PROBLEM TO BE SOLVED: To improve comfortableness in combined heating of a floor heating panel and a room heater. SOLUTION: A circulation pump 11 in a hot water circuit 10 is driven to determine a target temperature of hot water flowing out of a heat exchanger 12 for heating based on a difference between a set temperature with a remote control 4 and a room temperature with a room temperature thermister 403 for controlling the combustion of a gas burner 100. The hot water heated with the heat exchanger 12 by combustion with the gas burner 100 is supplied simultaneously to a heat exchanger 15 for heating and a floor heating panel 3 of a room unit 2 to actuate a convection fan 200. When the room temperature becomes higher than the set temperature, the convection fan 200 alone is stopped and the target temperature of hot water is determined based on the temperature of the outside air detected by an outside air thermister 404 to control the combustion with the gas burner 100. When the room temperature becomes sufficiently high, no excessive heating is done and hence, no insufficient heating is caused.
