Abstract

PURPOSE: To improve the hot water temperature characteristics by controlling a gas valve with the temperature of hot water from an auxiliary heat exchanger having small heat capacity and being installed parallel to a main heat exchanger.
CONSTITUTION: An auxiliary heat exchanger 9 is provided parallel to a main heat exchanger 1, said auxiliary heat exchanger having fins 12 smaller than fins 13 of the main heat exchanger 1 or no fin at all. A temperature detector 8 is provided on the hot water side of said auxiliary heat exchanger 9 whereby a solenoid valve 6 of a gas burner 4 is controlled via a proportional control system 7.
