Solar Water Heater
Compact Thermosyphon Solar Water Heater with Low Pressure
Key Specifications/Special Features of Solar Water Heater:
- Inner water tank shell is made of SUS 304-2B food grade stainless steel plates and outer tank shell is made of color steel plates, welded by argon arc
- Water is pure and drinkable
- Heat insulation of water tanks adopts polyurethane foam and thickness is 55mm
- Silicon rings to connect and seal them
- Tubes and supports are adjustable
- Life of vacuum tubes is 15 years
- Whole glass vacuum tubes adopt super hard borax and silica glass
- Absorption rate: 93%
- Thermal radiation rate: 6%
- It resists 25mm hail and the using life of whole system can last for 15 years
- Temperature when exposed to sun without water: 250°C, 2.5 hours to boiling point if using single tube
- If you use electrical appliances, it will begin to work when the temperature of water is below 60°C and will switch off automatically when temperature reached 60°C
- Have to test water temperature before using, in order to avoid scalding
