Apparatus employing a container of compressed fuel such as propane for warming an automobile prior to the occupant's use thereof, particularly on extremely cold days. This device employs a timer that is set to actuate the energization of a glow plug and air valve which allows the fuel to enter the heat exchanger in which the fuel is burned. The timer controls the device so that the glow plug and air valve are turned off after a predetermined time of operation. The timer may also be set to keep the heating cycle on until the occupant of the vehicle turns it off.
