Panel Collector Viessmann Vitosol 100-FM, 2.3sq.m.

Vitosol 100-FM – high-efficiency flat-plate collector with special ThermProtect absorber coating for overheating protection

The powerful selective flat-plate collector Vitosol 100-FM is the ideal addition to any heating installation. With an absorber area of 2.3 m², the collectors suit every individual requirement.

On an annual average, solar collectors produce up to 60 percent of the energy needed for heating hot water, and they can also be used to support space heating. In combination with a condensing boiler, solar energy can save up to a third of the annual energy needed for heating and hot water.

Benefit from these advantages:

• No more overheating and steam formation when heat is insufficiently drawn off
• Higher efficiency for supporting space heating and domestic hot water heating
• Universal application for installation on pitched and flat roofs, as well as on facades
• Powerful flat-plate collectors with special ThermProtect absorber coating for overheating protection
• Horizontal or vertical collector arrangement is possible

ThermProtect prevents overheating

The intelligent absorber coating protects the collectors from overheating. Viessmann's patented ThermProtect technology switches off the solar collectors when a certain temperature is reached. At temperatures above approximately 75 °C the crystal structure of the absorber coating changes, thermal radiation increases many times over and the collector output is reduced. As a result, the maximum collector temperature is significantly lower and steam formation in the solar circuit is prevented.

As the collector temperature drops, the crystal structure of the coating returns to its original state. After that, more than 95 percent of the solar energy is again absorbed and converted into heat. The remaining five percent is reflected. The change in crystal structure is reversible without limit and the function remains durable throughout the service life.

Lasting tightness and good insulation

The continuous bent aluminium frame and seamless glass fixing guarantee lasting tightness and high stability of the collectors. The back of the collectors is impact- and corrosion-resistant. High-efficiency thermal insulation reduces heat losses, especially in the transitional seasons and in winter.

Easy installation

The collectors are extremely easy to install. The integrated flow and return pipe connections allow simple and secure installation of large collector arrays using flexible stainless steel plug-in connectors. Up to 12 solar collectors can be quickly and easily connected into one collector array. The flat-plate collectors are universal in terms of installation, suitable for mounting on pitched roofs, roof integration or free-standing installation, for example on flat roofs. Viessmann's simplified mounting systems are statically tested and made of corrosion-resistant stainless steel and aluminium components.
