For
installations
on
walls
,
balconies
or
balustrades, we recommend you size
the collector area some 20
% greater due
to the steep inclination of the collectors.
Note
Collectors are no replacement for
banisters.
However, collectors may also be
installed on pitched roofs (vacuum tubes
may be positioned at right angles or
parallel to the ridge of the roof).
Viessmann offers universal fastening
systems which can be used for almost
all types of roofing and which simplify
installation on roofs and walls.
Note
The collector system meets the
following static load requirements:
Flat roofs
