Abstract
PURPOSE:To improve a hot water outflow characteristic, by opening or closing a fuel valve of a burner in relation to each of plural thermo-circuits whose set temperature is different, and increasing or decreasing gradually the quantity of supply of fuel to the burner in accordance with a temperature of hot water. CONSTITUTION:This device is provided with plural thermo-circuits which are operated by a set hot water temperature, and are different in a set temperature, and fuel valves 13, 15 of a burner 10 are opened or closed in relation to said each thermo-circuit, so that the quantity of supply of fuel to the burner 10 can be increased or decreased gradually in accordance with a variation of a hot water temperature. For instance, 2 thermo-circuits for comparing a detected temperature by a temperature detector 9 such as a thermistor, etc. provided in a water chamber 1, with a set temperature are provided, and by their outputs, the first electromagnetic valve 13 of one gas passage provided with an orifice 14 in the lower flow of a branch gas passage extending to the burner 10, and the second electromagnetic valve 15 of the other gas passage are opened or closed in accordance with a hot water temperature, respectively.
