Viessmann flat plates have an absorber area of 2.5sqM and are available in portrait (V) or landscape (H) versions
As the roof fixing options for Viessmann are very complex, it is impossible to list all the variants here.
Please note that the 100-FM is only suitable for on-roof mounting. For in-roof please go to the Viessmann 200-FM
