Heat Exchangers for Solar Water Heating Systems ...

Solar water heating systems use three types of heat exchangers Liquid-to-liquid A liquid-to-liquid heat exchanger uses a heat-transfer fluid that circulates through the solar collector, absorbs heat, and then flows through a heat exchanger to transfer its heat to water in a storage tank. Heat-transfer fluids, such as antifreeze, protect the solar collector from freezing in cold weather.
