RTTC Solar Water Heater

Non-pressured solar water heater relies on the natural circulation of water between the collector and the tank. Hot water rises naturally into the tank, while cold water flows down from the tank to the vacuum tubes, causing circulation throughout the system.

Advantages: Using the copper coil as the heat exchanger can produce hot water with constant temperature, it is safe and comfortable to use. It takes advantage of the tap water pressure which can produce a strong water flow. The copper coil heat exchnager makes the water heat rapidly, and is not limited by the tank capacity so it can produce more hot water than the general models.
