PURPOSE:To individually heat rooms by performing the heating with a main heater to which hot air is supplied which is heated by the secondary heat of a heat exchanger casing heated by a burner, and with an auxiliary heater to which hot water stored in the heat exchanger casing is circulated. CONSTITUTION:The heat exchanger casing 13 is heated by the turning of a burner 11, and, because of such heating, water stored in the heat exchanger casing 13 is heated and the heat exchanger casing itself becomes hot as well. The secondary heat radiation from the hot heat exchanger casing 13 is converted to hot air which is supplied to the room through a main space heater 10. Further, hot water stored in the heat exchanger casing 13 is circulated to an auxiliary space heater 20 which radiates heat to warm the room. Therefore, the main heater 10 and the auxiliary heater 20 can be independently adjusted for heating by respectively regulating the usage rate of heat retained by the heat exchanger casing 13 between them, and so, the heating adjustment can be made for individual rooms.
