Vitodens 200-W
Vitodens 200-W wall mounted condensing boilers up to 150 kW are
especially suitable for installation in apartment buildings and com-
mercial or public buildings. For such cases, the Vitodens 200-W
offers an affordable, space saving solution – either as a single unit
1
up to 150 kW or as a cascade with up to 6 boilers and a heating out-
put up to 594 kW.
The Inox-Radial heat exchanger made from stainless steel offers
high output on a very small footprint. This enables particularly effi-
cient operation with standard seasonal efficiency [to DIN] of up to
98 % (H ) [gross cv].
s
The Vitotronic 300-K cascade control unit regulates up to 6
Vitodens 200-W as a single heating centre. It also automatically
matches the boiler output to the heat demand. This means: Subject
to heat demand, either one boiler modulates or all 6 boilers operate
concurrently.
We offer the complete range of matching system components for
creating cascade systems: control units, 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 heating and/or
static heating surfaces 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 6 boilers and up to 594 kW
rated heating output
■ Standard seasonal efficiency [to DIN]: Up to 98 % (H
■ 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 operate Vitotronic control unit with plain text and graphic
display
■ Lambda Pro Control combustion controller for all gas types – sav-
ing fees by extending the inspection interval to 3 years [Germany]
■ Quiet operation thanks to low fan speed
Factory setting
Wall mounted gas condensing boiler with Inox-Radial heat
exchanger, modulating MatriX cylinder burner for natural gas and
LPG to DVGW Code of Practice G260 [Germany], plus wall mount-
ing bracket.
Fully plumbed and wired. White epoxy-coated casing.
