<P>PROBLEM TO BE SOLVED: To provide a heat pump type hot water supply device capable of simplifying a structure without causing the insufficient supply of hot water. <P>SOLUTION: Since a hot water storage temperature sensor 16 is provided only in one location in the vertical direction of a hot water storage tank 10, the number of wires of the hot water storage temperature sensor 16 can be reduced. Thus it becomes unnecessary to dispose the other control unit to connect the hot water storage temperature sensors 16 in a tank unit 60 which enables the simplification of the structure and cost reduction. Here, since a boiling operation is performed when a detection temperature of the hot water storage temperature sensor 16 becomes lower than a prescribed hot water storage temperature, and the boiling operation is also performed at prescribed time intervals even if the detection temperature of the hot water storage temperature sensor 16 is higher than the prescribed hot water storage temperature, the insufficient hot water supply can be prevented without detecting an amount of remaining hot water by disposing the plurality of hot water storage temperature sensors 16 in the vertical direction of the hot water storage tank 10, and a sufficient hot water supply amount can be constantly secured. <P>COPYRIGHT: (C)2013,JPO&INPIT |
