water.
Domestic hot water system requirements
The following materials can be used in the consumer's domestic
hot water system:

corrosion damage. This especially applies to zinc-plated materi-
als and materials containing aluminium. If there is a risk of water
contamination during operation, it may be necessary to install a
filter.
