flexible assembly,combined with building in perfect.solar collector composed of vacuum tubes,which is good in pressure bearing,high efficiency and sanitation. Tank can bear 2Mpa pressure.All the system with close circulation desgin.
And with electric back up inside for no enough sun shine.Even if in cloudy or raining day,you can enjoy hot water.　
Separate pressurized solar water heater takes advantage of high absorptance and low emittance of vacuum tubes and converts absorbed radiation into heat energy and sends it rapidly to collector by heat pipe conductor.It can work efficiently in four seasons.

　　 Pressurized Tank
With 3 layers, stronger in bearing pressure
Inner tank adopts imported porcelain enamel material. It composes of three layers. That's non-metal inner layer, mixed layer and alloy steel layer. It's good in intension, high pressure resistance, corrosion resistance and heat and cold compact resistance.
Non-metal inner layer is with smooth surface. Non-metal film was coated on inner layer and integrated with inner layer after baking under 870 degree high temperature. It can be expanded with inner layer together freely and with big magnesium rod inside for protecting tank free of scale.
In complying with American pressure bearing standard 2MPa. ,which is 67% higher compared with our domestic standard. It's also with UL approval and with long life in 100,000 times. Each inner tank has to be tested under 21KG/CM2.
