allows for the hard powerflushing of a central heating system with
minimal dismantling. Powerflushing 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 flow problems.
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.
