Geothermal energy is the result of solar radiation. It accumulates in the ground. This low-grade heat can be used to heat residential buildings. As a source of such energy, you can use: natural and industrial reservoirs; waste heat; geothermal probes. As you can see, geothermal heating and cooling. at home uses the natural warmth of the planet. The first systems of this type began to be used in the 70s of the last century. Now they are common in Western Europe, the USA, Canada. For example, in Sweden, the heat of the Baltic Sea is used to heat apartment buildings. Geothermal energy in our country is considered unconventional. The warmth of the globe is considered to be an alternative source. SYSTEM COMPOSITION A geothermal home heating system consists of a heat pump and a heat exchanger. In addition to them, this also includes a harmless and non-freezing liquid (antifreeze). It circulates through the circuit pipeline and collects the heat energy accumulated in the ground. In heat pump evaporators, the antifreeze energy is transferred to the refrigerant. As a result, it cools down by about 3 degrees. The temperature of the refrigerant is then increased using a compressor. Thermal energy from this substance is transferred through a condenser to the water circulating in the heating system of the house. It can also be used to heat domestic water in heat storage tanks. The efficiency of such a system largely depends on the local climate. More precisely - on the degree of warming up of the earth. With a low heat content in it, the building will not be able to heat. Soil temperature should not be lower than + 5- + 7 degrees. The most effective way is to connect to the "Warm floor" system.
