 the principle of seperate pressure solar water heater being describing as follows:

the sunny rays shines on the solar  collector tubes. the heat is absorbed by the selective absorption coating of glass tube  .and the heat is transfered  by alluminum fin ,and transfered to heat pipe ,then by the medium within heat pipe to co axial manifold copper pipe ,then to heat exchange in water tank,finally to heat water around water storage tank.
