ABSTRACT:
Vehicle heater with a tubular combustion chamber and with a pot-shaped heat exchanger crimped over the combustion chamber leaving an annular space, said heat exchanger deflecting the combustion gases in an axial direction. In order to improve the efficiency of such a vehicle heater and to keep the manufacturing and material costs as low as possible, a coaxial, double-walled pot is provided in such a vehicle heater, leaving an annular space between it and the heat exchanger, said pot having an opening in its bottom area and being connected at that point to the annular space between the combustion chamber and the heat exchanger in such fashion that the combustion gases are guided in the chamber between its inside wall and its outside wall and are from there conducted away by an exhaust pipe.
