The Unique Solar Hot Water Drainback System.

Solar Drainback Collector

Drainback Principal

This unique Solar Hot Water System is known as a Drainback System, provides for the automatic emptying of the Collector or Solar Panel and piping whenever the system is turned off or whenever the collector temperature strays outside a specified temperature range. The circulation pump shuts itself down and then the water drains by gravity to the storage tank and Heat Exchanger. By means of such Drainback system the overheating or freezing of a Solar heating System can be avoided. Furthermore, the use of chemicals like glycol as anti-freeze is not necessary.
