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 copper coil as the heat exchange collector loop.  The pressurized solar water tanks could be placed in series with the existing hot water heater that uses electric, gas, oil, or wood to heat water (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  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.

These are solar water heater storage tank, with total 6 in/outlets: 2 for circulating with collector loop, 1 cold water in, 1 hot water out, that 4 in/outlets are on the side of the tank; 1 for T/P valve install that is on the top of the tank, 1 for drain valve install, that is at the bottom side of the tank.
