Heating Tube for Water Heater

The Water Heater Heating Tube is a metal tubular electric heating element specifically designed for electric water heaters. It consists of a metal tube as the outer shell, an alloy resistance wire as the heating element, and high-purity magnesium oxide (MgO) powder as the insulating medium. When current passes through the resistance wire, electrical energy is converted into thermal energy, which is conducted through the MgO powder to the metal tube wall, then heating the water outside the tube.
