Heat pumps use free natural energy of soil, underground water or air. In order to operate the heat pump itself only electrical energy is necessary that powers the compressor (also energy for the fan when using air heat). In comparison to the old heating system you will achieve costs saving on heating of 60-75%. Heat pumps are full and comfortable heating even in our latitudes. In addition to standard heat pumps with a standard output temperature of 55 °C, there are also heat pumps available with an output temperature of 65 °C that are suitable also for radiator heating.
The principle of heat pump operation is opposite to the principle of a refrigerator which removes heat (from the inside) and passes it into the surrounding environment (room). Thus, the heat pump extracts heat from the environment and passes it into the house.
Heat pumps for domestic hot water heating are not in principle different from AIR-WATER heat pumps but they have lower performance. They are made as simple or compact units whose performance is sufficient to heat water in the tank. They use excess (residual/waste) heat from rooms (e.g. kitchen, bathroom, pantry, cellar) so these rooms are slightly cooled and dried.
The offer also includes multifunctional devices with an integrated tank (300 and 500 l) allowing additional heating from the solar system, or a compact device with a small ground collector ensuring the use of energy from the ground, similar to GROUND-WATER heat pumps.
