The Vitodens 200 gas fired wall mounted
boiler offers high quality condensing
technology at a persuasive cost:benefit
ratio. With 8.8 to 26 kW, it achieves a
standard efficiency of up to 107 %.
It is also extremely versatile: for heating
and DHW loading, for open and balanced
flue operation. Furthermore, its compact
dimensions and timeless design make it a
perfect match for any modern living
space.
The stainless steel Inox Radial heating
surface operates with extreme efficiency
on account of its liminar heat transfer
principle. The radial design creates large
heat exchanger surfaces on the smallest
of footprints. The rectangular heating
spiral design with defined gaps results in
a longer laminar flow and therefore
excellent heat transfer. In addition, its
smooth stainless steel surface and
vertical flow path result in effective
self-cleaning.
Benefits at a glance
H Gas fired condensing boiler as central
heating or combination boiler,
8.8 to 26.0 kW.
H Standard efficiency: up to 107 %.
H The stainless steel Inox Radial heating
surface ensures high operational
reliability and a long service life.
H Stainless steel cylinder burner,
modulation range 1 : 3.
H Expansion vessel with 10 litres capacity

New for all Vitodens wall mounted
boilers: the rear venting function. For this,
Viessmann has designed the wall
mounted boilers so that a large water
chamber is available for releasing air.
Result: reduced installation times, simpler
commissioning, permanent operational
reliability and reduced flow noise during
operation.
The stainless steel premix cylinder burner
with a modulation range of 1 : 3 handles
fuel with particularly frugality. It also
reduces emissions. These lie below the
strict flue gas limits set for the "Blue
Angel" certificate of environmental
excellence.
H The emissions meet the limits set for
the "Blue Angel" certificate of
environmental excellence.
H Low power consumption through
variable speed DC fan.
H Vitotronic control units for room
temperature-dependent or weather-
compensated mode, with integral
diagnostic system and Optolink laptop
interface; capable of communicating
with Vitodata.
Application recommendations
Favourable pricing and robust construction
make these systems suitable for:
H Object business in modernisation and
new build (replacement of water
heaters in apartment blocks or
pre-fabricated houses)
H Use in rented accommodation and in
leased properties.
H Particularly easy to install, maintain and
service, due to modular design
generous wiring chamber.
H Space saving, because clearances at the
boiler sides are no longer required.
H Automatic flue gas adaptation for
permanently high efficiency.
H Flexible connections to adapt
installations from third party boilers
enable the easy replacement of
alternative boiler makes.
