IMMERSION TYPE HEATING ELEMENT WITH A PLASTIC HEAD FOR A STORAGE WATER HEATER TANK

摘要

An improved electric immersion heater wherein the metallic heating element sheath is mechanically and electrically secured to a dielectric element head rendered conductive by suspending carbon or metallic conductors in the dielectric to produce a predetermined resistance. This allows anodic current to flow from the heating element sheath to ground when the conductor is installed in a water tank without the need for external resistors or tinning of the heating element sheath.
