SunEarth DrainPack Hot Water Station – 80 / 120 Gallon Solar Drainback System
The SunEarth DrainPack Hot Water Station is a factory-assembled solar thermal hot water system engineered to simplify the installation of drainback solar water heating systems. Designed for seamless integration with SunEarth's Cascade drainback collector systems, the DrainPack HWS arrives pre-plumbed and hydraulically tested, reducing installation time while improving long-term reliability.
The system combines a glass-lined storage tank, an integrated 6-gallon all-copper drainback reservoir, stainless steel circulator pump, differential temperature controller, mixing valve, expansion tank, and service bypass valves into one professionally assembled package. During normal operation, water drains safely back into the reservoir whenever the pump stops, providing reliable freeze protection without relying on glycol.
Ideal for residential applications in cold climates, the DrainPack HWS offers dependable domestic hot water production while maximizing solar energy efficiency through a durable, low-maintenance drainback design.
