What is a powerflush?
A powerflush is a process designed to remove sludgy build-up from your boiler, pipes and radiators in your central heating system.
Water is sent through your central-heating system at high velocity by a power flushing unit to dislodge any build-up of sludge, rust and other debris that may be present.
Powerflushing helps to improve the efficiency and lifespan of the boiler and central heating system, helping to prevent breakdowns (87% of boiler breakdowns are due to dirty water in the heating systems).
All powerflushes are carried out by our own central heating engineer.
When is a powerflush needed?
One or more of the following symptoms could indicate that your central heating system would benefit from a powerflush;
● Cold radiators and radiators with substantial cold spots
● Black, sludgy water in the heating system
(often indicated during radiator removal or a failed heating pump/valve replacement)
● Poor circulation within a system that used to perform well
● A magnet attaches to copper pipe work (signs of iron sludge within the pipes)
● An overflowing attic header tank (we would also advise checking the pump speed in this instance)
We also recommend a powerflush if installing a new boiler that will be integrated into the existing central heating system with old-style radiators.
Our boiler engineer carries out visual and chemical checks to determine the PH balance and levels of corrosive elements in the system. These results will establish if a full powerflush is necessary. In some cases all that's needed is a 'dynamic flush' using clean mains pressure water.
