This allows for the hard flushing of a central heating system with
minimal dismantling. Flushing the system loosens corrosion deposits and
sludge which is then removed from the system leaving pipes and radiators
clear and free for good circulation.
SLUDGE - Cause - Effect
Sludge is a 'mud' resulting
from the reaction between the water in your system and the steel in the
radiators which can build up over a period of time and cause circulation and
The following are some symptoms to watch out for, which may indicate
your central heating system may have a sludge problem:
Some radiators are completely or partially cold
- Radiators need frequent bleeding
- Repeated pump failures/corrosion deposits in pump casing
- Strange and unpleasant noises from the boiler.
