    • The vehicle heater described has a burner supplied from a tank through a fuel line to which a pressure-controlled fuel pump (2) and a solenoid valve (24) are connected. The solenoid valve offers a relatively high resistance to the flow of fuel. The pressure in the pump delivery line thus drops relatively slowly. If vapor/gas forms in the fuel line (L2, L3, L4) due to overheating, it must be driven out of the line as rapidly as possible when the heater is switched on. The solenoid valve (24) offers only a low resistance to air/vapor/gas, resulting in a rapid drop in pressure at the pump delivery outlet and hence an increase in pump frequency (i.e. pump performance). The gas is therefore driven very rapidly out of the line between the pump and the burner, thus avoiding any interruptions in operations due to gas/vapor which has collected in the fuel line.

    • 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).
