Filling the heating system
Fill water
According to EN 1717 with DIN 1988-100, as a heat
transfer medium for DHW heating, the heating water
must meet fluid category ≤ 3. This requirement is met if
water of potable quality is used as heating water. For
example, if additives are used, the additive manufac-
turer must specify which category the treated heating
water comes under.
!
Please note
Unsuitable fill water increases the level of
deposits and corrosion and may lead to appli-
ance damage.
■
Flush the heating system thoroughly before
filling.
■
Only use fill water of potable water quality.
■
Special antifreeze suitable for heating systems
can be added to the fill water. The antifreeze
manufacturer must verify its suitability.
■
Fill and top-up water with a water hardness in
excess of the following values must be soft-
ened, e.g. with a small softening system for
heating water.
