Vitodens 333
The Vitodens 333 compact boiler
combines the benefits of the Vitodens 300
condensing boiler with those of a
powerful DHW storage cylinder offering a
capacity of 86 litres.
Innovative heating technology with an
Inox Radial heat exchanger and a
MatriX compact burner plus compact
modular design safeguard high DHW
convenience, which is generally only
available with DHW cylinders which are
twice as large.
The dimensions of the Vitodens 333 have
been matched to common patterns of
kitchen and furniture makers, thereby
enabling easy integration in living spaces.
A height of just under 140 cm enables easy
installation under the eaves and in niches.
All electrical connections are easily
accessible, whilst all hydraulic
components are pre-assembled into a
single unit. This allows the rapid
installation of the Vitodens 333. The new
Vitotronic control unit has been located at
the top of the boiler. This not only makes
operating the boiler easier, but is also
beneficial for service and maintenance.
Benefits at a glance
H Compact dimensions and low height
ensure flexibility in selecting the
installation location (e.g. in attics or
long pane rooms).
H Standard efficiency: up to 109 %.
H Vitotronic control units for room
temperature-dependent or
weather-compensated mode, with
integral diagnostic system and Optolink
laptop interface; capable of
communicating with Vitodata.
VITODENS
The MatriX compact gas burner ensures
environmentally responsible operation
with extremely clean combustion.
Together with the stainless steel heat
exchanger and the DHW storage cylinder
it also ensures that DHW at the required
temperature is always available in large
quantities and at a constant temperature.
An electronic loading control safeguards
the utilisation of condensing technology
over the entire DHW heating process.
H Particularly easy to install, maintain and
service, due to its modular design and
generous wiring chamber.
H Space saving, because clearances at the
boiler sides are no longer required.
H Extremely clean combustion performs
significantly better than the limits set
for the "Blue Angel" certificate of
environmental excellence.
