If you saw us in Home Power Magazine this month, chances are you're wanting to know a bit more about our brutally honest comparison of a glycol or 2 tank drainback and our Simple Drainback™ System.

Compare Glycol or a 2 Tank Drainback vs. The Simple Drainback™ System:

Aside from low cost and easy installation due to design simplicity, the U.S. designed and patented Simple Drainback system enjoys substantial operational advantages over other freeze protected systems, including enhanced tank stratification and heat exchanger performance.

SHEM’s load-side immersed coil heat exchanger maintains and enhances tank stratification, allowing collectors to operate at dramatically higher efficiencies. Spirally augmenting the massive copper heat exchange coil creates an internal boundary-layer interruption that increases heat transfer without increasing flow velocities, resulting in 30% increased heat exchange over smooth wall copper.

Tank life is enhanced because a single charge of collector loop water resides in the storage tank, relieving the tank from the constant attack of calcification, sedimentation and oxidation.
