HelioMaxxDB Drainback DHW Kit – 80G / SDB (Collectors Not Included)

The HelioMaxx SDB system was designed to bring the simplicity of drainback systems together with some of the better characteristics of pressurized systems to create the easiest installation on the market. Our newly released 3rd Generation System is even more efficient in its design, components and function.

Our StorMaxx SDB Drainback/DHW Tanks are made with extremely durable materials with a high tech titanium steel/porcelain enamel bond that is expected to last 15 years or more. Our spirally augmented copper coils allow extremely efficient heat exchange within the tanks. Our outer jacket made from painted alloy steel provides a very clean look to the system. We use polyurethane insulation for maximum heat preservation.

***We have Flat Plate or Vacuum Heat Pipe Collector models. However, the collectors are not included in the kit, therefore simply contact one of our sales representatives at 1.800.786.0329 for assistance.***
