Abstract
A heating apparatus, which is intended, particularly, for incorporation into a vehicle liquid heat exchange circuit has a control device, to which a liquid flow measuring device is connected. If the liquid flow measuring device detects that a predetermined liquid flow has been reached or exceeded, the control device of the heating apparatus can be put into operation as a function of other control variables. If, on the other hand, this predetermined liquid flow is not reached or exceeded, the control device, by its connection to the liquid flow measuring device, prevents turning on of the heating apparatus. As a result, the heating apparatus is turned on and delivers heat only if a heating requirement exists.
