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.

[ We claim:] [1.] An electrical heating unit for warming atmosphere adjacent the unit comprising:a housing having an interior space in fluid communication with the surrounding atmosphere;a heating assembly positioned within the interior of said housing, the heating assembly comprising an electric heating element having an electrical current source selectively energized and de-energized by a means for controlling current and having an outer heat emitting surface; and,a heat storage member having a chamber with an outer surface adjacent the electric heating element, the outer surface of the heat storage member being positioned relative the heat emitting surface to receive heat transferred from the heating element when said element is energized and adapted to heat the content material of said member to heat said member, and said heat storage member being adapted to continue to disburse heat to the adjacent atmosphere subsequent to the electric heating element being de-energized as said content material cools, said content material being adapted to heat and cool without phase transition of its physical state.
