VITODENS 200-W SYSTEM
The Vitodens 200-W is loaded with
features and functions to make installation,
fault-finding and servicing easy.
MatriX cylinder burner
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
Integral Grundfos AquaBloc hydraulic unit
For easy service and maintenance
Lambda Pro Control combustion controller
No nozzle change when converting to LPG
Consistently high efficiency even
with fluctuating gas composition and
air pressure
Constantly clean combustion
Low combustion noise through low
fan speed
Optimised efficiency throughout its life
Simple & failsafe commissioning of
the boiler
Dynamic burner cycling
Adjusts the burner firing duration according
to the seasonal heating requirements to
ensure the burner burns for longer and
less frequently, to increase efficiency and
reduce operational wear and tear, e.g.
during Spring and Autumn when heating
requirement is reduced
Take advantage of these benefits
Low energy heating circuit pump
(2 speed) and integrated diverter valve
(for the connection of a DHW cylinder)
Optional high efficiency A rated
modulating pump
For natural gas and LPG (the conversion
to LPG is made at the gas valve – a
conversion kit is not required)
Permissible boiler operating pressure 3 bar
SEDBUK (2005) seasonal efficiency 90.7%
Wide modulation ratio of 1:4, e.g. 6.5 kW
to 26 kW, ensures optimised burner
operation
10 litre expansion vessel
Can be electronically interlocked
with Vitosolic controller for optimum
solar efficiency
Easy installation
Fully assembled and wired
Comes with pre-plumbing jig as standard
Installation with a Vitocell 200 or 300
cylinder meets G3 Building Regulations
without the need for an energy cut-off
valve and cylinder overheat thermostat;
these are now built into the boiler.
Instead a DHW temperature sensor (sensor
part no. 7179114) fitted to the cylinder takes
over the hot water control
Optional sub-mounted mixer kit ideal for
UFH installations or lower temperature
heating circuits (only in conjunction with
Vitotronic 200)
Output range
Boilers within the range offer the following
outputs of 19 kW, 26 kW, 30 kW, 35 kW
There are higher output models available
where there is a higher heat demand or
for commercial applications, with outputs
of 45 kW, 60 kW, 80 kW, 105 kW. These
units can be cascaded to provide a total
output up to 420 kW
Award winning control unit
The Vitodens 200-W is available* with either
a Vitotronic 100 HC2A constant temperature
controller or the Vitotronic 200 HO1B
weather compensation controller, both
controls have a 7 day programmer
*Must be ordered separately
Wall mounted gas fired condensing system boiler, with modulating MatriX cylinder
burner and Inox-Radial heat exchanger, for open and balanced flue operation.
Vitotronic 200 HO1B
