Household solar heat exchange method selection

Solar water heating: How it works & benefits explained

Heat exchanger: This device facilitates heat transfer from the solar-collected fluid (often a specialized heat-transfer fluid) to your home''s water supply without mixing the two fluids. Heat transfer fluid : This is a specialized liquid used to absorb and transfer heat from the sun to the domestic water supply, typically through a heat exchanger.
