<P>PROBLEM TO BE SOLVED: To provide a hot water supply device capable of providing clean bathing by automatically replacing hot water in a bathtub. <P>SOLUTION: This hot water supply device H supplies the warm water in a hot water storage tank 20 having a prescribed temperature adjusted by a mixing valve 70 to the bathtub 60 through a secondary flow channel 55 as a reheating circuit, and can perform a reheating operation by heating the bathtub water in the bathtub 60 sucked from a bathtub returning pipe 58 by circulating the bathtub water to a heat exchanger 50 for reheating by operating a pump (pump for reheating) 56, and returning the bathtub water into the bathtub 60 from a bathtub going pipe 58. A draining device 100 is connected to a secondary circuit 55 between a discharge side of the pump 56 and a connecting section of the mixing valve 70, so that the bathtub water in the bathtub 60 is sucked from the bathtub returning pipe 58 by operating the pump 56, and discharged from the draining device 100. <P>COPYRIGHT: (C)2010,JPO&INPIT |
