PROBLEM TO BE SOLVED: To accurately detect room temperature using a room-temperature thermistor and make the hot air circulate about a room ceiling part, even when combustion stoppage in heating operation. SOLUTION: A second blower is disposed inside a second air inlet 3 above the room-temperature thermistor 18, and the discharge opening of the second blower is positioned so as to be provided in the top panel part of the body case 1. The second blower 19 is rotated, when a first blower 11 is stopped when combustion is stopped. Room air is continuously circulated inside the room temperature thermistor 18 and enables accurate room temperature reading. The discharge of the second blower 19, which is directed to the room ceiling, can circulate warm air that is stagnant about the ceiling to eliminate burner combustion unnecessarily and energy saving can be expected.
