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
Easy installation
Fully assembled and wired
Comes with pre-plumbing jig as standard
Output range
Boilers within the range offer the following

and integrated diverter valve
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 90.6%
Wide modulation ratio of 1:4, e.g. 6.5 kW to
26 kW, ensures optimised
burner operation
10 litre expansion vessel
High DHW flow rate of up to 14 l/min
(@ 35°C rise)
Integral auto by-pass
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
Navigation is as easy as can be and
mirrors the well known scroll wheel you
are familiar with from mobile phones or TV
remote controls
Features a multi-line plain text display with
large fonts
Display is 70% larger than those of
comparable devices, can show graphics
and is also back-lit
The Vitotronic 200 HO1B, used with
an outdoor sensor, can control up to 3
heating circuits, 2 mixed and 1 unmixed,
e.g. underfloor heating and radiators would
be run off the mixed circuit and a towel rail
would run off an unmixed circuit and a
separate DHW Circuit
