9.1.1 Oxygen diffusion
Material losses
!
Avoid open vented heating systems and underfloor
heating systems with plastic pipes that are permeable
to oxygen.
In underfloor heating systems with plastic pipes that are per-
meable to oxygen and in open vented heating systems, oxygen
diffusion may lead to corrosion on the steel components of the
heating system (e.g. on the indirect coil of the DHW cylinder, on
buffer cylinders, steel radiators or steel pipes).
Material losses
!
The products of corrosion (e.g. rusty sludge) can set-
tle in the heating system components, which may re-
sult in a lower output or fault shutdowns due to reduced
cross-sections.
