Detailed Product Description

^oThermosyphon solar water heater relies on the natural circulation of water between the controllor and the tank or heat exchanger. As water in the vaccum is heated  it rises naturally into the tank, while cooler water in the tank flows down to the bottom of the vacuum tubes, casing circulation throughout the system.

Technical Specifications:

1. Both of inner and outside water tank shell are made of SUS204-2B food grade stainless steel plates, welded by argon arc. Water is pure and drinkable.

2. Heat insulation of water tanks adopts polyurethane foam, thickness is 55mm.

3.Silicon rings to connect and seal them

4. The tubes and sirpports  are adjustable power bearing is average, and can assure the vacuum tubes touse for a long time.

5. Whole glass vacuum tubes  adopt super hard borax and silica glass.

6. Absorb rate:= 93%, thermal radiation rate:=6%(100^oC)

7. Resist 25mm hail, using life can last 15 years.

8. Temperature when exposed to sun without water : 250^oC, 2.5 hours to boiling if single tube is used.

9.If you use electrical appliances to aid heating, to switch of  the power supply before boiling.

10. To test the water temperature before using, in order to avoid scalding
