<P>PROBLEM TO BE SOLVED: To provide a hybrid hot water supplier capable of reducing the frequency of the operating state and the stopping state of a heat pump device when radiating the heat to a heat radiator. <P>SOLUTION: In the hybrid hot water supplier, a first control device 100 raises the heating capacity of a heat pump unit 1 to the value of the upper stage if the difference between the target outlet temperature of a heating medium of a heat exchanger 4 for heat radiation and the outlet temperature of the heating medium of the heat exchanger 4 for heat radiation is ≥5°C continuously for the first prescribed time. The first control device 100 lowers the heating capacity of the heat pump unit 1 to the value of the lower stage if the difference between the target outlet temperature of the heating medium and the outlet temperature of the heating medium is <1°C continuously for the second prescribed time. <P>COPYRIGHT: (C)2013,JPO&INPIT |
