Power Flushing Services London | Central Heating System Cleaning

Power flushing is a cleaning process that removes sludge, rust, and debris from your central heating system. Over time, these contaminants build up in radiators and pipework, causing cold spots, noisy boilers, and reduced efficiency.

Our professional power flushing equipment uses high-velocity water flow and cleaning chemicals to dislodge and flush out these deposits, restoring your heating system to peak performance.

Radiators with cold spots at the bottom
Some radiators not heating up at all
Boiler making loud banging or kettling noises

Our Power Flushing Process

When we power flush your central heating system, we follow a thorough process:

System Assessment: We inspect your system and test water quality
Connection: Connect our professional power flushing machine to your system
Cleaning: Circulate cleaning chemicals and high-velocity water through each radiator
Flushing: Flush out all contaminants until water runs completely clear
Protection: Add corrosion inhibitor to prevent future sludge buildup
Testing: Check all radiators heat evenly and system pressure is correct

Essential for New Boiler Installations

When installing a new boiler, power flushing your system is crucial. Most boiler manufacturers require a clean system to validate their warranty. Fitting a new boiler to a dirty system is like putting a new engine in a car with dirty oil – it won't last.

We strongly recommend power flushing before any new boiler installation to protect your investment.
