Method of making a solar heat exchanger
A solar liquid-to-liquid heat exchanger, method of making the same, and hot water heating apparatus employing same are provided wherein such heat exchanger is comprised of a first tubular member made of a heat conductive tube material and having a plurality of turns, a second tubular member made of a heat conductive tube material and having a plurality of turns which correspond to and are fixed against the turns of the first member to provide a strong mechanical and thermal connection between immediately adjacent faces of associated member turns. The fixing of the turns of the members and utilization of the heat exchanger in a hot water heating apparatus with flow of a solar fluid used in such apparatus in one direction through the first tubular member and water to be heated through the second tubular member in counterflow to the one direction assures optimum transfer of heat from the solar fluid to the water to be heated.
