A solar air heater is vertically disposed and composed of a plurality of parallel, horizontally disposed slats resembling a venetian blind. The slats are positioned with their upper faces facing the sun and at an acute angle relative to the horizontal such that the winter sun will produce multiple heat absorbing reflections between adjacent slat surfaces, whereas the summer sun will be reflected back, if desired, so as to impart little or no heat to the heater. Air is circulated through the heater between the slats, thereby becoming heated as it absorbs heat from the slats. This heated air is then sent into a structure, such as a room of a house, via air ducts or the like to heat the structure or is sent to such other areas as desired, the solar air heater being attached to or forming a part of the structure that is to receive the heat produced by its use.
