ABSTRACT:
A solar air heater comprises a plurality of elongate concentric flexible cylinders which define an outer annular insulating region, an inner cylindrical flow region and a positioning structure therefore. A plastic panel of indeterminate length may be folded upon itself and sealed to form the outer wall of the insulating annulus, the positioning structure and a middle wall. The cylindrical flow region is defined by a self-supporting tube which is inserted into the positioning structure and middle wall. Air flowing through the self-supporting tube is heated by available solar energy and the outer region, inflated by air at a pressure slightly above atmospheric pressure, acts as an insulator.
