Vacuum tube (New type patent product) 1.Thermal efficiency increase by 5% than Tri-element vacuum tube solar water heater .

Vacuum tube, it is our New type patent product.

1) Utilizing nanotechnology ,Jumbo-light focused vacuum tube adopt interior reflector on base of Tri-element vacuum tube, which make solar collector will absord sunshine from 360 angle effectively. So will increase absorbable efficiency largely.

 2)  Thermal efficiency increase by 10% -15% than normal vacuum tube solar water heater , by 5% than Tri-element vacuum tube solar water heater under same shushine and weather condition.
