ABSTRACT:
A system and a method of operating that system are used to quickly adjust the temperature of an electric stove heating element. A heat transfer or moderating fluid is pumped through a hollow portion of an electric stove heating element. The moderating fluid is heated or cooled to an appropriate temperature, and inserted under the control of a microprocessor to more quickly modify the temperature of the stove heating element. The system allows rapid temperature changes in normally sluggish electric stove heating elements. Also, accurate temperature adjustment is permitted by the microprocessor controlled.
