徴とする瞬間湯沸器における温度制御装置。A heat exchanger, a burner that heats the heat exchanger, a fuel proportional valve that varies the amount of fuel supplied to the burner, and outputs a value multiplied by the difference between the set temperature and the water input temperature and the flow rate of the water input, or a value proportional to it. a first control circuit that outputs a value proportional to the difference between the set temperature and the hot water temperature, and a controller that controls the fuel proportional valve according to the combined output of these surface control circuits. In the instantaneous water heater, the instantaneous water heater is characterized in that it is provided with a system number switching means that detects the change in the outlet hot water temperature and changes the proportional operation system of the second control circuit in inverse proportion to the magnitude of this change. Temperature control device.
