Compact Pressure Solar Water Heating Systems

Following are the Main Features of Compact Pressure Solar Water Heating Systems :-
1. Suitable to use in all kinds of climates with electric heater
2. Absorbing heat quickly
3. No worry about being frozen because there is no water running inside the tubes when working
4. Completely automatic operation
5. It can withstand pressure of tap water when it works
6. Without incrusting, long usage life
7. Tubes can be laid for long time under the sun without water in the tank.
8. Multifunction: Bathing, washing, domestic heating
9. One or several glass tubes broken will not influence system work

Working principle
The vacuum tubes absorb and convert solar energy into thermal energy, and transfer to the central heat pipe via the aluminum fin. The heat pipes have tiny amount of purified water sealed inside at depressurized condition. When heated, the water inside the heat pipes vaporizes at low temperature (about 30E C), the vapor rises to the condenser and heat energy is conducted to water (inside the tank). When vapor is cooled down, and becomes condensate, falling to the bottom of heat pipe. By continuously circulating in this way, heat is carried from outside to the water inside the tank.
