Detailed Product Description

Solar Energy Collector

Evacuated tubes convert solar energy into thermal energy that is Transferred to copper U pipes by an aluminum fin with high solar Energy absorption and low heat radiance loss. Liquid (pure water Or glycol solution) in the U pipe heats up, and the U pipe conducts Thermal energy to the water inside the storage tank through internal Copper coils Uses an electrical heater to heat water during cloudy days or at night As the water temperature can be adjusted using an automatic controller, The tubes and supports are adjustable, power bearing is average, and can assure the vacuum tubes to use long time. Whole glass vacuum tubes adopt super hard borax and silica glass. Absorb rate: =93%, thermal radiation rate: =6%(100) Resist 25mm hail, using life can last 15 years. Temperature when exposed to sun without water: 250, 2.5hours to boiling if using single tube. If you use electrical appliances to aid heating, to switch off the power supple before bathing. To test the water temperature before using, in order to avoid scalding.
