Working principle
When the discrepant temperature of the solar collector and water tank reaches the set value, the controller shall start the circulation pump automatically. Vacuum tube is composed of inner and outer glass pipe, inspiratory layer, vacuum space, inspriatory membrane. The surface of inner and outer glass tube is plated with selective absorption layer. The layer absorb the solar energy and turn it into heat energy, aluminum fins pass the heat energy to the heat pipe, the liquid medium in the heat pipe is heated by the heat energy, then turns into the gas medium, the gas medium flows up to the top of the heat pipe (condenser) and transfer the energy to the copper manifold header heat pipe. At the same time the gas medium turns into the liquid when cooled, then flows down. Keep recycling. In case the temperature of the water tank does not reach Tmax, then start the auxiliary heating device.
Features
1. Collectors are separated from the storage tank. The tank can be put anywhere of the house,so the whole system is harmonious with the building2. Absorbing heat quickly
3. No worry about being frozen because there is no water running inside the tubes when working4. Completely automatic operation5. It can withstand pressure of tap water when it works
6. Without incrusting, long usage life7. Multifunction: Bathing, washing, domestic heating8. One or several glass tubes broken will not fluence system work
9. Tubes can be laid for long time under the sun without water in the tank.
10. Suitalbe to use in all kinds of climates with electric heater
11. The tank inside the building, the hot water loses less energy than the normal one
12. The upright tank can reduce the cold and hot water to mix together
13. Guarantee: Water tank for 2 years, tube and frame for 5 years
