Propylene Glycol is used in indirect solar hot water systems with a heat exchanger in the solar storage tank. The heat exchanger is filled with closed circuit fluid "Propylene Glycol & Water" and is connected to the solar collectors forming a closed circuit. The closed circuit fluid is a solution of a non-toxic food grade propylene glycol concentrate mixed with water. The closed-circuit concentrate is used to lower the freezing temperature of the closed circuit fluid and provides protection against freezing.
For areas which experience frost or snow, or have less-than-reliable water quality, the a closed circuit system is the best choice. It uses the highly-efficient heat transferring properties of a special anti-freeze fluid, Glycol to transfer the absorbed energy to heat the water indirectly. With this system, the water does not pass through the solar collectors, instead a Glycol mixture is circulated from the solar collectors through a jacket which is wrapped around the storage tank, or via a heat exchanger coil in the tank, transferring heat into the water "indirectly".
The benefit of this indirect heat exchange process is that the system can be used confidently in frost areas, without risking damage to the system; it offers protection against freeze damage in conditions of up to minus 18 degrees Celsius depending on the final concentration of the fluid.
