ABSTRACT:
A heating device fed with free-flowing fuel and connected to an on-board voltage source, in particular, a vehicle heater. The heating device is equipped with a burner assembly which has a fuel supply, a combustion air fan and a heating element which ignites a fuel/air mixture after a preheating phase. During the preheating phase, the combustion fuel fan is shut off or at least is operated at less than the operating blower output. There is also a switching device which automatically turns on or switches the combustion air fan to its operating blower output after a preheating phase has been completed. The switching device is designed as a voltage-dependent time-function element, which presets a preheating time dependent upon the magnitude of the on-board voltage and which decreases the preheating time as the on-board voltage increases.
