Abstract
A method for heating diesel prior to filtration by passing the diesel fuel through a heating apparatus including a container having entry and exit ports for the fuel and an elongated electrical heater arranged in spaced apart coils within the container for directing the flow of fuel so that, as the fuel flows from the entry port to the exit port, it flows along an elongate curved path which follows the coils of the heater and which curved path preferably has a length at least eight times the straightline distance between the entry and exit ports. The electric heater is unjacketed and comprises a pair of elongate electrodes embedded in an elongate strip of a conductive polymer composition which exhibits PTC behavior. The exterior surface of the elongate polymer strip is exposed so that it is directly contacted by the diesel fuel flowing through the container.
