25 vacuum pipe solar collector with Heat-Pipe head, extra thick vacuum pipe, Heat Pipe head, 25 vacuum pipes with 6-year warranty!

Solar collector

Total solar collector surface: 3.77 m2
Collector useful surface: 2.55 m2
Collector width: 1600 mm
Connection pipes: 2x22 mm copper
Volume: 1.56 l

Diameter of vacuum tubes: 70 mm
Length of vacuum tube: 1800 mm< br />Vacuum tube wall thickness: 1.6 mm
Absorber coating: SS-AL-Nx/Cu three target selective absorption coating
Vacuum tube wall thickness: 1.6 mm
Stagnation temperature: 250 C
Heat-Pipe head diameter: 14 mm extra thick
Heat-Pipe head length: 70 mm

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 their efficiency is slightly better, but they are more expensive. They are the same in value for money.

Operating pressure: 6 bar

Vacuum tube solar collector

Modern solar collector with 25 70mm vacuum tube Heat-Pipe system.

With a blue vacuum tube!

New technology, increased collection surface.

Recommended for approximately 240-liter storage.
For larger storage, we recommend several pieces or several tubular solar collectors .

Reliability, operational safety and longevity are guaranteed by high-quality, corrosion-resistant materials: among others, borosilicate glass, which has excellent heat resistance and a high degree of chemical resistance)
copper is aluminum and stainless steel.

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

The vacuum pipes are connected dry, so there is no direct contact between the heat carrier medium and the glycol-water mixture.
Using it, possible replacement of pipes is possible even with a charged system.

The support frame for a flat or sloping roof, which is also required for assembly, is not included in the price! You can find the solar collector support frame in the optional category.
It is already shown with the support frame in the picture.

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.
