ABSTRACT:
An electric thermal storage heating unit including (i) an insulated housing defining a storage chamber with two laterally extending linear openings through the base of the storage chamber, (ii) a plurality of heat-sink bricks within the storage chamber which define separate vertical ducts above each of the lateral linear openings, and (iii) a pair of substantially planar, serpentine electrical heating elements each defining an uppermost portion with parallel upper right and upper left sides and a lowermost portion with parallel lower right and lower left sides wherein the uppermost portion is angled with respect to the lowermost portion within the plane defined by the element so as to cause the right and left sides of the lowermost portion to extend at an obtuse angle of less than 180.degree. with respect to the corresponding right and left sides of the uppermost portion and thereby facilitate insertion and removal of the heating elements through the linear opening and into the vertical ducts with minimal clearance.
