Vacuum pipe for Heat-Pipe system complete, including Heat-Pipe!

Vacuum tube solar collectors generally utilize the sun's energy efficiently, and the vacuum helps minimize heat loss to the environment. The copper insert on the inside of the vacuum tube helps the solar energy to be absorbed and transmitted faster in the system. Solar collectors of this type can be used to produce hot water and supplement heating systems.
This product - due to its fragility - can only be delivered in a unit package.
The diameter of the head of the copper Heat pipe insert is 14 mm, the length of the head is 70 mm , sheath length 55 mm.

Use this product when ordering small quantities (between 1-10). These vacuum tubes - due to their fragility - can only be ordered by personal collection. For personal collection, please provide packaging material! 

Recommended order 10-< strong>15 pieces, or a multiple of these, in which case it can be received and delivered in factory packaging.
