Vitodens 200-W
1.1 Product description
1
Vitodens 200-W wall mounted condensing boilers up to 105 kW are
especially suitable for installation in apartment buildings and commer-
cial or public buildings. For these, the Vitodens 200-W offers an afford-
able, space-saving solution – either as a single unit up to 105 kW or
as a cascade with up to four boilers and an output up to 420 kW.
The Inox-Radial heat exchanger made from stainless steel offers high
output in the tightest of spaces. This enables particularly efficient oper-
ation with standard efficiency up to 98 % (H
The Vitotronic 300-K cascade control unit regulates up to four Vitodens
200-W as a single heating centre. In this way, the boiler output is auto-
matically matched to the heat demand. This means subject to the pre-
vailing demand, either one boiler modulates or all four boilers operate
concurrently.
For the construction of cascade systems, we offer perfectly matching
system design, e.g. control units with up to four appliances, fully insu-
lated hydraulic cascades or flue gas headers.
Recommended applications
High output from a compact, user-friendly wall mounted boiler, suitable
for the following applications:
■ Systems with few, large-demand consumers, e.g. fan heaters in
supermarkets/markets, workshops and industrial premises, nurser-
ies, garages and DHW heating systems
■ Systems with several heating circuits for underfloor and/or static
radiators in multi-occupancy dwellings, central heating plants for ter-
raced houses, office buildings and administration premises - partic-
ularly suitable for attic heating centres
■ Heating of public buildings, such as sports and multi-purpose halls,
schools, kindergartens
■ Suitable for installation in basement boiler rooms, on single floors or
in the attic.
