Outstanding versatility
The Vitodens 100 offers the right solution
for every demand – from multiple venting
options to fuel fl exibility (NG or LP) right out
of the box. Plus, installation, service and
maintenance are designed to be fast and
easy with all pipe connections located at the
bottom and serviceable components easily
accessible from the front. You’ll save time
and money with fast service and
maintenance calls.
Helps you save
Select an easy-to- use room thermostat, or,
for greater control and additional energy
savings, utilize the boiler’s on-board control,
which automatically adjusts the boiler water
to outdoor temperatures. This not only
boosts fuel savings, but also keeps your
home warm and comfortable at all times.
On-demand DHW with optional
CombiPLUS Kit
With the new CombiPLUS Kit add
on-demand domestic hot water (DHW) to
your new Vitodens 100 space heating boiler
and say goodbye to your DHW tank. Enjoy
DHW at the snap of your fi ngers all day
long with an outstanding fl ow rate of up
to 3.6 GPM
the energy-saving on-demand indirect-fi red
design. Slightly bigger than a large shoe box,
the CombiPLUS Kit installs underneath or
beside the boiler and requires only minimal
piping and electrical connections. Featuring
stainless steel heat exchanger, pressure
bypass valve, DHW temperature and fl ow
sensors, 3-speed pump, 3-way diverting
valve, and Low Lead Content Certifi cation
(NSF/ANSI 372), get reliable DHW day
after day.
