ABSTRACT:
A distribution of solar heat into the ambient air of an enclosed space and a reduction of thermal energy loss from said ambient air and from said enclosed space is provided by means of a box attached to the inner side of a conventional window sash. A vertically-oriented, highly heat absorptive surface within the box has its temperature increased as solar radiation generally in the form of direct sunlight passes through the glass of the window sash, enters the front of the attached box and impinges on the energy absorbing surface. Ambient air from the enclosed space moving by natural convective action enters the box through side and bottom openings in said box, passes over the heated surface in heat exchange relationship thereto, is warmed, leaves the box at or near the top and re-enters the enclosed space at an elevated temperature.
