A heating surface made of stainless steel
The MatriX burner is a milestone
At the heart of all Vitodens
condensing boilers is a
SA240 316Ti stainless steel,
Viessmann-made Inox-Radial
heat exchanger. A key compo-
nent to outstanding efficiency,
this high-performance heat
exchanger delivers proven
reliability and a long
service life.
The MatriX cylinder burner, in
combination with the Inox-
Radial heat exchanger, ensures
high energy efficiency. Plus,
The MatriX burner’s Lambda
Pro combustion management
system automatically adapts
to changing gas type and
quality for optimal efficiency.
