1.1 Product description
AStainless steel Inox-Radial heat exchangers for high operational
reliability, a long service life and high heating output on a very
small footprint
BModulating MatriX cylinder burner with intelligent Lambda Pro
Control combustion controller for clean combustion and quiet
operation
CIntegral diaphragm expansion vessel
DDigital boiler control unit
EIntegral, variable speed high efficiency circulation pump
FDHW loading cylinder
The Vitodens 222-F gas condensing storage combi boiler is designed
specifically for heating system modernisation projects and as a
replacement for older gas boilers with cylinders installed below. With
an output of up to 35 kW, this heating centre is designed for high DHW
convenience.
The integral loading cylinder with 100 l capacity (up to 26 kW) or
130 l capacity (35 kW) offers the DHW convenience of a separate
DHW cylinder with approximately twice that volume.
As with all Viessmann storage combi boilers, the Vitodens 222-F gas
condensing boiler requires very little space: Width and depth corre-
spond to standard kitchen unit dimensions. The proven MatriX cylinder
burner has a large modulation range of up to 1:7 (35 kW). In conjunc-
tion with the Lambda Pro Control combustion controller the burner
automatically adjusts itself to varying gas qualities and ensures a con-
stantly high standard seasonal efficiency [to DIN] of 98 % (Hs) [gross
cv].
Recommended applications
■ Installation in detached and terraced houses
■ New build (e.g. pre-fabricated houses and housing association
projects): Installation in utility rooms and attics
■ Modernisation: Replacement of gas system boilers, floorstanding
atmospheric 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 through enamelled loading cylinder with
100 l capacity (35 kW: 130 l 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
■ Universal connection sets for individualised installation flush against
the wall
■ No lateral service clearance required
■ Assembly kit (accessories) with the dimensions and design of the
appliance, for the connection of one regulated and one unregulated
heating circuit

Variable speed heating circuit pump in the Vitodens 222-F
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 min. and max. speed and the speed in reduced mode can be
adjusted at the control unit on the existing heating system by using
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:

Variable speed heating circuit pump in the Vitodens 222-F
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 min. and max. speed and the speed in reduced mode can be
adjusted at the control unit on the existing heating system by using
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:

3.1 Product description
AStainless steel Inox-Radial heat exchangers for high operational
reliability, a long service life and high heating output on a very
small footprint
BModulating MatriX gas burner for extremely clean combustion
CIntegral diaphragm expansion vessel
DDigital boiler control unit
EIntegral solar circuit pump
FDual mode DHW cylinder
The Vitodens 242-F gas condensing storage combi boiler for installa-
tion up against the wall is affordable, compact, efficient and solar-
compatible. This storage combi boiler is factory-prepared for the direct
connection of a solar thermal system. The solar control module is
already integrated and is regulated via the Vitotronic control unit.
The 170 l dual mode DHW cylinder provides a high level of DHW con-
venience. For ease of handling the Vitodens 242-F can be transported
in two parts.
