Gas Condensing
Technology
The Vitodens 200 is ENERGY STAR®
qualified and EcoLogo certified. By
choosing the Vitodens 200, you are
helping to promote cleaner air and a
healthier environment.
Intelligent combustion control
The Vitodens 200 is ready for the future
thanks to its intelligent Lambda Pro combustion
management system, which automatically
adapts combustion to changing gas qualities
and operating conditions. Even if the gas
composition fluctuates or the gas type is
changed, Lambda Pro quickly adjusts the boiler
for maximum efficiency at the new conditions.
This unique function becomes increasingly
important as gas supplies vary in quality and
heating value.
With your new Vitodens 200 operating at the
highest efficiency at all times, your monthly
heating bills will be significantly reduced
without compromising your warmth, comfort
and reliability.
Efficient by design
At the core of the high-efficiency Vitodens 200
is the Viessmann stainless steel Inox-Radial
heat exchanger and MatriX cylinder burner.
Together, they allow the greatest amount of
heat extraction to be achieved with minimal
loss (see diagram for more information). This
equates into an unbeatable efficiency of 98%
at full modulation.
Comfort control
The powerful 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 comfort.Plus, with system control
for multiple zone space and DHW heating, the
Vitotronic offers even greater heating flexibility
without additional external controls.
Your environmental choice
The Vitodens 200 is your efficient and
environmentally-friendly choice for all
applications. The low-emission MatriX cylinder
burner guarantees clean, low-NOx combustion,
while Lambda Pro ensures the highest
efficiency at all times. 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-fired
condensing boilers can be combined in a single
prefabricated cascade system*
, with inputs
up to 2960 MBH. A cascade system fires
boilers as required to meet fluctuating heating
demands; it maintains maximum efficiency at
all times by precisely matching the load.
A cascade system can also prevent interruption
of heating plant operation, with multiple boilers
available as back-up.

What is Lambda Pro?
By continuously monitoring the flame quality of the MatriX
cylinder burner, the Lambda Pro combustion management
system can ensure maximum efficiency by automatically
adjusting the gas and combustion air ratio. Without any
manual adjustments or conversions, the Vitodens 200
always performs at optimal efficiency.
