In its principle, the heat pump operates as a cooling device the driving element of which is a spiral compressor. In its evaporator, the device takes out heat from surrounding environment cooling it thus down, and using driving electric energy in a condenser the heat is transferred into an environment with a higher temperature – heating water for example, that is then warmed up.
In transferring from the evaporator into the condenser, the heat increases by the heat transformed from driving electric energy in the compressor. In other words: the thermal energy produced by the heat pump is given by the sum of both input energies which means that it is always higher than the driving energy.
