All Stainless steel ETC low pressure Solar Water Heaters Quality Choice

All Stainless steel low pressure solar water heater

Brief Introduction of Sunny Water

1) The products use super heat condition pipe and has a good effect of heat exchange. 

2) The insulation layers use the up-to-date technology and has a good effect of temperature preservation which allows the water to stay warm for about 70 hours

3) Superior heat-preservation ensured by one-off molding polyurethane foam with thickness 50-60mm

4) Stable and reliable performance, well wind resistance

5) Meet the mankind healthy bath standard, the material of inner tank is SUS304-2Bstainless steel plate, the silica gel ring sealing has a long life against the erosion and it do no harm to health.

Advantages of Sunny water 

1) Highly efficient zbsorber of high performance with daily average effciency over 40%-50%

2) Start up quickly heat pipe transfer the heat energy into the storage tank in one condition

3) With stand pressure of 0.2Mpa,can be connected directly with city water pipe

4) Highly efficient insulation with polyurethane foam

5) Can be used all year round even in the cold weather

6) Automatically controlled

7) Highly heat absorber and less in heat losing

8) For both flat roof and slope roof

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.
