PCT No. PCT/EP94/04309 Sec. 371 Date Jun. 3, 1996 Sec. 102(e) Date Jun. 3, 1996 PCT Filed Dec. 27, 1994 PCT Pub. No. WO95/18342 PCT Pub. Date Jul. 6, 1995An engine-independent vehicle heating appliance has a combustion air fan, a fuel dosing pump and a heat exchanger that surrounds the combustion chamber, as well as a controller that controls the operation of the vehicle heating appliance. In compact designs, special measures are required to protect the electronic components of the controller from overheating. In order to carry off heat in an effective manner, the controller has a heat conducting plate upon which the electronic power components (18) are mounted, their connections being electrically connected to the wiring on the board (16). Loss heat that results from the operation of the components (18) is carried away by the material of the heat conducting plate (8a, 8b) to the fan housing (6). Since the latter is always cool a sufficient cooling of the components (18) is ensured.
