Operational Principle
The ESWH are all-glass evacuated solar domestic water systems
combined with heat pipes. The selective coating in the inner cover of the evacuated tubes ensures
high energy absorption and low heat radiance losses, which converts solar energy into heat energy
and transfers this energy to the heat pipe by an aluminium fin. The liquid in the heat pipe changes
into vapour and rises to the condenser. The heat conducts away to the water inside the tank and
the vapour in the heat pipe again becomes liquid, returning to the base of the heat pipe. This
continuous circulation transfers heat from the heat pipe to the cold water in the tank. This process
will continue as long as the sun is heating the collectors.
Assembly Instruction
The reflector angle of ESWH heater can be chosen between 30°or 45°.
Reflector Assembly
1. Place the module-type reflectors side by side.
2. Position the base bracket with larger parallel slots at the bottom. Overlap the holes with those in
the triangular end of reflector frame. Fasten with the nuts and bolts provided.
3. Position the narrow sides of the top reflector bar upwards and overlap the holes with those in the
square end of the reflector frame. Fasten with the nuts and bolts provided.
Frame Assembly
Cross-connect the diagonal bars with the right and left upright supports.
In the JR-200 model, connect the two sets of crossed diagonal bars to the middle upright support.
Then connect to right and left upright supports.
