Working Principle:

a. The high quality vacuum tubes absorb the solar ray to heat the cold water in the vacuum tube.

b. The hot water rises in the top of the manifold case from the vacuum tubes, and the cold water from the manifold case sinks to the vacuum tubes to be heated. So the whole system is always circulating continuously.

Competitive Advantage:

1. All of our solar water heaters are of CE certificate, and our workers are skilled, so that we can ensure the top quality.

2. In our working room, we have a special producing line for this kind of solar water heaters, and the productivity is increased dramatically, so that we can ensure the delivery time.

3. For every order, we provide spare parts, such as vacuum tube, silicon rings, and decoration rings.

4. We have professional team from before sale to after sale. We can produce the products as your requirement, and we can also make a design for you. If there is any problem of installing and using, we can solve it for you very soon.

5. The solar water heaters are easy to install and maintain.

6. We have professional engineers. For solar projects, we can make designs as clients’ requirement, or we can provide the reasonable design to customers.
