To develop hot water generating system using solar energy. The collectors, black crome plating and carbonblack have been applied in cheaper and simpler processes, and sillicon oil has coated for the double glass effect as well as the absorption of radiant heat. The wood, processed with special chemicals, not Aluminum, has been used for the cases of collectors without any welding between copper plates and copper pipes. The thermal energy storages, cheap polyethyllene tank of over 3 drum volume, have been used instead of the current expensive thermal energy storages, and heat carriers have been circulated forcefully by both check values and low power pumps. Na₂SO₄·10H₂O has been packed with special plastic materials and put into the thermal energy storages, which has brought about the thermal energy storage effect.
