Structure

Storage tank with coppercoil, assistant tank, exhaust pipe on the top of the tank, vacuum tubes with heat pipe, Optional assistant tank, Reflector, Electric assistant heater

Working principle

One copper coil installed inside the solar tank as the heat exchanger.When cold water flows into the copper coil,it absorbs the heat of the water in the tank via the copper coil therefore the water tank is just a heat storage tank.

Feature

1.No corrosion or scaling

2.Use in any time, it adopts advance design idea and integrates with high efficiency preheated patent technique . So it can warm the cold water rapidly when it flows through special pipe. It can overcome the demerits of traditional SWH such as slow heating, long waiting time

3.Especial for hard water area

4.Popular in Italy S.A.

Advantage

1.Use the coppercoil as the heat exchanger,according with international fashion trend, it is simple to install and use

2.It takes the advantage of the tap water’s pressure, more pressure , more comfortable

3.It can produce hot water with constant temperature, it is safe and comfortable to use

4.The water can be heated rapidly , so it can produce the high quality hot water

5.The water come from the copper coil , so it is clean and drinkable

6.Assistant tank as the feeling tool makes the system feeding water easily
