4.2 Scaling
f
f
Almost every type of water deposits limescale at high tem-
peratures. This settles inside the appliance and affects both
the performance and service life. If a flanged immersion
heater is installed, the heating elements must be descaled
from time to time. A heating contractor who knows the local
water quality will tell you when the next service is due.

f
Check the taps/valves regularly. You can remove limescale
deposits at the tap outlets using commercially available des-
caling agents.
