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, is provided with a combustion control circuit. The control circuit acts to maintain a predetermined air-to-fuel ratio at a constant value in the combustion chamber of the heater ("lambda value") by energizing the controllable fuel feed pump and/or the controllable combustion air fan.
