With such a configuration, for example, a temperature of about 60 ° C. is applied to the first usage section such as a bathtub that requires a relatively high-temperature hot water supply.
Hot water at a desired temperature of about 60 ° C. or lower can be supplied to a second use section such as a washroom or a kitchen, etc. For this reason, it is possible to supply hot water at a desired temperature to the second use unit such as a washroom or a kitchen without the need for a mixing faucet, and it is possible to reduce the use of expensive mixed faucets, and to use the second utilization unit. Hot water supply and water supply can be performed without installing a plurality of hot water pipes and water supply pipes, so that piping work can be simplified.

Further, a first use unit such as a bathtub whose hot water supply temperature is set to a high temperature of about 60 ° C. and a second use unit such as a washroom or a kitchen where the hot water supply temperature is set lower than that. Since the arrangement can be eliminated, it is not necessary to go out of the room (for example, a bathroom) where the first usage unit is located in order to set the temperature of the first usage unit. It is easy to use because there is no way to change it elsewhere without your knowledge. Further, since the first temperature sensing member 7 for controlling the valve opening of the proportional valve 8 according to the detected temperature is provided near the hot water supply outlet 1D of the plate heat exchanger 1, the first hot water supply is provided. The hot water supply temperature on the high temperature side (about 60 ° C.) flowing through the pipe 5 can be accurately maintained, and during standby for hot water supply, the proportional valve 8 changes its valve opening in accordance with the detected temperature of the first temperature sensing member 7. Is automatically controlled in a state including the fully closed state, the temperature in the secondary flow path of the plate heat exchanger 1 is maintained at about 60 ° C. Abnormal high-temperature hot water supply due to the boiling phenomenon can be prevented.
