4). No water inside the evacuated tubes; the solar water heater can still in service even with several tubes breakage

5). Highly efficient insulation with polyurethane foam;

6). Simple structure, easy to assembly and install;

7). Can be used all year round in the cold climate;

8). Can be used together with auxiliary electric boost;

9). Long service life, can be used over 15 years.
Working Principle

Working principle of compact pressurized solar water heater

Highly Efficient Pressurized Thermosiphon Evacuated Tube Solar Hot Water System

-Solar energy is absorbed and converted into heat energy by the absorption layer of vacuum tubes

-Heat energy is delivered to heat pipe through aluminum wings.


-Working liquid in heat pipe absorbs heat and vapors,it moves towards condenser and releases the latent heat of vaporization .

-As condenser indirectly contacts with water through a copper cap,the heat is passed through it to the water in tank.

-At the end,cold liquid returns to the bottom of heat pipe and repeats the cycle.
