ABSTRACT:
A double loop heat storage space heating furnace has a housing with an upper heat storage section containing an electrically heated heat storage brick portion and a lower section containing an air-to-air heat exchanger having first and second air flow passages. The furnace has two separate flow courses. The first flow course uses a room air fan to circulate room air through the first passages of the heat exchanger. The second flow course has a recirculating fan in the lower housing section for recirculating air in a continuous closed loop through the heat storage brick portion to be heated and the second flow passages of the heat exchanger so that heat is delivered from the heated recirculated air and the room air in the heat exchanger. The upper housing section includes a cooling air space surrounding the heat storage brick portion through which the room air fan circulates a portion of the room air to maintain the furnace housing at a temperature similar to that of the room air.
