The Inox-Radial heat exchanger
and how it works
The heat exchanger design
Stainless steel is, without doubt, the best material
for primary heat exchangers in condensing
boilers. One of the unique design features of all
Vitodens boilers is the Inox-Radial heat exchanger
made from high grade stainless steel. Designed
for long-term reliability, high performance and
self cleaning. We are so confident in our heat
exchanger that we guarantee it for 10 years
against corrosion.
Innovative technology and high
quality materials
Stainless steel is used in many demanding
applications including medical technology and
aerospace. When stainless steel is combined
with innovative design there are significant
benefits in durability and reliability.
100% corrosive resistant - one of the many
advantages of stainless steel
Stainless steel is ideally suited to condensing
boilers. It is temperature stable and resistant to
condensate, making it very corrosion resistant
and extremely durable.
Excellent self-cleaning depends on a
smooth surface
The smooth surface of stainless steel is perfect
for condensing boilers. Viessmann builds on this
advantage by designing heating surfaces which
enhance the self-cleaning effect. This means
the condensate drains off more quickly. Dirt
and residues of combustion cannot take hold,
resulting in considerable savings in maintenance,
the certainty of long term high efficiency,
reliability and increased product life.
Maximum energy from minimum space
Small in size, big on performance. Efficient
transfer of the heat from the heating gas to
the water depends on the heating gas being in
extremely close contact with the heating surface.
Viessmann has developed special technologies
for this very purpose, such as the Inox-Radial
heating surface used in wall-mounted boilers.
The Inox-Radial heat exchanger is the result
of intensive development
Heat transfer in the Inox-Radial heat exchanger
takes place across a laminar split flow. Instead of
a round section stainless steel pipe, Viessmann
has developed a rectangular stainless steel
spiral wound heat exchanger. A slot of 0.8mm
is maintained across the total length and this
produces a laminar flow without a boundary layer
- and excellent heat transfer.
In 1995 Viessmann developed
the Inox-Radial stainless
steel heat exchanger. At the
heart of all Vitodens wall-
mounted condensing boilers
is a corrosion-resistant,
high-alloy stainless steel
Inox-Radial heat exchanger. A
key component to outstanding
efficiency, this high
performance heat exchanger
also delivers proven reliability
and a long service life.
