Vitodens 200-W
45 to 105 kW
Cascade up to 840 kW
The Vitodens 200-W high specification
boiler is one of the most efficient and
quietest condensing boilers in this sector.
It is now available for commercial applications
up to 840 kW – good news if access is
difficult or floor space is limited, if you prefer
the reassurance of having more than one
boiler running as a back-up or if you want
all the features of this great wall-hung gas
condensing boiler.
It can be cascaded with output ranging from
17 to 840 kW. Up to eight 200-W can be
linked in a single cascade. Simply tell us your
required output and we can supply all the
components you need for the best cascade
combination for your project – see page 7.

Intelligent Lambda Pro gas
management system for optimum
efficiency and performance
The Lambda Pro is designed to work
efficiently irrespective of gas quality – a
factor which will become increasingly
important as imports of international gas
supplies increase.
The Lambda Pro combustion controller works
alongside the burner to constantly monitor
the air to gas ratio. Instead of the gas/air mix
remaining fixed from commissioning, the mix
is self adjusting as required, to maintain
optimum boiler efficiency in relation to the
gas quality – in a similar way to the fuel
management system in a car engine.
The control also replaces the traditional gas
valve control and changing to LPG takes just a
few seconds – with no changing of any parts.
Modulating MatriX pre-mix burner
Developed by Viessmann, the stainless steel
MatriX pre-mix burner burns with thousands
of tiny flames instead of one large one, to
distribute heat cleanly and efficiently to the
heat exchanger. With a modulation range
of 1:4 the heat demand is optimised and
maximum efficiency levels are achieved. The
extremely low NOx and CO emissions meet
or exceed all national clean air regulations and
guidelines.
The stainless steel MatriX mesh ensures
long term reliability.
Inox-Radial heat exchanger
As with all Viessmann wall-hung boilers, the
Vitodens 200-W features Viessmann’s unique
stainless steel heat exchanger, designed for
long term reliability, high performance and
self cleaning.
The design of the heat exchanger ensures
high heat transfer through laminar hot gas
flow across defined gaps. High corrosion
resistance is maintained by the use of high
grade stainless steel 1.4571 and thick
walls. This component is so reliable that it
comes with a 10 YEAR WARRANTY against
corrosion due to products of combustion.
Advanced controls
The Vitodens 200-W is loaded with
features and functions to make installation,
maintenance and servicing easy. These
include in-built software for remote data
communication and monitoring, additional
heating circuits, a solar/heat pump
interface, safety monitor sensors and
automatic commissioning functions.
Weather compensation controls
The Vitodens 200-W is available with
optional weather compensation control (the
Vitotronic 200). It looks at the actual outside
temperature and compares it with the desired
indoor temperature. The flow temperature
is varied suitably to maintain comfort levels.
This keeps the boiler condensing as much as
possible, providing additional fuel savings of
up to 15%.

Cascade controls (Vitotronic 300-K
type MW2B)
The Vitotronic 300-K weather compensated
cascade controller can regulate up to eight
Vitodens 200-W boilers as a single heating
centre. By communicating with the individual
boiler controls, the Vitotronic 300-K ensures
that the boiler output is automatically matched
to the heat demand. As a result, subject to
the demand, more or fewer boilers are fired
to match the load. Up to 4 boilers via LON
communication. Up to 8 boilers via KM Bus.
