Oil Heating Technology
VITOROND®100
Gas Condensing Technology
Oil is a precious and indispensable natural resource. As such, oil heating must be economical, efficient, and environmentally friendly. Modern oil heating technology from Viessmann satisfies these demands to deliver maximum performance and comfort year after year.
Efficient by design
The Vitorond 100, with its triple-pass heat exchanger, is designed to achieve
a high level of efficiency while providing exceptional comfort. Unlike single-
pass boilers, the Vitorond 100 guides flue gasses through the heat exchanger
three times (see diagram on next page), allowing the greatest amount of heat
extraction to be achieved. This design significantly increases the efficiency of
the boiler and results in excellent fuel utilization, reducing emissions and
your heating cost.
Control your comfort
For greater heating system control and additional energy savings, choose a
Vitotronic system option. The Vitorond 100 boiler control adjusts the boiler
water to outdoor temperatures, boosting efficiency 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 retrofit 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 flexibility. The full-swing left- or right-hinged
combustion chamber door and easy-to-clean flue gas passageways make service and
maintenance fast and trouble-free.
It doesn’t stop there
Our extensive product portfolio lets you take efficiency 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.

Triple-pass cast iron heat exchanger
Designed for efficiency
The triple-pass design extracts the maximum amount of heat, getting the most from your fuel dollar!
- Pass 1: The burner fires into the stainless steel combustion chamber, sending flue gas to the back of the heat exchanger.
- Pass 2: The flue gasses pass again through the heat exchanger toward the front of the boiler.
- Pass 3: Finally, flue gasses pass through the heat exchanger to the vent at the back of the boiler.
