Abstract

A motor vehicle heating device with a burner which has a combustion chamber which is coaxially surrounded, at least in part, by a heat exchanger which has a closed end at an end of the combustion chamber opposite that at which the burner is located, and which has an annular space, which is defined between an outer wall and inner wall, through which a liquid heat transfer agent flows. The heat exchanger is made of a one-piece construction, so that the end of the heat exchanger joins its outer and inner walls, and at the same time, its inside faces the combustion chamber. By this construction, the liquid-carrying part is essentially formed by a single part, so that no integrity problems can occur between the liquid-carrying annular space and the exhaust gas-carrying interior of the heating device and production costs are reduced.
