Pre-heated Copper Coil Solar Water Heater / Pressurized Solar Water Heater
One copper coil 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 a heat storage tank.
Instant heat exchange and plentiful warm water for use
make sure the water quality
works with pressure
output water temperature is stable,so it is very comfortable and safe to use
hot and cold water flow is seperated
the copper coil is with high quality and high grade material
easy to operate,reliable to use and intelligent to work

How it works:
1, Connect the copper inlet /outlet with tap water piping directly. Water is feed automatically by the water pressure. The vacuum tube absorb the sun energy and transfer the heat to the tank .Then tank water warm the water of coil in a short time.
2, Solar absorption: solar radiation is absorbed by the vacuum tubes and converted into heat.
3, Solar heat transfer: The tank water conduct the heat from within the solar tube up to the coil.
