Checking and correcting the water pressure

Your heating system must contain sufficient water to
ensure the safe and correct function of your system.
SYSTEM DAMAGE
through frequent re-filling.
CAUTION!
The system may be damaged, depending
on water quality, by corrosion or scaling, if
you frequently need to re-fill your system
with make-up water.
Enquire from your local heating
contractor whether you can use your
public water untreated or whether you
need to treat it before filling your
system.
Notify your local heating contractor if
you need to regularly add make-up
water to your system.
Fill make-up water into your system, if the system
pressure is too low (see Chapter 3 "Using correct fill and
make-up water", page 7).
7.2.1 When do you need to check the water
pressure in your heating system?
– Recently filled in make-up water loses much of its
volume in the first few days because it releases
gases. With new systems therefore check the water
pressure in your heating system initially on a daily
basis, and then after increasing intervals.
USER NOTE
Air pockets may form through the fill or
make-up water releasing gases.
Vent the system via the radiators and, if
required, replenish the system with
make-up water.
– Check the water pressure monthly, if the heating
system still loses volume.
We reserve the right to make any changes due to technical modifications.
