Vitodens 200-W wall mounted condensing boilers up to 150 kW are
especially suitable for installation in apartment buildings and commer-
cial or public buildings. For these, the Vitodens 200-W offers an afford-
able, space-saving solution – either as a single unit up to 150 kW or
as a cascade with up to eight boilers and a heating output up to
900 kW.
The Inox-Radial heat exchanger made from stainless steel offers high
output on a very small footprint. This enables particularly efficient
operation with standard seasonal efficiency [to DIN] up to 98 %
(Hs) [gross cv] / 109 % (Hi) [net cv].
The Vitotronic 300-K cascade control unit regulates up to eight
Vitodens 200-W as a single heating centre. It also automatically
matches the boiler output to the heat demand. This means: Subject to
the prevailing demand, either one boiler modulates or all eight boilers
operate concurrently.
We offer the complete range of matching system components for cre-
ating cascade systems, e.g. control units with up to eight appliances,
fully insulated hydraulic cascades and flue gas headers.
Recommended applications
High heating output from a compact, user friendly wall mounted boiler,
suitable for the following applications:
■ Systems with few, large-demand consumers, e.g. fan heaters in
supermarkets/shopping centres, workshops and industrial prem-
ises, commercial nurseries, garages and DHW heating systems
■ Systems with several heating circuits for underfloor and/or static
radiators in apartment buildings, central heating plants for terraced
houses, office buildings and administration premises – particularly
suitable for attic heating centres
■ Heating of public buildings, such as sports and multi purpose halls,
schools, kindergartens
■ Suitable for installation in basement boiler rooms, on intermediary
floors or in the attic
Benefits at a glance
■ Optional cascade installation with up to eight boilers and up to
900 kW rated heating output
■ 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
■ 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
■ Quiet operation through low fan speed
Delivered condition
Wall mounted gas condensing boiler with Inox-Radial heat exchanger,
modulating MatriX cylinder burner for natural gas and LPG, to DVGW
Code of Practice G260 [Germany], plus wall mounting bracket.

Note
Observe information regarding the use of a low loss header (see
page 47).
If the residual head of the circulation pump available as an accessory
is insufficient to overcome the following system pressure drop values,
install an additional, external circulation pump on site.
In such cases, use a low loss header.

Variable speed high efficiency circulation pump in the heating circuit connection set (accessories)
The highly efficient circulation pump uses significantly less power
compared to conventional pumps.
Matching the pump rate of the circulation pump to the individual system
conditions reduces the power consumption of the heating system.

Layout and function
■ Available with R ¾, R 1 and R 1¼ connections.
■ With heating circuit pump, check valve, ball valves with integral ther-
mometers and 3-way mixer or without mixer.
■ Quick and simple installation due to pre-assembled unit and com-
pact design.
■ All-round thermal insulation shells for low radiation losses.
■ High efficiency pumps and optimised mixer curve ensure low elec-
tricity costs and precise control characteristics.
■ The bypass valve for hydraulic balancing of the heating system is
available as an accessory and is provided as a threaded component
for inserting into the prepared hole in the cast body.
■ Individually wall mounted or with a double or triple manifold.
■ Also available as a kit. For further details see the Viessmann pricel-
ist.
For part numbers in conjunction with the different circulation
pumps, see the Viessmann pricelist.
The dimensions of the heating circuit distributor are the same, with or
without mixer.
