Claims

[Scope of utility model registration request]

A heat exchanger heats supplied water with a burner to supply hot water, a control valve controls the amount of gas to the burner, and a control valve is installed on the water supply side and the hot water supply side of the heat exchanger to ensure the linearity of resistance change with respect to temperature. The sum temperature of the inlet water temperature and the outlet water temperature of the heat exchanger is kept approximately constant with respect to the set reference temperature by the detection signals from the first and second temperature detection elements. and a control section that controls the control valve.
