A copper coil is installed in water storage tank as the heat exchanger,which designs as 24 - 50 meters length; When water flows into the copper coiler, it absorbs the heat from the water in the tank, so it can bear much higher pressure, there will be a strong and more comfortable shower. Without the tank directly transferring, the water is more clean and healthy. |
