Patented technology, manufactured
by Viessmann
Low emissions
Long service life through stainless steel
MatriX gauze
Optimum matching of heat exchanger
and burner
Inox-Radial heat exchanger
Self-cleaning smooth stainless steel surface
Same flow direction for flue gas
and condensate
Highly corrosion resistant through
high-grade stainless steel (type SS 1.4571)
10 year warranty against corrosion
Durable and efficient through the stainless
steel Inox-Radial heat exchanger
MatriX cylinder burner with Lambda Pro
combustion control for permanent high
efficiency and clean combustion
Take advantage of these benefits
Two cylinder sizes, 100 litres and 130 litres
for best hot water performance
DHW expansion vessel and DHW
circulation pump can be integrated inside
the appliance
Dynamic burner cycling reduces the number
of burner starts over the year by a third
SEDBUK (2005) seasonal efficiency 91%
Wide modulation ratio of 1:4, e.g.
6.5 kW to 26 kW, ensures optimised
burner operation
For natural gas and LPG (conversion
is made on valve settings and
controller coding)
Includes unvented safety kit and DHW
expansion vessel
Standard top connection set*
Standard RH or LH side connection set*
Easy installation
Optional connection set for top level
(7348566) or side pipe installation (7350854)
No side clearance required, boiler stands
flush to the wall
Optional built-in hot water circulation
pump for secondary turn circuit (Part No.
7351819 DHW Secondary Circuit kit)
CH output range
Boilers within the range offer the following
DHW outputs of 19 kW, 26 kW, 35 kW
Flow rates are up to 20 l/min
On the 35 kW model a 10 minute peak
flow performance provides 200 litres of
60°C hot water which is equivalent to
a larger cylinder
Award winning control unit
The Vitodens 222-F is available*
with either a Vitotronic 100 HC2A
constant temperature controller or the
Vitotronic 200 HO1A weather
compensation controller, both controls
have a 7 day programmer
The control can be sited up to 5 m
away from the boiler enabling installation
in areas with restricted access, e.g. if
the boiler is installed in a garage or loft
Cylinder Loading System (CLS)
Most unvented cylinders use a heating coil
to heat up the cylinder. The CLS technology
replaces the coil with a plate heat exchanger.
A DHW pump circulates the cold water from
the bottom of the cylinder, through the plate
heat exchanger and puts the hot water back
to the top of the cylinder.
*Must be ordered separately
