Descripción del producto

Workingprinciple:
The all glass vacuum tubes act as the heat-absorber element, the high vacuum degree of the clearance between the outer and inner tube can reduce the heat emission, which is caused by convection and conduction of the layer films, to a very low rates. Due to the difference of density between the hot water and the cold water, a cycle will be created in the tube which ascends hot water and descends cold water to keep the natural circulation. Through this circulation, the water in the tank will be heated.
