ABSTRACT:
A thermal heating and heat storage device is provided. The preferred device includes a paraffin based phase change material therein. In addition, the device includes an electrically resistive heating element. The heating element is selectively controllable to heat the paraffin based phase change material to a temperature of at least its phase change temperature. A thermal switch arrangement is provided to control heating. A covering is provided which defines an internal volume in which are positioned the phase change material and the electrically resistive heating element.
