ABSTRACT:
Apparatus for heating the fuel oil exiting from an oil supply tank and in the supply pipe leading to an oil burner furnace. The return oil line, from the pressure relief valve in the oil burner unit, is led to a coil fitted about the furnace stack leading from the oil burner furnace. The outlet of this heating coil is then led into a metal tempering box, mounted below the tank, through a pipe banded to the supply pipe so as to warm the oil in the supply pipe and the oil in the tempering box. Supply oil is fed from the oil supply tank into the tempering box, to mix with the heated oil in the tempering box, with the mixed warmed oil led from the tempering box into the supply pipe leading to the oil burner of the furnace.
