Filling the heating system
Fill water
As a heat transfer medium for DHW heating, the heat-
ing water must meet fluid category ≤ 3. This require-
ment is met if water of potable quality is used as heat-
ing water. For example, if additives are used, the addi-
tive manufacturer 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
above 300 ppm must be softened, e.g. with a
small softening system for heating water.
