<P>PROBLEM TO BE SOLVED: To realize a bath water reheating device for a hot water storage type water heater preventing discomfort of a bather by providing a control means for reheating and cleaning without outputting high temperature hot water. <P>SOLUTION: A bath water reheating means 40 is provided with a flow control valve 42 adjusting a flow rate ratio of a flow rate of bath water in a bathtub communicated to a heat exchanger 41 side, and a flow rate communicated to a side bypassing the heat exchanger 41, a reheating control program 200a controlling the flow control valve 42 so that the bath water bypassing the heat exchanger 41 is mixed with the bath water communicated through the heat exchanger 41, and a second bath water temperature thermistor 46a detecting a water temperature of the bath water mixed by the flow control valve 42. The reheating control program 200a controls the flow control valve 42 so that the water temperature detected by the second bath water temperature thermistor 46a does not exceed a predetermined temperature during reheating operation. By this, reheating can be carried out without discomfort of the bather. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
