In each vacuum tube there is a U pipe with direct flow-through that is connected to the header pipe inside manifold. This U pipe is seamed in an aluminum heat transfer fin in the interior of vacuum tube that transmits the heat from the interior tube to the U pipe.
The liquid (usually a glycol-water antifreeze mixture) in the metal U pipe is heated, and conducts the heat energy to the water inside the storage tank through plate exchanger or internal spiral copper coils.

U

1) Especial used for the balcony solar water heating system.

2) Can be connected with the existing heating device.

3) Can be integrated with the architecture perfectly.

4) Humanized design, no water directly flowing in the tubes, enabling the system still workable in case of occasional tube breakage.
