Vitodens 200-W

1.1 Product description

1
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 efficiency
[to DIN] of up to 98 % (H ) [gross cv] / 109 % (H
s
ably reduces your heating costs and also protects the environment.
Both for economy and a long service life, stainless steel is a first choice
material. That is why the Vitodens 200-W is equipped with a stainless
steel Inox-Radial heat exchanger. It offers the required reliability and
ensures permanently high condensing efficiency.
The MatriX cylinder burner, developed and produced in house, has a
large modulation range of up to 1:7 (35 kW). Also integrated is the
Lambda Pro Control combustion controller, which automatically
matches the combustion to changing gas types. This ensures consis-
tently high energy efficiency and offers security in liberalised gas mar-
kets 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.
Recommended applications
■ Detached and terraced houses
■ Property development, either modernisation or new build (replace-
ment of water heaters in apartment blocks or pre-fabricated houses)
