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 heating output
on a very small footprint
DVariable speed combustion air fan for quiet and economical oper-
ation
EIntegral, variable speed high efficiency circulation pump
FPlate heat exchanger (for gas condensing combi boiler, 5.2 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 efficiency
[to DIN] of up to 98 % (Hs) [gross cv] / 109 % (Hi) [net cv]. This notice-
ably reduces your heating costs and also protects the environment.
Both for economy and a long service life, stainless steel is a first choice
material. That is why the Vitodens 200-W is equipped with a stainless
steel Inox-Radial heat exchanger. It offers the required reliability and
ensures permanently high condensing efficiency.
The MatriX cylinder burner, developed and produced in house, has a
large modulation range of up to 1:7 (35 kW). Also integrated is the
Lambda Pro Control combustion controller, which automatically
matches the combustion to changing gas types. This ensures consis-
tently high energy efficiency and offers security in liberalised gas mar-
kets 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 pre-fabricated houses)
Benefits at a glance
■ Standard seasonal efficiency [to DIN]: up to
98 % (Hs) [gross cv] / 109 % (Hi) [net cv]
■ Durable and efficient thanks to the Inox-Radial heat exchanger
■ Modulating MatriX cylinder burner with a long service life thanks to
stainless steel MatriX gauze – resistant to high temperature loads
■ High DHW convenience – all combi boilers include standby function
■ Energy-saving high efficiency circulation pump (compliant with
Energy Label A)
■ Easy-to-use Vitotronic control unit with plain text and graphic display
■ The programming unit of the control unit can also be fitted on a wall
mounting base (accessories)
■ Lambda Pro Control combustion controller for all gas types – saves
on costs, with inspection interval extended to 3 years
■ Quiet operation thanks to low fan speed

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
via an internal data BUS to the circulation pump.
Individually match the minimum and maximum speeds 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") and the maximum pump rate (coding address "E6") are 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 Vitodens 222-W is a particularly space-efficient, wall mounted,
gas condensing storage combi boiler for high DHW demands. The heat
cell is comprised of the proven stainless steel Inox-Radial heat
exchanger, the modulating MatriX cylinder burner and the automatic
Lambda Pro Control combustion controller.
The integral 46 litre stainless steel loading cylinder offers the same
DHW convenience as a separate 150 litre 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 system com-
ponents 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 (3.2 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.
Recommended applications
■ Detached and terraced houses
■ New build (e.g. pre-fabricated houses and housing association
projects): installation in utility rooms and attics
■ Modernisation: Replacement of system boilers, floorstanding atmos-
pheric gas boilers and oil/gas boilers with DHW cylinders below.
Benefits at a glance
■ Standard seasonal efficiency [to DIN]: up to
98 % (Hs) [gross cv] / 109 % (Hi) [net cv]
■ Durable and efficient thanks to the Inox-Radial heat exchanger
■ Modulating MatriX cylinder burner with a long service life thanks to
stainless steel MatriX gauze – resistant to high temperature loads
■ High DHW convenience: NL (performance factor) up to 1.5 (corre-
sponds to a separate DHW cylinder with approx. 150 litre capacity)
■ Energy-saving high efficiency circulation pump (compliant with
Energy Label A)
■ Easy-to-use Vitotronic control unit with plain text and graphic display
■ The programming unit of the control unit can also be fitted on a wall
mounting base (accessories)
■ Lambda Pro Control combustion controller for all gas types – saves
on costs, with inspection interval extended to 3 years
■ All system components, such as loading cylinder, (heating water)
expansion vessel, pumps and safety valves are fully fitted.

operation
BIntegral diaphragm expansion vessel (Vitodens 300-W, up to
19 kW)
CInox-Radial heat exchangers made from stainless steel - for high
operational reliability, a long service life and high heating output
on a very small footprint

ation
EIntegral, variable speed high efficiency circulation pump
FGas and water connections
GDigital boiler control unit
The top model among the wall mounted gas condensing boilers is the
Vitodens 300-W. The MatriX gas burner and Inox Radial heat
exchanger made of stainless steel are a combination that guarantees
high efficiency and high long-term heating convenience.
All Vitodens 300-W models are now equipped with the automatic
Lambda Pro Control combustion controller. Modulation range up to
1:10 (19 kW).
The integral variable speed high efficiency circulation pump reduces
power consumption by up to 70 %.
The Vitodens 300-W is equipped with integral sensor technology that
enables operation without additional measures to ensure a minimum
flow rate. The integral flow rate sensor allows hydraulic balancing with
minimum effort (eligible for KfW subsidies [in Germany]).
Recommended applications
■ Modernisation of heating systems on single floors or in detached
houses with high demands for central heating and DHW conven-
ience
■ Systems with little space available for the boiler or tight (flexible)
installation locations (e.g. attic or inside furniture)
■ Replacement of existing floorstanding boilers in various systems,
also with several heating circuits and underfloor heating
Benefits at a glance
■ Standard seasonal efficiency [to DIN]: up to 98 % (Hs) [gross cv]/
109 % (Hi) [net cv]
■ Low cycle frequency, even with low heat demand, through optimised
pauses and wider modulation range of up to 1:10 (19 kW)
■ Durable and efficient through the Inox-Radial heat exchanger with
water-cooled front and back panel, plus venting function
■ MatriX gas burner (spherical burner) with Lambda Pro Control com-
bustion controller for permanently high efficiency and clean com-
bustion.
■ Energy-saving high efficiency circulation pump (compliant with
Energy Label A)
■ Easy to operate Vitotronic control unit with plain text and graphic
display, as well as integral wireless and communication interface,
can be operated alternatively via a smartphone app
■ Easy hydraulic connections: no overflow valve required
■ Diffusion-proof expansion vessel with a high-quality butyl diaphragm
■ Set up for automated hydraulic balancing
