Abstract
A motor vehicle with a passenger compartment heating system that allows the interior of the compartment to be heated in substantially noiseless fashion, without a disturbing draft and with a reduction of power consumption. The heating system includes a heat exchanger connectable to the engine cooling circuit and a heater that is operable independent of the engine and a separately disposed heating element that is traversable by a liquid heat conductor. The separately disposed heating element is alternately connectable with the engine cooling circuit, the independently operable heater, and both the cooling circuit and independently operable heater.
