Servamatic Solar Hot Water

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.
