When generation of microbubbles is requested, microbubbles are generated by the microbubble generating device while the bathwater is circulated in a water circulation circuit to supply the microbubbles to a bathtub (bubble supply operation). When the temperature of the bathwater is lowered during the bubble supply operation, reheating operation is performed in conjunction with the bubble supply operation (bubble reheating operation). At this time, when heating operation by a heat pump unit is being executed, heat pump direct reheating operation is selected as the reheating operation. When the heating operation is not being executed, hot water storage reheating operation is selected.

摘要： PROBLEM TO BE SOLVED: To provide a water heater detecting failure of a water temperature sensor without limiting a user's use of hot water. SOLUTION: The water heater includes a mixing valve mixing water from a water supply pipe with hot water from a hot water supply pipe to produce mixed water. Based on a water supply temperature TW detected by a water supply temperature sensor, a hot water supply temperature TH detected by a hot water supply temperature sensor and a target mixed water temperature Tg set by the user, an upper limit opening SU and a lower limit opening SL of an opening of the mixing valve for making a mixed water temperature correspond to the target mixed water temperature Tg for the purpose of calculation are calculated. A temperature control means calculates a control mixing valve opening Sc based on a deviation between the target mixed water temperature Tg and a mixed water temperature Ta detected by a mixed water temperature sensor. When the control mixing valve opening Sc is deviated from a range from the upper limit opening SU to the lower limit opening SL, it is determined that any one of the water supply temperature sensor, the hot water supply temperature sensor and the mixed water temperature sensor is abnormal.
