<P>PROBLEM TO BE SOLVED: To provide a heat pump hot water supply device capable of improving COP in boiling-up operation by a heat pump heat source, and reducing the running cost. <P>SOLUTION: This heat pump hot water supply device is composed of an intermediate temperature water reserving part 28 for reserving the water of intermediate temperature, of which the temperature is lowered by the radiation by a radiating means, and an intermediate temperature water tapping pipe 33 for tapping the intermediate temperature water, is mounted on the intermediate temperature water reserving part 28 for tapping the intermediate temperature water. Whereby COP in boiling-up operation by the heat pump heat source is improved by reducing the intermediate temperature water, and the running cost can be reduced. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
