Claims

[Scope of utility model registration request]

A detection signal from a thermistor 5 installed on the outlet side of the heat exchanger 2 to detect the hot water temperature is applied to the proportional control valve 4 of the burner 1 via a controller 6 to control the input amount. A flame sensor 3 is installed in a water heater that is regulated for a certain period of time and then proportionally controlled. After the maximum combustion output, the flame sensor 3 detects the flame and controls the initial input amount for a certain period of time, and then performs proportional control. Characteristic water heater.
