Working principle

The design of this type uses the all-glass evacuated solar collector tubes as the heat-absorb element. The high vacuum degree of the clearance between the outer and inner tube can reduce the heat emission which caused by convection and conduction to a very low level. All-glass evacuated tube transfers sun energy into heat energy by the high absorption rate and low emittance rate of layer films. Depend on the different density between the hot water and the cold water, a cycle can be created in the tube which hot water ascending and cold water descending status. Keeping natural circulation like this, the water in the tank will be heated.

Advantages:

1. Can he operated completely automatic if connect with intelligent controller.

2. Simple structure, easy plug-in installation, can be installed both on flat and inclined roof, and can be used with an auxiliary electric booster as to provide hot water without sunshine.

3. Superior heat preservation ensured by one-off molding polyurethane foam with thickness

50~ 65mm .

4. Suitable for camping area, holiday residences.

5. Stable and reliable performance, well wind resistance.

6. Meet the mankind healthy bath standard: The material of inner tank is SUS304-2B stainless steel plate; the silica gel ring sealing has a long life against the erosion and it is not harmful to health.
