The heater of an electric water heater is usually composed of a set of electric heating tubes, which are made of a metal material that can withstand high temperatures, such as stainless steel or copper. These electric heating tubes are installed inside the water heater, converting electrical energy into thermal energy through resistance, thereby heating the water. The power of the heater can usually be set at the factory or selected by the user according to their own needs when purchasing.

Electric heater is an internationally popular electric heating device. Used for heating, insulation, and heating of flowing liquid and gaseous media. When the heating medium passes through the heating chamber of the electric heater under pressure, the huge heat generated during the operation of the electric heating element is uniformly carried away using the principle of fluid thermodynamics, so that the temperature of the heated medium meets the user's process requirements.
