10-pipe Big-Pipe vacuum pipe Heat-Pipe solar collector solar collector 10 vacuum pipes 6-year warranty, good price!

Vacuum tube solar collector Big-Pipe 10 tubes

Total solar collector surface: 1.60 m2
Collector useful surface: 1 m2< /span>
Collector width: 895 mm
Connecting pipes: 2x22 mm copper
Space volume: 4.85 l

Vacuum tube diameter: 58 mm
Vacuum tube length: 1800 mm< br />Vacuum tube wall thickness: 1.6 mm

Vacuum tube wall thickness: 1.6 mm
Stagnation temperature: 250 C
Big-Pipe (Heat-Pipe) head diameter: 24 mm extra thick
Big-Pipe (Heat-Pipe) head length: 70 mm< /p>

Note:
The head of the so-called Big-Pipe insert has a larger heat transfer surface, ( the diameter is 24 mm instead of 14 mm) so they are more efficient, but more expensive. They are the same in terms of value for money.

Modern, 10-pipe Big-Pipe (Heat-Pipe) system solar collector

With a blue vacuum tube!
New technology, increased heat transfer surface.
Recommended for approximately 120 liter containers.
For larger storage, we recommend several pieces or several tubular solar collectors.
Reliability, operational safety and long service life are ensured by the high quality,guaranteed by corrosion-resistant materials: among others, borosilicate glasswhich has excellent heat resistance and high chemical resistance),
copper is aluminum and stainless steel.
The vacuum pipes are connected dry, so between the heat carrier medium and theglycol-water mixture there is no direct connection.
It can be used to replace the pipes even with a charged system.

The product does not include connecting pipes, roof hook and antifreeze. For health reasons, we do not recommend the toxic antifreeze, but the solar antifreeze found in our products.
Usually 10-15 liters of concentrate is sufficient.

The product is delivered disassembled in a cardboard box.
Easy installation and maintenance
