solar water heater

This type uses the all-glass evacuated solar collector tubes as the heat-absorbing element

The high vacuum degree of the clearance between the outer and inner tube reduces the heat emission which is caused by convection and conduction.The layer films(coating)of the all-glass evacuated tubes transfer the sun energy into heat energy.This high absorption and low emittance rate of Sangli's layer film is unique.Depending on the different density between hot water and cold water,a water cycle is created in the tube.Hot water flows automatically upwards while the cold water flows down.The water in the storage tank will be heated from this natural circulation.

Specification:

1.No-pressure intergrated common type2.Water tank:stainless steel,SUS304,thickness:0.5mm3.Frame:Coated galvanized steel,thickness:1.5mm4.Insuation:Polyurethane,thickness:50mm5.Vent connection(inch):1/26.Temperature of water can be heated to:85 degree,need 3-4hours.7.In rainy days:It keep temperature for 72 hours(But the temperature will decrease about 5-10 degree)8.Electric heater:When there's no sun,it can be heated by electric heater.(We will add or not as to your requests)
