<P>PROBLEM TO BE SOLVED: To provide a technology capable of supplying clean hot water to a hot water supply part with a simple constitution in a hot water supplying device using both of a heat pump and a combustion device. <P>SOLUTION: This hot water supplying device comprises a hot water storage tank 126 for storing hot water, the heat pump 200 absorbing heat from the atmosphere and heating the water, the combustion device 102 for heating the water by burning a fuel, a heat exchanger 138 for heating clean water by heat exchange with hot water, and a hot water supply tube 194 for supplying the clean water heated by the heat exchanger 138 to the hot water supply part. The hot water in the hot water storage tank 126 is supplied to the heat exchanger 138, before the hot water in the hot water storage tank 126 runs out, and the hot water successively passing through the heat pump 200 and the combustion device 120 is supplied to the heat exchanger 138, after the hot water in the hot water storage tank 126 has run out. <P>COPYRIGHT: (C)2008,JPO&INPIT |
