<p><P>PROBLEM TO BE SOLVED: To provide an efficient storage type hot water supply device free of hot water runout for resupplying hot water into a bathtub and reheating it by using hot water stored in a hot water storage tank. <P>SOLUTION: The storage type hot water supply device comprises the hot water storage tank 2 for storing hot water, a hot water filling pipe 29 for dropping the hot water in the hot water storage tank 2 into the bathtub 6, a bath circuit 22 connected to the bathtub 6, a bath circulation pump 20 for circulating hot water in the bathtub 6 into the bath circuit 22, and a reheating heat exchanger 18 for heat exchanging the hot water in the bathtub 6 circulated into the bath circuit 22 with the hot water in the hot water storage tank 2. It has an automatic water resupply means 39 for automatically resupplying hot water whose temperature is somewhat higher than a bath set temperature via the hot water filling pipe 29 to hold a water level in the bathtub 6 as set and an automatic hot insulation means 41 using the heat exchanger 18 for reheating the hot water in the bathtub 6 to be kept at a temperature somewhat lower than the bath set temperature. Thus, the efficient storage type hot water supply device free of hot water runout is obtained. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
