Drainback

Drainback systems offer fail-safe freeze protection by removing all water from the collectors and piping when the system is not collecting heat.

Each time the pump shuts off, water in the collectors and exposed piping drains into the insulated reservoir tank.

Drainback systems circulate fluid-transfer solution through the collectors, then through a heat exchanger where the heat is transferred to the potable water in the solar tank.
