Vehicle heating unit comprising an air intake connection and an exhaust connection, which connections are communicable with corresponding inlet and outlet ducts through the vehicle bottom. In order to perform, in such a vehicle heater, the disassembly of the heating unit, even after several years of operation and consequently corroded coupling clamps for the exhaust manifold and the air connection pipe, a coupling unit attachable to the vehicle bottom is provided. The coupling unit comprises plug couplings or contact pressure couplings, equipped with gaskets for receiving the connections, and, associated therewith, coupling pipe sections oriented toward the outside. The exhaust manifold and the air intake manifold can be attached in the usual way to these coupling pipe sections. However, these manifolds need no longer be detached for the dismounting of the heating device. The coupling unit can be mounted within or externally of the vehicle. |
