10 Evacuated Tubes, Solar Collector of Solar Water Heater, Vacuum Tubes

This auction includes: 1 set of solar collectors of solar water heater(tube length: 0.5meter, Outer Diameter of Tube: φ58mm, 10 Tubes), including:

• 10 pcs of Evacuate Tubes with heat pipe
• 1 pcs of manifold (10 holes)
• 10 pcs of tube holder
• 1 set of aluminum brackets with bolts and nuts.

(Remark: due to it being difficult to ship after assembly, we have to ship to you before assembly.)

Application

This small solar colletor is suitable for heating 50 50-litre water tank, or 100 liter water tank(with heat element).
Please don't expect it to heat the swimming pool. 
The swimming pool may require several hundreds of these small solar collectors. 
If your swimming pool needs a solar hot water system, please ask the local engineer to calculate how many solar colletors are required, then contact us to buy the solar collectors and other parts.
