Abstract
A portable space heater having a deep fuel tank in conjunction with a fuel pump for raising the fuel to a predetermined height to feed an aspirating type nozzle incorporated in the fuel system and an adjusting valve means to control the flow of fuel to the siphon line connected to the nozzle. The fuel pump feeds the fuel from the tank to a predetermined level at which the aspirating nozzle will operate efficiently. The fuel line system also has a return line to the tank which allows any excess fuel in the lines to be appropriately returned to the tank.
