Abstract
Abstract For use in a solar heating system in which is employed a source of a heatable fluid, a solar heating panel made of spaced corrugated metal sheets which form an envelope which is fed by tubes attached to the top and which is drained by tubes at the base. The envelope may alternatively be made up of flattened tubes which would compartmentalize the envelope. The envelope is coated with Teflon to improve heat retention and reduce heat loss.
