Features and advantages

1, High efficient and economical system.

2, The water inside of the vacuum tubes

3, The vacuum tube insert into the non-pressure tank , so the hot water and cold could circulate by

themselves beacuse of the different density.

4, Reliable and efficient with twin-glass solar tubes

5, Polyurethane insulation ensures a good heating performance and loss.

6, Easy to install and high heat transfer rate over 95%


This system relies on natural circulation, the water in vacuum tube will be hot after the coating layer absorbs

solar energy . As we know, hot water is lighter and the cold water is heavier, so hotter water will flow into

tank and colder water will flow to vacuum tube bottom. This circulation continues because of different water

temperature between the tank and vacuum tube.  At last , the water temperature in the tank and vacuum tube

will be the same ,and circulation will stop. then you can get hot water after several hours.
