WORK PRINCPLE:

The highly efficient solar vacuum tubes absorb the sun's heat and transfer it to the water in the tank. As the water in the tank is heated, it rises up to be replaced by cooler water which is heavier. The solar heated water is then stored ready to use. The insulation layer is 50-60mm in thickness, which can well keep the warmth within the storage tank, whenever you want to use, there is always hot water.
