摘要

b improved method to heat the water in the water tank of an initial cold temperature until a selected temperature.And water heater d a water heater having a water tank and a heating element of electric resistance (125) extending into the water tank to heat the water in the TanquE. the water heater comprises a temperature controller of the proportional (100) to conduct electric power to the heating element of the electric resistance (125) increases.Each increase of electric energy is followed by a period during which the temperature controller does not conduct electricity to the heating element of the electric resistance (125).In one form,Each increase of electric energy is approximately 95% or less of a cycle from an increase of electric power followed by the period of time during which the temperature controller (100).The driving electric power.
