1.1 Product description
AModulating MatriX cylinder burner with intelligent Lambda Pro
Control Plus combustion controller for clean combustion and
quiet operation
BIntegral diaphragm expansion vessel
CInox-Radial heat exchanger made from stainless steel – for high
operational reliability, a long service life and high heating output
on a very small footprint
DVariable speed combustion fan for quiet and economical opera-
tion
EIntegral variable speed high efficiency circulation pump
FPlate heat exchanger (for gas condensing combi boiler, 1.8 to
35 kW)
GGas and water connections
HDigital boiler control unit
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 % (Hs) [gross cv]. This noticeably reduces
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.
Recommended applications
■ Detached and terraced houses
■ Property development, either modernisation or new build (replace-
ment of water heaters in apartment blocks or prefabricated
houses)
Benefits at a glance
■ Standard seasonal efficiency [to DIN]: Up to 98 % (Hs) [gross cv]
■ Durable and efficient thanks to the Inox-Radial heat exchanger
■ Modulating MatriX cylinder burner, modulating range up to 1:19,
with a long service life thanks to stainless steel MatriX gauze –
resistant to high temperature loads
■ High DHW convenience – combi boilers generally include a
standby function
■ Automatic flue adaptor
■ Energy saving high efficiency circulation pump (compliant with
Energy Label A)
■ New, innovative operating concept employing a colour
touchscreen with plain text and graphic display, commissioning
assistants, displays for energy consumption and alternative opera-
tion from a mobile end device
■ Lambda Pro Control Plus combustion controller for all gas types –
saves on costs by extending the inspection interval to 3 years [in
Germany]
■ Quiet operation thanks to low fan speed
■ Web-enabled through Vitoconnect (accessories) for operation and
service via Viessmann app
Delivered condition
Wall mounted gas condensing boiler with Inox-Radial heat
exchanger, modulating MatriX cylinder burner for natural gas and

Variable speed heating circuit pump in the Vitodens 200-W
The integral circulation pump is a highly efficient pump with substan-
tially lower power consumption than conventional pumps.
The pump speed and consequently the pump rate are regulated sub-
ject to the outside temperature and the switching times for heating or
reduced mode. The control unit transmits the current default settings
to the circulation pump via an internal data bus.
The control unit codes can be used to match the minimum and maxi-
mum speeds and the speed for reduced mode to the existing heating
system.
In the delivered condition, the minimum pump rate (coding address
"E7") and the maximum pump rate (coding address "E6") are set to
the following values:

Note
In conjunction with a low loss header, heating water buffer cylinder
and heating circuits with mixer, the internal circulation pump runs at
a constant speed. The speed can be adjusted subject to demand by
changing codes at the control unit.

Instantaneous standby water heater (gas condensing combi

An instantaneous standby water heater is integrated into the
Vitodens 200-W. When the comfort function is switched ON, the tem-
perature of the instantaneous water heater will be maintained. This
makes DHW at drawing temperature available from the Vitodens
instantly.

If a greater volume of water is required, cold water needs to be
admixed, which reduces the outlet temperature.
The illustrated outlet temperature characteristics are based on a cold

2.1 Product description
AInox-Radial heat exchanger made from stainless steel – for high
operational reliability, a long service life and high heating output
on a very small footprint
BLoading cylinder made from stainless steel
CModulating MatriX cylinder burner with intelligent Lambda Pro
Control Plus combustion controller for clean combustion and
quiet operation
DIntegral diaphragm expansion vessel

KDigital boiler control unit
The Vitodens 222-W is a particularly space-efficient, wall mounted,
gas condensing storage combi boiler for situations where high DHW
convenience is required. The heat cell comprises the proven stain-
less steel Inox-Radial heat exchanger, the modulating MatriX cylin-
der burner and the automatic Lambda Pro Control Plus combustion
controller.
The integral 46 l stainless steel loading cylinder offers the same
DHW convenience as a separate 150 l DHW cylinder with internal
indirect coils. DHW is available immediately at the required tempera-
ture and with high consistency, even simultaneously at different
draw-off points. Apart from the loading cylinder, nearly all vital sys-
tem components such as heating water expansion vessels, pumps
and safety valves are integrated and fully fitted. And all that is with a
total weight of max. 67 kg and in a casing that fits into a standard
600 mm wide kitchen unit space.
The Vitodens 222-W is the ideal product, particularly in new build, as
it can be installed before the screed is put down.
Recommended applications
■ Detached and terraced houses
■ New build (e.g. prefabricated houses and developer projects):

■ High level of DHW convenience: NL (performance factor) up to 1.5
(corresponds to a separate DHW cylinder with approx. 150 l
capacity)
■ Energy saving high efficiency circulation pump (compliant with
Energy Label A)
■ New, innovative operating concept employing a colour
touchscreen with plain text and graphic display, commissioning
assistants, displays for energy consumption and alternative opera-
tion from a mobile end device
■ Lambda Pro Control Plus combustion controller for all gas types –
saves on costs by extending the inspection interval to 3 years [in
Germany]
■ Automatic flue adaptor
■ All system components, such as loading cylinder, (heating water)
expansion vessel, pumps and safety valves are fully fitted.
■ Web-enabled through Vitoconnect (accessories) for operation and
service via Viessmann app
