A heating stove including a pair of opposite side walls and front, rear and top and bottom walls interconnecting and extending between front, rear and top and bottom marginal portions of the side walls. A pair of inner side panels are provided and spaced inwardly of the side walls and extend between the top and bottom walls defining interior side wall hollow areas. A rear inner panel is spaced inward of the rear wall and extends between the rear marginal portions of the inner side panels defining an interior rear wall area. A firebox is defined between the side panels and the rear panel and front wall and includes a flue outlet opening outwardly from an upper rear portion of the firebox. Combustion air inlet structure is provided operative to admit combustion air into the lower portion of the interior rear wall area and the upper portion of the interior rear wall area and the rear upper portions of the interior side wall areas are communicated. The lower forward portions of the side panels include openings therethrough into the firebox. Combustion air is admitted into the lower portion of the interior rear wall area, passes upwardly therethrough and into the interior side wall areas and thereafter downwardly and forwardly through the latter and into the forward opposite side lower portions of the firebox. In this manner, the operating temperature of the exterior rear and opposite side walls are greatly reduced.
