The Sun Flow solar system operates as a pre-heater. Its function is to raise the temperature of the water going into the existing system. Year-after-year your maintenance-free SunFlow system will go on providing a substantial part of your hot water needs.

• A. Cold water inlet: The cold water line which normally goes directly into the existing water heater is diverted to the cold water inlet on the first Sun Flow collector.
• B. Bottom enclosure: Each collector is nested in an enclosure made of space-age UV stabilized materials for years of durability
• C. Reflective mirror: An aluminized solar mirror with over 90 percent reflectivity and a protective coating to guard against moisture degradation.
• D. Outer glazing: Each collector is covered with a dome made of twin walled GE Lexan®. The Lexan dome is especially designed for passing solar energy while holding in heat. The dome and bottom enclosure combine to form a "greenhouse" effect for additional insulation against windchill factors.
• E. Stainless steel collector/cylinder: Each cylinder is made of 316 L stainless steel and coated with a special, highly efficient, black solar coating to absorb the sun's energy. Each cylinder stores over 25 gallons of water.
• F. Inner glazing: Each collector is enveloped by solar-designed GE Lexan®.
• G. Hot water outlet: The hot water from the collector is then drawn from the top of the first collector to the bottom of the second collector, where it is raised to an even higher temperature. This serpentine plumbing style always results in the hottest available water in the system being drawn into your existing water heater.

The SunFlow's cylindrical tanks combined with the parabolic reflective mirror design captures the sun's full rays at all angles as the sun moves across the sky.

SunFlow is a maintenance-free combination collector and storage solar hot water heating system that has been in use for over seventy years. The SunFLow Integral Collector Storage (ICS) system eliminates the use of any electrical or moving parts, thus producing a trouble-free ICS system. To maintain highest efficiency, you may wish to periodically wash off the accumulated dust on the domes.

ICS units are excellent choices for residential new construction in U.S. Sunbelt or other mild climates that do not experience hard freeze conditions.
