Drainback Systems are one of the most common system designs for solar hot water, since they provide very simple operation and adequate freeze protection for most climates. Unlike pressurized glycol system designs, drainback systems can utilize potable water directly in the solar collector loop. This means that your system can be installed as an open loop or a closed loop system, providing even greater design flexibility. This flexibility, as well as low pricing, make drainback solar hot water systems one of the most popular forms of Solar Hot Water Systems installed around the world.
