Power Flushing in North London, done properly the first time
Black sludge wrecks boilers and kills radiator output. A proper power flush restores full system flow inside a single day.
About our power flushing service
Magnetite sludge quietly builds up inside central heating systems over the years, clogging radiators, eating pump impellers and dramatically shortening boiler life.
Our power flush uses a high-flow pump and specialist chemicals to strip the system clean. It's required on most new boiler installs and a smart move on any system over about eight years old.
