<P>PROBLEM TO BE SOLVED: To provide a hot water supply apparatus that prevents the temperature of hot water in a bathtub from decreasing due to a heat recovery function during a hot water adding operation by a user. <P>SOLUTION: The hot water supply apparatus includes: a hot water storage tank 1; a bathtub 3; a heat exchanger 4 for exchanging heat between hot water in the hot water storage tank 1 and hot water in the bathtub 3; and a control means 18. The hot water supply apparatus has: a hot water adding operation mode for supplying hot water to the bathtub 3; and a heat recovery operation mode for recovering the heat of the hot water in the bathtub 3 to the hot water in the hot water storage tank 1 by the heat exchanger 4. The hot water supply apparatus puts priority on the hot water adding operation rather than the heat recovery operation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
