Solar project features
Vacuum tube solar collector is comprised of three parts: manifold
case, vacuum tubes (collector), and support (bracket).
- Consists of solar collecting system, water storage system, control
system and pump system High efficient, to make full use of solar
energy can save energy by 80%
- Energy-saving and low cost, intelligent control can save the labor
cost Once invested, benefit for long time
- High safety feature, overheat protection, lightning protection and
- Constant temperature controlling guarantee hot water supply at any

- Changzhou Sunfield Solar is experienced solar water heater leading
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.
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.
