ABSTRACT:
A heating and ventilating apparatus for a motor vehicle having either an internal combustion engine or an electric propulsion motor, where the heat given off by the engine or motor is insufficient to provide heating requirements for the cabin of the vehicle under all conditions, comprises an air inlet chamber associated with a blower, and an air outlet chamber which feeds at least one outlet duct, leading to the cabin. A heating branch is interposed between the inlet chamber and the outlet chamber, with heating means arranged in the air heating branch. The heating means comprise a radiant heater having pure or passive resistance, together with a radiant electric heater having a positive temperature co-efficient resistance, the two heaters being connected electrically in series in a circuit which is supplied by a voltage source.
