Solar heat storage
Solar energy is the energy different from the regular fuel or gas, it is a day-time accumulated energy and
needs to be stored for constant usage.

Pressurized Solar Water Storage Tank
SEA pressurized solar hot water storage tanks are very efficient in terms of energy saving and storage,
as well as their long life time. Each tank is made of thick coated galvanized steel exterior and patent
porcelain enamel coating liner (Golden Dark-Blue Diamond Coating). Each tank is insulated with high
density polyurethane for maximum heat retention. Also available are heat exchanger collector loop for
potable water. The pressurized solar water tanks could be placed in series with the existing hot water
heater that uses electric, gas, oil, or wood, (which now could be used as a backup heating system
providing extra hot water storage capacity). When the water temperature is up to 140°F, the existing
water heater remains off.
Golden Dark-Blue Diamond Coating, Ultimate protection
At the heart of almost every water heater is a steel tank. A porcelain enamel coating protects the tank
against the corrosive effects of hot water. The technology breakthrough Golden Dark-Blue Diamond
coating formula is enriched with a higher level of zircon, producing a lining that is harder and more
water-resistant than others in the industry.
The superior water resistance of Golden Dark-Blue Diamond Coating has been demonstrated in
accelerated tests against glass lining samples taken from competitive water heaters.
These tests determined water resistance by measuring the rate at which each glass lining sample
dissolved over the 30-week test cycle. The results (expressed in milligrams [mg] of weight loss per
square inch of lining surface) are an indicator of how the glass lining will stand up to constant exposure
to hot water. The lowest mg/sq. in loss shows that Golden Dark-Blue Coating outlasts the best.
