Vitorond 100, VR1 – 91 to 245 MBH
Oil-fi red technology for clean, effi cient combustion and durability
Oil is a precious and indispensable natural
resource. As such, oil heating must be
economical, effi cient and environmentally
friendly. Modern oil heating technology
from Viessmann satisfi es these demands
to deliver maximum performance and
comfort year after year.
The Vitorond 100 is ENERGY STAR®
qualifi ed. By choosing an ENERGY
®
appliance, you are helping to
STAR
promote cleaner air and a healthier
environment.
Effi cient by design
The Vitorond 100, with its triple-pass heat
exchanger, is designed to achieve a high level
of effi ciency while providing exceptional
comfort. Unlike single-pass boilers, the
Vitorond 100 guides fl ue gasses through the
heat exchanger three times (see diagram on
next page), allowing the greatest amount of
heat extraction to be achieved. This design
signifi cantly increases the effi ciency of the
boiler and results in excellent fuel utilization,
reducing emissions and your heating cost.
Control your comfort
Select an easy-to-use room thermostat or, for
greater control and additional energy savings,
choose a Vitotronic system control. Unlike
conventional boilers, which operate at a
consistently high boiler water temperature, the
Vitorond 100 with Vitotronic control adjusts the
boiler water to outdoor temperatures, boosting
effi ciency while keeping your home
comfortable at all times.

The Vitotronic control even allows for safe,
low-temperature operation by protecting the
heat exchanger against condensation and
potential damage. This means your boiler uses
less fuel, reducing your energy consumption
and heating bill.
Convenience all around
The Vitorond 100 is your ideal choice for an
economical retrofi t of your heating system.
Thanks to its compact, space-saving design,
the Vitorond 100 is easy to install even in
older buildings with narrow entrances and
small mechanical rooms. And with the direct
vent option, the Vitorond 100 (up to VR1-33)
does not require a chimney or combustion air
supply opening for even greater installation
fl exibility. The full-swing left- or right-hinged
combustion chamber door and easy-to-clean
fl ue gas passageways make service and
maintenance fast and trouble-free.
It doesn’t stop there
Our extensive product portfolio lets you take
effi ciency and energy savings a step further.
Reduce your energy costs by integrating hot
water production with your heating boiler, and
manage the entire system with one of our
control solutions. Or put the sun to work
for you by adding a solar thermal package.
With the entire system from one source,
you don’t have to compromise: total system
performance and additional energy savings go
hand-in-hand.
