7.2
Checking and correcting the water pressure
Your heating system must contain sufficient water to
ensure the functionality of your system.
SYSTEM DAMAGE
through frequent re-filling.
CAUTION!
The system may be damaged, depending
on water quality, by corrosion and scaling,
if you frequently need to re-fill your system
with make-up water.
Notify your local heating contractor, if
you regularly need to 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 introduced 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 thereafter at 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.
