Heat Exchangers for Solar Water Heating Systems
Solar water heating systems use heat exchangers to transfer solar energy absorbed in solar collectors to potable (drinkable) water. Heat exchangers can be made of steel, copper, bronze, stainless steel, aluminum, or cast iron. Solar heating systems usually use copper, because it is a good thermal conductor and has greater resistance to corrosion.
