Food Grade 300L Non Pressurized Vacuum Tube Solar Water Heater With
Painted Steel Shell
Specification:
1. Inner tank material: SUS304-2B food grade stainless steel 0.31mm
2. Outer tank material: stainless steel sheet 201, thickness
0.31mm,
3. Bracket:1.2mm SS 202 stainless steel sheet
4. Vacuum tube: 58mm diameter, 1800mm length,coated by AL-N-AL
5. Insulation layer: 50-65mm polyurethane foam
6. Hail resistance:25mm 7.Heat preservation:72hours
Working Principle:
This type use all-glasses evacuated tubes as the solar collector
for absorbing sun energy and transferring
it into heat energy.
As the different densities of hot water and cold water, the hot
water flows automatically upwards while the cold water flows down.
The water flowing cycle is created in the tube. And the water in
the storage tank is heated from this natural circulation.
The hot water pressure of this non-pressure system is from the
gravity, so it should be installed on the roof or at least 3-4
meters higher than hot water tap.
Or you can install a booster pump to get stronger outlet hot water.
Optional Accessories:
1. Booster Pump (adding the hot water out pressure)
2.Temperature Monitor(showing hot water temperature inside the main
tank)
3. Electrical Heater (as back-up for cloudy or rainy day)
