なく快適に利用できる。Action Consider the case where the set flow rate is changed while the user is using a shower or the like. The flow rate is adjusted by narrowing or opening the valve openings of the water side valve and the hot water side valve while keeping the temperature of the hot water currently being discharged at the set temperature. First, the amount of hot water and the mixing ratio of the amount of water are obtained from the supplied hot water temperature estimating means, the hot water temperature detecting means, and the hot water temperature setting means. Based on the temperature deviation between the set temperature and the hot water temperature currently supplied to this mixing ratio, the proportional calculation means is used to obtain the adjustment amount so that the optimum mixing ratio is obtained, and the change gradient of the temperature deviation is equal to or greater than the set differential value. If so, the differential calculation means obtains the adjustment amount of the mixing ratio based on the differential value of the temperature deviation, and the biasing amount ratio of the first and second drive means is obtained from the above adjustment amount and the mixing ratio. Then, the urging amount is determined from the obtained urging amount ratio and output. In this way, the flow rate can be adjusted while maintaining the optimum mixing ratio. Even if the user changes the set flow rate while using the shower, the user can comfortably use it without feeling uncomfortable such as hot or cold.
