A power flush is a process carried out by central heating engineers designed to remove sludge build-up in the boiler, pipes and radiators that make up your central heating system. A power flushing unit sends water through your central-heating system at high velocity to dislodge any build-up of sludge, rust and other debris.This helps to improve the efficiency and lifespan of the boiler and central heating system and prevent breakdowns. As with so many plumbing issues, regular maintenance (including power flushing) is the best way to keep your system in shape. 

The power flushing process has several stages and your engineer will probably take between several hours to the whole day to complete the power flush.

A powerflush can be a good idea, if you're having a new boiler installed but have an old central heating system with old-style radiators. Your boiler engineer can carry out visual and chemical checks which indicate the PH balance and levels of corrosive elements in the system. These will determine whether a full powerflush is needed. Sometimes a ‘dynamic flush’, using clean mains pressure water, is all that's needed. It is a requirement with every new boiler installation that the system is thoroughly flushed, although not necessarily ‘powerflushed’

A suitably qualified central heating engineer should carry out power flushing. This is not something to attempt yourself, particularly if your engineer also needs to open up your boiler or examine other faults in your central-heating system.
