Background
The principle of operation of prior art electric heaters is the thermal effect of the current (a phenomenon that increases the temperature of a conductor when the current passes through the various conductors), which is fundamentally the joule-lenz law. When current passes through the conductor, electric energy is converted into internal energy to heat the heating element, and finally heat is transferred to water to heat water. The electric resistance heater heats water in a container by using heat generated when electric current passes through a conductor having electric resistance.
