After the water tank is full, vacuum tubes absorb solar energy and then heat water inside tank directly. The water heated is stored in the water tank. Tap water inflows into water tank through internal coil, and at the same time tap water absorbs the heat energy from the hot water storaged in the tank by the coil, and turn the tap water into hot water instantly.

Outer tank: Coated color steel sheet or Zinc coated Aluminum

Coil: TP2 

1, The internal coil, which is efficient, and the temperature difference between the import and export of water-side is ≤ 3 ° C.

2, The hot water storage tank is no pressure, safe and reliable, the hot water is that the tap water absorb heat from the tank through the coil in the hot water storage tank to be heated, it can be confined to use.

3, The pressure of hot and cold water is balanced, temperature of water-side is stable.

4, Don’t directly use the hot water in the hot water storage tank, hot water is produced by the tap water which is kept heated through the coil, so water we use is fresh hot water, no pollution.
5, It is easy manipulation
