<P>PROBLEM TO BE SOLVED: To provide a bathtub waste heat recovery controlling system for controlling hot water in a hot water storage tank to efficiently recover heat remaining in a bathtub, which has been disposed of. <P>SOLUTION: This bathtub waste heat recovery controlling system can reduce electric power for boiling up hot water in the hot water storage tank by supplying hot water of high temperature stored at an upper section of the hot water storage tank to the bathtub, and utilizing the heat of the hot water remaining in the bathtub. The hot water storage tank can efficiently store the hot water of high temperatures at its upper section, and can supply the hot water of high temperatures to a hot water supply section and the bathtub. A first heat exchanger is disposed at the upper section in the hot water storage tank to reheat the hot water in the bathtub to a high temperature. A second heat exchanger is disposed at a lower section in the hot water storage tank to heat the hot water at the lower section of the hot water storage tank by reutilizing the heat of the hot water remaining in the bathtub to utilize the waste heat. <P>COPYRIGHT: (C)2010,JPO&INPIT |
