METHOD AND APPARATUS FOR HEAT CARRIER CIRCULATION FOR A VEHICLE HEATING SYSTEM HAVING A HEATER INDEPENDENT OF THE ENGINE A heat carrier circulation for a vehicle heating system includes a heater independent of the engine. The heat carrier circulation contains a forward line which leads from the internal combustion vehicle drive engine to a heating system heat exchanger for the vehicle interior and which has a parallel branch in which the heater is disposed; and a return line leading from the heating system heat exchanger back to the internal combustion engine. The heat exchanger circulation contains a connecting which goes from the return line to the part of the forward line located ahead of the heater. Installed in the heat carrier circulation is a settable valve which controls the ratio at which heat carrier flows to the heater from the connecting line and from the internal combustion engine.
