Vitodens 200-W
Vitodens 200-W wall mounted condensing boilers up to 150 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 150 kW or
1
as a cascade with up to eight boilers and a heating output up to
900 kW.
The Inox-Radial heat exchanger made from stainless steel offers high
output on a very small footprint. This enables particularly efficient
operation with standard seasonal efficiency [to DIN] up to 98 %
(H ) [gross cv] / 109 % (H
s
The Vitotronic 300-K cascade control unit regulates up to eight
Vitodens 200-W as a single heating centre. It also automatically
matches the boiler output to the heat demand. This means: Subject to
the prevailing demand, either one boiler modulates or all eight boilers
operate concurrently.
We offer the complete range of matching system components for cre-
ating cascade systems, e.g. control units with up to eight appliances,
fully insulated hydraulic cascades and flue gas headers.
Recommended applications
High heating 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/shopping centres, workshops and industrial prem-
ises, commercial nurseries, garages and DHW heating systems
■ Systems with several heating circuits for underfloor and/or static
radiators in apartment buildings, central heating plants for terraced
houses, office buildings and administration premises – particularly
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 intermediary
floors or in the attic
Benefits at a glance
■ Optional cascade installation with up to eight boilers and up to
900 kW rated heating output
■ Standard seasonal efficiency [to DIN]: Up to
98 % (H ) [gross cv] / 109 % (H
s
■ Durable and efficient thanks to the Inox-Radial heat exchanger
■ Modulating MatriX cylinder burner with a long service life thanks to
stainless steel MatriX gauze – resistant to high temperature loads
■ Easy-to-use Vitotronic control unit with plain text and graphic display
■ The programming unit of the control unit can also be fitted on a wall
mounting base (accessories)
■ Lambda Pro Control combustion controller for all gas types – saves
on costs, with inspection interval extended to 3 years
■ Quiet operation through low fan speed
