With fluctuating energy prices and a growing concern for the environment, it pays to
modernize your outdated gas-fired boiler. You will save money, and the environment too.
At approximately 40%, domestic heating
accounts for the greatest proportion
of energy consumption and most CO
emissions. By replacing an outdated
heating system with a modern solution,
you can significantly improve energy
utilization – reducing fuel consumption
as well as harmful greenhouse
gas emissions.

Reduce unnecessary waste
There are an estimated 20 million homes in
the United States with heating systems 20
†
years of age or older
. For most of them, a
significant share of energy and money go
to waste unnecessarily every year due to
outdated technology and an improperly sized
system. Along with wasting energy, these
boilers contribute to climate change by
needlessly releasing harmful CO
emissions.

By replacing an outdated system with a
gas-fired condensing boiler, a homeowner
*
can expect to save as much as 30%
on
their annual heating bills. This not only
results in significant cost savings, but also
environmental savings with reduced CO
2
emissions.
A modern solution
With the Vitodens 100-W, Vitodens 200-W and
Vitodens 222-F Series, we offer a complete
line of gas-fired condensing boilers.
Equipped with a corrosion-resistant stainless
steel Inox-Radial heat exchanger, our Vitodens
Series boilers can safely operate at extremely
low boiler water temperatures. For you, this
greater energy utilization translates into
reduced heating costs as well as a smaller
environmental footprint. Plus, our Vitodens
Series gas-fired condensing boiler comes
ready for the future by automatically adjusting
to all gas types – including conditioned biogas.
It doesn’t stop there
Our extensive product portfolio lets you take
energy savings a step further. Reduce your
energy costs by integrating domestic hot
water production with your heating boiler,
and manage the entire system with one of
our control solutions. Or put the sun to work
for you by adding a solar thermal package.
With the entire system from one source,
you don’t have to compromise: total system
performance and additional energy savings go
hand-in-hand.
The Vitodens 200 gas-fired condensing boiler
is prepared for the use of conditioned biogas.

Advanced Condensing Technology
A gas-fired condensing boiler is one of the most economical and clean ways to generate
heat and can reduce your monthly heating bills, as well as your environmental footprint.
Condensing technology not only utilizes the
heat from the combustion of gas, but also the
unused heat that would escape up the
chimney with a conventional heating system.
Condensing boilers achieve excellent efficiency
by extracting almost all of the heat contained
in the flue gases and converting it into
additional heating energy. To do this,
Viessmann condensing boilers are equipped
with a corrosion-resistant, stainless steel InoxRadial heat exchanger, which cools the flue
gases before they are routed into the chimney.
By doing this, the water vapor contained
within the gases is deliberately condensed,
and the additional heat released is transferred
into the heating system.
Through the condensation of the water vapor contained in the flue gas, additional heat is extracted from the flue gas and
added back into the heating system. This increases efficiency and lowers your heating costs and environmental impact.
