ABSTRACT:
There is disclosed an electric heating unit having a housing with air circulation apertures, a heating element, and a passive heat storage member adjacent the heating element. The heat storage member is preferably a sealed chamber containing a heat storage material such as silica or oil. Heat transfer fins surround both the heating element and the heat storage member to facilitate heat transfer to the atmosphere. The heat transfer fins engage the heating element and the heat storage member with gripping collars which may be loosely fitted for installation, and a portion of the collars frictionally engaged with the respective element and storage member to secure the fins into an aligned position. The heat storage member continues to disburse heat to the surrounding atmosphere while the heating element is de-energized, thereby providing a uniform heating source to the room such that fewer energizing and de-energizing cycles of the heating element are required.
