Notice in this configuration that only one pump is required to operate the entire system for solar heat collection, space heating distribution, as well as domestic hot water.

Drainback solar boiler | Sunoptimo Solar Thermal

A system based on drainback, also called a self-draining or gravity drain system, allows the solar collectors to drain naturally and passively every time the circulation pump stops. The fluid is thus immune to overheating and freezing. The fluid in the collectors drains back down into the drain tank installed in the boiler room.

Drain-Back-System

Das Besondere am Drain-Back-System ist, dass kein Frostschutzmittel benötigt wird. Dies erhöht nicht nur die Sicherheit der Anlage, sondern verbessert auch deren Effizienz, da Frostschutzmittel wie Glykol die Wärmeübertragungseffizienz der Solarflüssigkeit verringern und somit die Energieausbeute reduzieren.

Why should you choose an active drainback solar thermal system?

Choose an active drainback solar thermal system if you need to protect the heat transfer fluid from outdoor freezing temperatures by draining the fluid into conditioned space. Drainback systems are also common in warm climates because they drainback when the system has met a maximum set temperature in the storage tank.

How does a drainback system work?

In a drainback system, the solar collector is usually mounted on the roof, and the fluid in the collectors is circulated by gravity. When there is no sun, the fluid drains back down into a reservoir tank located below the collectors. This type of system can be used in both residential and commercial applications.
