Characteristic of this type
All-glass evacuated tube adopts vacuum insulation, and the thermal preservation of water tank is foaming of polyurethane at high pressure. Our products are configured with energy saving standard, which solves the heat loss caused by the heat transfer, heat conductivity and heat radiation.
this type of solar water heater works with high pressure, so do the water it produces
The water tank and the solar collector are apart ,it is easy to install.
it uses the heat pipe to delivery the heat energy, it can work more rapidly than others
There is no water in the vacuum tube , so the tube will not break in the winter.
It is steady and credible.
The assemble angle has a great influence on the performance of this type
It will be affected by the local water quality,it does not suit hard water.
It can be combined with the architecture prefectly
It can be combined with existing pipeline.
It can still operate in the event of occasional tube breakages
