Closed Loop Thermosyphon Solar Water Heater

Active closed loop systems use electric pumps valves and controllers to circulate the heat transfer fluid usually a polypropylene non toxic unlike polyethylene glycol water antifreeze mixture through the collectors.

Closed loop thermosyphon solar water heater.

Closed loop solar water heaters. Inside the heat exchanger is a glycol formula that prevents freezing of the potable water. Closed loop systems use a heat transfer fluid to collect heat and a heat exchanger to transfer the heat to household water. Closed loop solar water heater systems sometimes referred to as anti freeze or glycol systems include the heat collectors insulated piping a circulating pump an expansion tank a hot water storage tank a heat exchanger solar fluid usually a solution of water and nontoxic propylene glycol antifreeze a controller valves and gauges.

There is an external heat exchanger in the tank. Closed circuit system if the heating fluid is the antifreeze solution we are talking about the closed circuit thermosyphon solar water heater and they can be used in the areas that are prone to frost and have hard water issues. Rheem solar thermosyphon storage tank has an exterior casing made from anodized aluminum which is extremely durable to ultra violet rays in humid climates and in coastal areas. Heat is transferred to the potable water through the heat exchanger in the lower portion of the storage tank.

When mounted on the roof the house is provided with gravity fed hot water. Wombat vented thermosiphon solar water heaters are a great choice for consumers who want a cost effective hot water solution.
