In the northern latitudes, the use of geothermal heating systems is advisable and advantageous only where the soil does not freeze too deep or is heated by faults in the earth's crust.
The benefits of geothermal heating
In 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 of small settlements. Nevertheless, technologies are developing, and as an additional source of heating, geothermal is quite suitable for central Russia.
Already today there are lots 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 light frost, completely switch to an alternative energy source.
The principle of geothermal heating
The principle of geothermal heating is based on the use of earth heat. Soil temperature at a depth of several meters never drops below +3 degrees. Heat pumps, which are the "heart" of a geothermal installation, take this heat and amplify it. Therefore, the deeper the heat exchangers are laid and the higher the temperature of the soil, the more efficient the system will work. The 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, up to 20 meters of wells are drilled in the soil. You can lay the pipe horizontally by digging a trench below the level of soil freezing. However, this is serious physical work. Therefore, almost no one equips geothermal heating with their own hands.
Do-it-yourself video of geothermal heating can be found online. However, these are usually small installations, the heat exchanger of which is lowered into a nearby body of water. Similar placement of it is also possible. But to heat a house of medium or large size with the help of such a installation will not work.
If you study the video of geothermal heating provided by companies specializing in installation of plants, the scale of construction work becomes immediately 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.
