Abstract
Abstract A self-contained automatic heater unit for a vehicle such as a truck trailer or the like in which a temperature sensor automatically ignites a pre-heater by means including a rechargeable power source to supply a mixture of hot air and fuel to a burner plate of large area the burners of which are ignited when the pre-heated mixture reaches a certain temperature and the products of combustion of which are first brought into contact with the hot junctions of a thermopile and then are passed through a heat exchanger to which air from the space to be heated is supplied by a fan which first moves this cool air past the cold junctions of the thermopile and then through the heat exchanger to the space to be heated and in which the voltage produced by the thermopile recharges the battery which provides a power source for the system.
