Abstract: A solar-powered fluid heating system, having a thermal collector, a unitary water conducting assembly, and heat retention and efficiency components that are all included in a framework so as to provide a unitary construction. The framework includes a frame structure having non-conductive receptacles for receiving the edge marginal regions of the thermal conductor, so as to be free-floating to allow for thermal expansion and reduction of stresses on components as well as the heat resistant and enhancing components. The arrangement within the frame structure includes a dimpled or waffled metal water conducting assembly that rests upon a layer of insulation material held in the framing structure by a back sheet. The opposite side of the water conducting component is a solar selective sheet having a blackened surface upon which a thermal collector is disposed.
