An renewable energy-based water heater is a popular system used for heating water using captured energy from the sun. Unlike conventional solar water heaters, vacuum-sealed tube solar water heaters utilize a series of evacuated glass tubes to collect and transfer heat from the bright shining sun.
The cutting-edge evacuated tubes consist of a translucent glass tube vacuumed and coated with a selective coating to absorb maximum heat from the absorbing radiation of the sun.
The most notable feature of sustainable evacuated tube solar water heaters is their superior performance compared to non-evacuated solar water heater water heaters. Evacuated tubes can retain and exceed a higher temperature at the collector's surface and maintain a higher efficiency rate over time. They are effective even cold and sometimes cloudy climates and can work at temperatures as low as 10°C.
