Checking and treating the heating
water/filling and supplementary water
Caution.
Risk of material damage due to poor-qual-
ity heating water
▶
Ensure that the heating water is of suffi-
cient quality.
▶
Before filling or topping up the installation, check the
quality of the heating water.
Checking the quality of the heating water
▶
Remove a little water from the heating circuit.
▶
Check the appearance of the heating water.
▶
If you ascertain that it contains sedimentary materials,
you must desludge the installation.
▶
Use a magnetic rod to check whether it contains mag-
netite (iron oxide).
▶
If you ascertain that it contains magnetite, clean the in-
stallation and apply suitable corrosion-protection meas-
ures, or fit a magnetic filter.
▶
Check the pH value of the removed water at 25 °C.
▶
Ensure that oxygen cannot get into the heating water.
Checking the filling and supplementary water
▶
Before filling the installation, measure the hardness of the
filling and supplementary water.
Treating the filling and supplementary water
▶
Observe all applicable national regulations and technical
standards when treating the filling and supplementary
water.
Applicability:
Germany
▶
In particular, observe VDI directive 2035, sheets 1 and 2.
Provided the national regulations and technical standards
do not stipulate more stringent requirements, the following
applies:
You must treat the heating water in the following cases:
–
If the entire filling and supplementary water quantity dur-
ing the operating life of the system exceeds three times
the nominal volume of the heating installation, or
–
If the guideline values listed in the following table are not
met.

1) Nominal capacity in litres/heating output; in the case of multi-
boiler systems, the smallest single heating output is to be used.
Caution.
The use of unsuitable filling and supple-
mentary water may cause aluminium cor-
rosion and therefore result in leaks.
In contrast to steel, grey cast iron or copper,
for example, aluminium reacts with alkaline
filling and supplementary water to produce
substantial corrosion.
▶
In installations with a buffer cylinder,
only use filling and supplementary water
that has a low salt content and that has
electrical conductivity (at 25 °C) of max.
100
μ
S/cm.
▶
Make sure that the pH value (at 25 °C) is
between 8.2 and 8.5.
▶
Make sure that the oxygen content is be-
low 0.1 mg/l.
