Characteristic

1,There are double inner tanks.
2,It takes the advantage of the tap water's pressure.
3,Completely automatic operation.
4,The water can be heated rapidly.
5,Use the non-pressurized inner tank as the heat exchanger, simple to install and use.
6,Directly connected with city water without a circulation pump.
7,Working pressure(0.6MPa)

Working Principle

the vacuum tube absorbs the sunlight and turns it into the heat energy, heating the water in the tubes. Depending on the thermosiphon principle, the hot water from the tubes goes into water tank, while the cold water from the tank goes down to the tubes.
there are double inner tanks, first inner tank is non pressurized, the second inner tank is pressurized.
user do not use the water from the non-pressurized tank directly. the cold water goes into the pressurized inner tank, be heated, then come out from other side for user being.
