Claims

[Scope of utility model registration request]

A pump is installed in a loop-shaped water heater in which a heat exchanger and a temperature sensor are installed in the outgoing path of the water passage, and a pressure sensor, a three-way valve, and a check valve are installed in the incoming path, and a pump is installed in the water heater in the outgoing path. A bypass path is provided that branches off from the middle of the water heater and communicates with the three-way valve disposed on the return path, and an outbound header and a return header are installed at the outbound outlet and return inlet of the water heater, and from each header Relatively small-diameter outgoing and return pipes are covered with a heat insulating material and integrated into hot water supply piping, and when hot water is not needed, the three-way valve is switched to close off the bypass path, and at the same time, the pump is driven to maintain the appropriate temperature at any time. A domestic hot water supply device, characterized in that hot water is circulated so that hot water can be supplied, while when hot water is being supplied, the three-way valve is switched to open the bypass passage, and hot water is supplied from both the outgoing pipe and the return pipe.
