Pre-Heating Pressurized Solar Water Heater
The vacuum tubes absorb the sunlight and turn it into the heat energy, heating the water in the tubes. Depend on the thermosiphon principle, the hot water from the tubes goes into water tank, while the cold water from the tank goes down to the tubes.
People do not use the water from the water tank directly. The cold water comes into the copper exchanger, be heated, then goes out from other side for people use.
It takes the advantage of the tap water's pressure
Completely automatic operation
The water can be heated rapidly
Use the copper coil as the heat exchanger, simple to install and use
No risk for corrosion or scale deposit, best option for inferiority water area
