1.1 Product description
AModulating MatriX cylinder burner with intelligent Lambda Pro
Control combustion controller for clean combustion and quiet
operation
BIntegral diaphragm expansion vessel
CInox-Radial heat exchangers made from stainless steel - for high
operational reliability, a long service life and high output on the
smallest footprint
DVariable speed combustion fan for quiet and economical opera-
tion
EIntegral two-stage circulation pump or variable speed high effi-
ciency DC pump
FPlate heat exchanger (for gas condensing combi boilers, 6.5 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 because it also utilises the
latent heat in the flue gas. Result: Standard efficiency of up to
98 % (Hs) / 109 % (Hi). It's clear that this will reduce your heating costs
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.
Recommended applications

■ Property development, either modernisation or new build (replace-
ment of water heaters in apartment blocks or pre-fabricated houses)
■ Usage in rented and leased properties
Benefits at a glance

fees by extending the inspection intervals to up to five years [in Ger-
many]
■ Quiet operation through low fan speed

Variable speed heating circuit pump in the Vitodens 200-W
The integral circulation pump is a highly efficient DC pump with more
than 50 % less power consumption than conventional pumps.
The pump speed and consequently the pump rate is regulated subject
to the outside temperature and the switching times for heating or
reduced mode. The control unit transmits the current default speed via
an internal data BUS to the circulation pump.
Individually match the minimum and maximum speed plus the speed
for reduced mode to the existing heating system using the control unit
codes.
In the delivered condition, the minimum pump rate (coding address
"E7") is set to 30 %. The maximum pump rate (coding address "E6")
is set to the following values:

Instantaneous standby water heater (gas condensing combi
boiler)
An instantaneous standby water heater is integrated into the Vitodens
200-W. When the convenience function is switched ON, the tempera-
ture of the instantaneous water heater will be maintained. This makes
DHW at drawing temperature available from the Vitodens instantly.

The diagram illustrates the changes in the outlet temperature, subject
to the flow rate at the tap.
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

The Vitodens 222-W is a particularly space-efficient, wall mounted,
gas compact condensing boiler for high DHW demands. The heat cell
comprises the proven stainless steel Inox-Radial heat exchanger, the
modulating MatriX cylinder burner and the automatic Lambda Pro
Control combustion controller.
The Vitodens 222-W is also available with a variable speed high effi-
ciency DC pump, which reduces power consumption by more than
50 %.
The integral 46 litre stainless steel primary store offers the same DHW
convenience as a separate 150 litre DHW cylinder with internal indirect
coils. DHW is available immediately at the required temperature and
with high consistency, even simultaneously at different draw-off points.
Apart from the primary store, nearly all vital system components such
as heating water expansion vessels, pumps and safety valves are
integrated and fully fitted. All that with a total weight of only 60 kg (4.8
to 19.0 kW) and in a casing that fits into a standard kitchen unit width
of 600 mm.
The Vitodens 222-W is the ideal product, particularly in new build, as
it can be installed before the screed is put down.

Variable speed heating circuit pump in the Vitodens 222-W
The integral circulation pump is a highly efficient DC pump with more
than 50 % less power consumption than conventional pumps.
The pump speed and consequently the pump rate is regulated subject
to the outside temperature and the switching times for heating or
reduced mode. The control unit transmits the current default speed via
an internal data BUS to the circulation pump.
Individually match the minimum and maximum speed plus the speed
for reduced mode to the existing heating system using the control unit
codes.
In the delivered condition, the minimum pump rate (coding address
"E7") is set to 30 %. The maximum pump rate (coding address "E6")
is set to the following values:
