摘要： An independent leg heater is disposed in a heat storage material to melt some of the material and provide an escape channel for the bulk of said material as it liquifies. Special heater circuitry provides for the regulation of heating periods for the independent leg heater (1) to apply heat automatically prior to activation of the main heating elements, (2) to stop the application of heat when the heat storage material is molten to prevent overheating in the upper region of the storage material surrounding the leg heater (3) to shut down the entire system if the leg heater fails to operate.
