5853906

The top model among the wall mounted gas condensing boilers is
the Vitodens 200-W. The MatriX-Plus gas burner and Inox-Radial
heat exchanger made of stainless steel are a combination that guar-
antees high efficiency and a high level of heating convenience over
the long term.
All sizes of the Vitodens 200-W are equipped with the automatic
Lambda Pro Plus combustion controller. Modulation range down to
1:17 (32 kW).
The integral, variable speed high efficiency circulation pump reduces
power consumption by up to 70 %.
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 heat generator 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
Control unit with 7-inch screen
■ Seasonal central heating energy efficiency ηS up to 94 % (label A).
■ Low cycle frequency, even with low heat demand, through opti-
mised pauses and wide modulation range down to 1:17 (32 kW)
■ Durable and efficient thanks to Inox-Radial stainless steel heat
exchanger
■ MatriX-Plus gas burner with Lambda Pro Plus combustion control-
ler for permanently high efficiency and clean combustion.
■ Power saving, high efficiency circulation pump
■ Colour touchscreen with plain text and graphic display, commis-
sioning assistant, energy consumption indicators and the option of
operation from a mobile device
■ Web-enabled through integral WiFi interface for operation and
service via Viessmann app

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
mode or reduced mode. The control unit transmits the current speed
specifications to the circulation pump via a PWM signal.
The min. and max. speeds and the speed for reduced mode can be
matched to the existing heating system via parameters at the control
unit.
Setting (%) in the heating circuit 1 group:
■ Min. speed: Parameter 1102.0
■ Max. speed: Parameter 1102.1
■ In the delivered condition, the minimum pump rate and the maxi-
mum pump rate are set to the following values:

ered condition in %

■ In conjunction with a low loss header, heating water buffer cylinder

at a constant speed.

to the flow rate at the draw-off point.
If a greater volume of water is required, cold water needs to be
admixed, which reduces the outlet temperature.

The Vitodens 222-W is a particularly space saving, 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-Plus
gas 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 coil. DHW is available immediately and constantly at the
required temperature, even simultaneously at different draw-off
points. In addition to the loading cylinder, all the most important sys-
tem components, such as the heating water expansion vessel,
pumps and safety valves, are integrated and fully fitted. All this –
with a total weight of max. 68 kg and in a casing that fits into a
standard 600 mm wide kitchen unit space.
