Vitosol 200-T

Vacuum tube collectors with heat pipe technology

With the Vitosol 200-T vacuum tube collector, Viessmann increases the reliability of solar collectors to the extent that they can be installed anywhere. This collector can be
installed vertically and horizontally at any angle between 0 and 90 degrees. It is as suitable for private as for commercial systems. Here, the dry connection of the heat pipe tubes inside the header and the small amount of fluid inside the collector ensure particularly high operational reliability. The collector is available either with 20 tubes (= 2 m2) or with 30 tubes (= 3 m2).

Heat pipe principle for high operational reliability

In heat pipe systems, the solar medium does not flow directly through the tubes.  Instead, a process medium evaporates in the copper pipe below the absorber and  transfers the heat to the heat transfer medium via a heat exchanger.

Making the most of solar energy

To convert the maximum amount of solar energy into heat, every tube can be optimally aligned towards the sun, which maximises energy utilisation. The highly effective thermal insulation in the header casing minimises heat losses, particularly during spring and autumn, and through cold winters.

Quick and easy installation

Standard installation material made of stainless steel simplifies collector installation. During maintenance, an innovative plug-in system allows tubes to be replaced quickly without the need for tools. Corrugated stainless steel plugin connectors make the installation of several collectors in series very much easier than the connection by conventional plumbing methods.

Take advantage of these benefits:

  • Universal application through installation in any location, horizontal or vertical, from 0 to 90 degrees on rooftops, walls or freestanding
  • Easy and safe connection of the individual tubes through an innovative plug-in system
  • The absorber surfaces, which are integrated into the vacuum tubes, are not susceptible to contamination
  • Tubes can be rotated for optimum alignment with the sun, thereby maximising the energy yield
  • Highly effective thermal insulation of the header casing for minimum thermal losses
  • Easy assembly through the Viessmann fixing system and corrugated stainless steel connectors
  • Reduced strain in the heat medium during stagnation due to less volume and faster drainage
  • "Dry connection" allows replacement of individual tubes without draining the system
