8.1.1 Oxygen diffusion
Material losses
!
Avoid open heating systems and plastic pipes in under-
floor heating systems which 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 heating elements or steel pipes).
Material losses
!
The products of corrosion (e.g. rusty sludge) can settle in
the heating system components and can result in a lower
output or fault shutdowns due to reduced cross-sections.
Material losses
!
Avoid open vented solar thermal systems and plastic
pipes which are permeable to oxygen.
With plastic pipes that are permeable to oxygen, oxygen diffusion
may lead to corrosion on the steel components of the solar thermal
system (e.g. on the indirect coil of the DHW cylinder).
8.1.2 Water quality, solar circuit
A glycol/water mixture of up to 60 % is permitted for the indirect
coil in the solar circuit if only dezincification-resistant metals,
glycol-resistant gaskets and diaphragm expansion vessels suitable
for glycol are used throughout the installation.
8.2

Decommissioning

If the heating system is not in operation and the installation
location is not protected against frost, drain the appliance and
connected system. This is relevant where there is a risk of frost.
9.

Maintenance

No special maintenance is required for the appliance. A regular
visual check is sufficient.
