The condensor unit of the heat pump is divided into two heat exchangers. The first heat exchangers takes care of the superheat, and some of the condensation heat of the coolant vapor of the heat pump, and heats the tap water to a temperature which is higher than the condensation temperature. The second heat exchanger condensor heats the radiator water to a temperature corresponding to the condensation temperature of the coolant vapor.
