Working Theory:
Since the density of hotter water is much small than colder water, the hotter water is always floats upon colder water.
The coat of vacuum tube absorbs solar irradiation to warm water inside tube, hotter water rises from tubes to storage tank, and the same time colder water in storage tank sinks down to vacuum tubes, this natural convection will last till the water in whole system reaches the highest temperature due to local solar irradiation and duration in a single day.

Optional Device:
Assistant tank, a device installed on top of storage tank, with a float ball valve inside to control water refill for storage tank automatically.

Electrical heater, an electricity based heating device installed in storage tank to assist solar water heating in cloudy or rainy days.

Intelligent controller, a device with sensor and valve for automatic water refill and temperature display, if necessary control electric heater.

Anode magnesium: A device installed in hot storage tank to effectively prevent solar system from generating water scale.

Applications:
Domestic hot water for shower, washing
 
Competitive Advantage:
1.Adopts the best conduction performance metal- heat pipe (copper)
2.Can be used all year round in the cold climate
3.High efficiency, rapid warming. Heat pipe in vacuum tube could transfer hot energy to cold water in pressurized solar water heater tank rapidly
4.The whole pressure of the system is up to 1.5kg/M2, the inlet could connect the tap water directly, the max pressure can be 0.6Mpa
