Drain-Back Systems protect against freeze damage by draining the collectors when they're not producing hot water. The collector(s) has to be slightly tilted to allow drainage. They also have to be higher than the drain-back tank. Ground-mount collector configurations are sometimes not possible.

SunQest builds heat exchangers for drainback tanks.  Our Ultrasonic Welder provides a permanent, efficient bond between the copper fin and the flow tube.  Parallel "Fintubes" are brazed into common headers providing low-loss, high area exchange.
