ABSTRACT:
A fuel-operated heater, especially an auxiliary heater for a motor vehicle, with a fuel feed pump and/or with a combustion air fan, the heater, being operated in a predetermined lambda range. The heater is associated with a pressure sensor, by which the controllable fuel feed pump and/or the controllable combustion air fan can be energized via a control device. The pressure sensor may be arranged externally or also in the heater, especially on the pressure side of the fan. Not only changes in air pressure caused by atmospheric conditions, but also system-dependent changes in air pressure can be corrected in the case of the arrangement of a sensor on the pressure side of the fan.
