the installation of geothermal heating with your own hands is almost impossible. Why - we will analyze further.
To lay a heat exchanger, deep wells are drilled in the soil, up to 20 meters. You can also lay the pipe horizontally by digging a trench below the freezing level of the soil. However, this is also a serious physical labor. Therefore, almost no one equips geothermal heating with their own hands.
A video of self-assembled geothermal heating can be found on the net. However, these are usually small installations, the heat exchanger of which is lowered into a nearby body of water. Such placement is also possible. But it will not be possible to heat a medium or large house with high quality with the help of such an installation.
If you study the video of geothermal heating provided by firms specializing in the installation of installations, the scale of construction work immediately becomes clear.
Despite the fact that the equipment for geothermal heating is very expensive, and its installation will cost a pretty penny, this is a very promising area of energy.
