A self-powered space heater. At least one thermoelectric module is sandwiched between a hot surface of a combustion chamber of a fluid fired space heater and a room air-cooled heat exchanger for transferring heat from the space heater to room air. A blower circulates room air through the heat exchanger for the dual purpose of heating the room air and also removing heat from the heat exchanger. In a preferred embodiment two thermoelectric modules are utilized in a diesel fuel fired space heater to provide heated air for the cab of a diesel truck. Spherical self-alignment washers are used in a compression frame to apply uniform compression force to both hot and cold sides of the thermoelectric modules. The two modules provide about 25 Watts output that is more than sufficient power to operate the heater that requires about 20 Watts. Extra power can be used for other purposes such as battery charging. The invention is also useful to provide self-power to heaters in vehicles other than truck and other space heaters such as pellet stoves and fireplaces.
