3.7 Information on the operating environment
Limescale deposits (from hard water) and corrosion, as well
as chemical and physical reactions, can cause damage to the
home station.
The selection of material for the plate heat exchanger (copper
or stainless steel) must be checked with reference to the water
quality (corrosion resistance).
The system planner is responsible for evaluating these
parameters and taking appropriate precautions.
