Power Flushing
Power Flushing
Black sludge wrecks boilers and kills radiator efficiency. Our power flush restores full system flow in a single day.
Power Flushing in North London, done properly the first time
Over time, magnetite sludge builds up in central heating systems, clogging radiators, eroding pump impellers and shortening boiler life dramatically.
A power flush uses a high-flow pump and specialist chemicals to clear the system completely. It's required on most new boiler installs and is a smart investment on systems over 8 years old.
