Closed Loop Solar Hot Water Heating

Closed-Loop Active Systems pump heat-transfer fluids such as glycol-water antifreeze through the solar water heater to a heat exchanger.  Another Heat exchanger transfers the heat from the transfer-fluid to the potable water.

Closed-loop glycol systems are popular in areas subject to extended subzero temperatures because they offer protection against freezing. Glycol-water based systems have a poorer heat transfer co-efficient than of water to water. Glycol-water based systems, like your car's antifreeze the systems must be checked periodically and the glycol must be replaced when it comes to end-of life.
