Abstract (en)
[origin: EP2626640A2] A heat pump hydronic heater of the present invention comprises a heat pump heat source 1, a water-refrigerant heat exchanger 4 which exchanges heat between circulating water and a refrigerant heated by the heat pump heat source 1, a circulation pump 6 which circulates the circulating water heated by the water-refrigerant heat exchanger 4, a hot water tank 3 in which supply-hot water is retained, hot water supply heat exchanger 5 which exchanges heat between the circulating water and the supply-hot water, and control means, and the control means repeats, a plurality of times, stop of operation and restart of the operation of the heat pump heat source 1, thereby heating the supply-hot water. Therefore, even if the hot water tank 3 having an existing hot water supply heat exchanger is used, it is possible to sufficiently rise a temperature of supply-hot water in the hot water tank 3.
