200L Copper Coil Heat Exchanger Pre-Heating Solar Water Heater

Copper coil solar water heater is the device which one copper coil is installed inside the tank as the heat exchanger. When 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 as heat storage tank.


Advantage
1. Use the copper coil 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. Assitant tank as the feeling tool makes the system feeding water easily.
