A dark colored absorbing substrate covered with monolayer of solar radiation, transparent spheres, absorbs solar radiation for heating an air column formed between drapery material and the substrate mounted inside of a transparent window. In one form, a drapery material forms with the substrate a series of tubes for naturally or forcibly circulating warm air through the tubes when the substrate is heated by solar radiation. In another form, a eutectic salt in the tubes stores heat by transending to a higher energy state, so as to subsequently radiate heat on returning to a lower energy state. Reflecting cover means, selectively mountable in front of the substrate, reflects solar radiation back through the transparent window when heating is not required.
