Claim of US Patent No. 10,397,983

1. A water heating element, comprising:a carbon nanotube composite;
a positive electrical connection and a negative electrical connection, wherein the positive electrical connection and the negative electrical connection are configured to connect the carbon nanotube composite to an electric power source; and
a corrosion protective anode, for reducing deterioration of the anode and adapted to extend into the tank of the water heater, comprising a looped electric resistor, a resistor electric insulating layer surrounding said electric resistor, a metallic sheath surrounding said resistor insulating layer, said sheath having an exterior surface of nickel, a sheath electric insulating layer of polytetrafluoroethylene covering said nickel surface and adhering thereto, electric connections to the two ends of the electric resistor, and an insulating support for the electric connections.
