Abstract: A fuel-operated air heater (1) is disclosed, especially an air heater for automobiles that is operated independent from the motor. The inventive heater comprises a burner (2), a combustion chamber (3) and a heat exchanger (4). Hot air (5) is circulated through the combustion chamber (3) in a cup-shaped heat exchanger having a bottom that is closed on the inlet side and a hot air blower (10). The heat exchanger is also fitted with an overheat sensor (8) and a flame sensor (9) to monitor or detect overheating of the air heater during operation and the formation of flames during starting by means of a control device (6) and optionally to limit overheating or to disconnect the air heater. The overheat sensor (8) is mounted as a hot air temperature sensor in the area adjacent to the blower in the heat exchanger (4), especially with no wall contact in the hot air flow (5).
