When the hot water supply circuit to the bathtub is connected to the hot water supply circuit via a switch in the middle of the process, the hot water tap is opened on the other hand when the hot water setting device for hot water is being used to provide hot water at a temperature of 80°C, or when hot water is being poured at a high temperature. In such a case, close the switching device installed in the hot water supply circuit to the bathtub 10, etc., and switch the hot water temperature setting to the temperature setting for the hot water tap, so that hot water can be removed from the hot water tap without discharging low-temperature water into the bathtub. This prevents hot water from coming out at a high temperature of 80°C to prevent risks such as burns. In other words, by giving a minimum priority to the hot water supply temperature setting of the hot water in the hot water supply circuit which is branched into a plurality of branches, it is possible to always supply hot water more securely than from the hot water supply faucet.
