Aluminum Alloy Solar Water Heater Low Pressure Bearing Vacuum Tubes Solar Water Heater:
*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 transfer sun energy into heat energy by 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 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.
