Tec hnology
Vitodens 200, WB2B – 31 to 370 MBH
Industry-leading condensing technology for ultimate performance, reliability and comfort
The Vitodens 200 is ENERGY STAR®
qualifi ed and EcoLogo certifi ed. By
choosing the Vitodens 200, you are
helping to promote cleaner air and a
healthier environment.
Intelligent combustion control
The Vitodens 200 features the intelligent
Lambda Pro combustion management system,
which automatically adapts combustion
to changing gas qualities and operating
conditions. Even if the gas composition
fl uctuates or the gas type is changed, Lambda
Pro quickly adjusts the boiler to the new
conditions. This unique function becomes
increasingly important as gas supplies vary in
quality and heating value.
With your new Vitodens 200 boiler, your
monthly heating bills will be signifi cantly
reduced without compromising your warmth,
comfort and reliability.
Dependable by design
At the core of the Vitodens 200 are the
Viessmann made stainless steel InoxRadial heat exchanger and MatriX cylinder
burner. Together, they deliver long lasting
performance and optimal operational value
(see diagram for more information).
Comfort control
The Viessmann Vitotronic control provides
user-friendly management of the entire heating
system and ensures economical performance
and maximum comfort at all times. The outdoor
reset function automatically adapts the boiler
operating temperature to the changing outdoor
temperature. This reduces fuel consumption
without compromising your warmth and
. Plus, with system control for multiple
comfort
zone space and DHW heating, the Vitotronic
offers even greater heating fl exibility without
additional external controls.
Your environmental choice
The Vitodens 200 is your environmentally
friendly choice for all applications. The lowemission MatriX cylinder burner guarantees
clean, low-NOx combustion, while Lambda
Pro ensures maximum performance. With the
Vitodens 200 you can actively contribute to
protecting the environment, while protecting
your wallet too.
Strength in numbers
As many as eight Vitodens 200 gas-fi red
condensing boilers can be combined in a single
*
prefabricated cascade system
, with inputs up
to 2960 MBH. A cascade system fi res boilers as
required to precisely match load during periods
of fl uctuating heating demand.

A cascade system can also prevent interruption
of heating plant operation, with multiple boilers

What is Lambda Pro?
By continuously monitoring the fl ame quality of the MatriX
cylinder burner, the Lambda Pro combustion management
system automatically adjusts the gas and combustion air
ratio. Without any manual adjustments or conversions, the
Vitodens 200 always maintains optimal performance.
