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

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

1). 10 pcs of Evacuate Tubes with heat pipe

2). 1 pcs of manifold (10 holes)

3). 10 pcs of tube holder

4). 1 set of aluminum bracket with bolts and nuts.

Application: It can be used as solar collector for solar hot water heating system, for training project, or demon collectors, or as small solar collector for the water heating system at home. etc.
This small solar colletor is suitable for heating 50 liter 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 this small solar collectors.
If your swimming pool needs the solar hot water system, please ask the local engineer to calculate how many solar colletors required, then contact us to buy the solar collectors and other parts.
