PCT No. PCT/DE90/00957 Sec. 371 Date May 12, 1992 Sec. 102(e) Date May 12, 1992 PCT Filed Dec. 12, 1990 PCT Pub. No. WO91/10068 PCT Pub. Date Jul. 11, 1991.A space heater for a motor vehicle contains a burner with a combustion air fan. A series resistor (24) is provided for partial load operation. This resistor (24) is arranged in a housing (2, 6) which surrounds the electric motor (4) driving the fan wheel (14) of the combustion air fan (1) and through which combustion air is passed for cooling the electric motor and the resistor (24). The resistor (24) is soldered to a printed circuit board (20) located radially on the housing, downstream of a combustion air passage opening (22) designed as a cutout in the printed circuit board. The printed circuit board preferably carries a sound-absorbing plate (34) with a cutout (36) in the area of the resistor.
