The Vitodens 200-W wall mounted gas condensing boiler offers high
quality condensing technology with an exemplary price/performance
ratio, excellent heating and DHW convenience, compact dimensions
and a timeless, elegant design.
The Vitodens 200-W consumes less energy, as it also makes use of
the latent heat in the flue gas. The result: Standard seasonal effi-
ciency [to DIN] of up to 98 % (H
your heating bills and also protects the environment.
Both for economy and a long service life, stainless steel is the mate-
rial of choice. That is why the Vitodens 200-W is equipped with a
stainless steel Inox-Radial heat exchanger. It offers the required reli-
ability and ensures permanently high condensing efficiency.
The MatriX cylinder burner, developed and produced in house, has a
wide modulation range down to 1:19 (35 kW). Also integrated is the
Lambda Pro Control Plus combustion controller, which automatically
matches the combustion to changing gas types. This ensures con-
sistently high energy efficiency and offers security in liberalised gas
markets and where gases of biogenic origin are mixed with natural
gas.
The combi versions of the Vitodens 200-W are equipped with a
DHW standby function. This ensures that DHW is always available
at the required temperature.
