Viessman Solar Thermal
About Viessman
Viessmann's domestic product range has been built around a long established reputation for high quality commercial heating systems. Viessmann has utilised its extensive knowledge and expertise to develop domestic heating products that define the quality benchmark for other brands. Viessmann manufactures all of its own products and most controllers to ensure that the drive for quality remains throughout the entire range and that there are additional benefits from combining its heating technologies.
Viessman have more than 30 years experience in the development and manufacture of solar thermal systems, and are now considered the market leader in Europe for Solar DHW Systems.
Viessman Evacuated Tube Collectors
Viessmann solar collectors are designed for an exceptionally long service life, guaranteed by the use of high-grade, corrosion-resistant materials such as glass, aluminium, copper and stainless steel.
Viessman manufacture two models of evacuated tube panels under the "Vitosol" name which are suited to domestic and commercial installations: The Vitosol 200-T and the Vitosol 300-T.
Vitosol - Highly efficient tube collectors with plug-in system.
Vitosol tube collectors are delivered in a modular design. An innovative plug-in system enables the simple and quick installation of the tubes, without requiring tools or having to open the header casing. Plug the tubes into the manifold - click - done. The stainless steel corrugated plug-in connectors interconnect the individual collectors. The individual tubes can then be rotated for optimum alignment with the sun.
The Sol-titanium coated absorbers collect a vast amount of solar energy and thereby ensure high efficiency. The vacuum in the tubes guarantees very effective thermal insulation. There are therefore almost no losses between the glass tubes and the absorber, enabling the collector to convert even low levels of solar radiation into useful energy.
The Vitosol range incorprates heat pipe technology which provides particularly high operational reliability and gives the collector reliable protection against overheating. In heat pipe systems, the solar medium does not flow directly through the collector tube. Instead, a process medium, which circulates in the copper pipe below the absorber, evaporates when subjected to solar irradiation, and transfers the heat to the solar medium via a heat exchanger.
Vitosol 200-T - Direct flow vacuum tube collector
The Vitosol 200-T is a direct flow vacuum tube collector that is ideal for installations in any location. The new design of the header casing enables the Vitosol 200-T to blend harmoniously into the overall appearance of the roof.
Benefits at a glance
- Highly efficient, direct flow vacuum tube collector for high solar energy utilisation
- Universal application through vertical or horizontal installation in any location, on rooftops, walls and freestanding installation
- Easy and safe connection of the individual tubes through an innovative plug-in system
- The absorber surfaces, which are integral to 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 installation through the Viessmann fixing system and corrugated stainless steel plug-in pipe connectors
- The flow and return connection on one side through the integral header inside the header casing minimises the effort required in connecting the pipework
- Attractive collector design, header casing in RAL 8019 (brown)
Vitosol 300-T - Vacuum tube collector
One of the specific applications of the Vitosol 300-T is in systems with long phases of high solar irradiation without heat transfer, so called stagnation phases. The dry connection of the heat pipe tubes inside the header and the integral temperature limiter ensure particularly high operational reliability.
Benefits at a glance
- Highly efficient vacuum tube collector based on the heat pipe principle for high operational reliability
- The absorber surfaces with Sol-titanium coating, which are integrated into the vacuum tubes, are not susceptible to contamination
- Efficient heat transfer through fully encapsulated condensers inside the twin-pipe Duotec heat exchanger
- 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
- Integral temperature limiter controls the heat flow at very high collector temperatures
- Easy installation through the Viessmann assembly and connection systems
- Attractive collector design, header casing in RAL 8019 (brown)
