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 because it also utilises the
latent heat in the flue gas. Result: Standard efficiency of up to
98 % (H ) / 109 % (H ). It's clear that this will reduce your heating costs
s i
and be good for the environment.
Stainless steel is the only choice of material where economy and a
long service life are required. For this reason, the Vitodens 200-W is
equipped with a stainless steel Inox-Radial heat exchanger. It offers
the required reliability and ensures permanently high condensing effi-
ciency.
The MatriX cylinder burner, developed in-house, has a modulation
range of 1:4. The integral Lambda Pro Control combustion controller
adjusts combustion automatically to changing gas types. This ensures
consistently high energy efficiency and offers security for the future in
liberalised gas markets and where gases of biogenic origin are mixed
with natural gas.
The Vitodens 200-W is also available with a variable speed high effi-
ciency DC pump, which reduces power consumption by more than
50 %.
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.
