Vitodens 100-W P25/P29
6.1 to 29 kW
The gas fired condensing boilers Vitodens
100-W P25/P29 offer high heating and DHW
comfort at a good price/performance ratio.
The gas fired condensing boiler is suitable
for installation in any home where there is
limited space. The Vitodens 100-W is ideal
for a flat or small family home. It can easily be
sited in an alcove in the bathroom, kitchen or
utility room.
When it comes to the economy and durability
of a heating system nothing is better than
stainless steel. For this reason the Vitodens
100-W is equipped with the Inox-Radial
stainless steel heat exchanger, which provides
the required reliability and the guarantee of a
long life for the condensing boiler.
Up to 97 percent efficiency
The Vitodens 100-W consumes less energy
because it uses the additional heat from the
exhaust gases. The result is an efficiency of
up to 97 percent. This will reduce your heating
costs and be good for the environment.
Robust burner with long term efficiency
The MatriX cylinder burner developed
and produced by Viessmann ensures high
efficiency because of its stainless steel
MatriX mesh that results in hundreds of tiny
flames rather than one large one, which
ensures Nitrogen Oxide production is kept
to a minimum.
Comfort control with integrated
diagnostic system
The Vitodens 100-W is supplied with
a Vitotronic control unit, featuring a
built-in diagnostics system and frost
protection. When connected to an outdoor
temperature sensor the boiler switches
automatically to the weather compensation
mode, for additional gas savings of up to
12%. The dials are easy to operate and
enable fast adjustment of the heating and
DHW temperature.
Extremely easy to maintain and service
Maintenance and service time of this gas
fired condensing boiler is minimal due to all
components being easily accessible from
the front. All components such as hot water
expansion vessel, pumps and safety valves
are already installed ex works.
