Power Flushing
Expert Power Flushing from Hillingdon Boiler Experts
How It Works
Survey & Flow Check
We inspect the system, test flow and identify cold spots, traps and vulnerable components before connecting the flushing kit.
High-Flow Flushing & Filtration
Our machine circulates treated water with chemical cleaners and magnetic/inline filtration to extract magnetite, sludge and debris safely.
System Neutralise & Report Back
We add inhibitors, run pressure and flow checks, leave a service report and advise on any further work or parts needed.
Why Choose us for Power Flushing?
Improved heat and efficiency
Removes insulating sludge and blockages so radiators heat evenly, the pump runs freer and your boiler works less hard.
Protects boiler and radiators
Magnetic filtration and correct chemical dosing reduce long-term corrosion and lower the risk of repeat breakdowns.
Local, certified engineers you can trust
Gas Safe and CIPHE accredited with 21 years' experience and a 12-month workmanship guarantee for peace of mind.
Professional kit, professional results. We use high-capacity power-flushing machines with controlled chemical dosing, magnetic filters and fine particulate filtration to capture magnetite and sludge before it reaches the boiler. The method suits wet central heating in period houses and modern systems alike — we adjust flow and temperature to protect aluminium radiators, pumps and boiler heat exchangers while complying with manufacturer guidance and Gas Safe/CIPHE best practice.
When you need it. Common signs you need power flushing include cold spots on radiators, frequent air bleeding, noisy pumps or rising energy bills. Typical visits include pre-survey, the high-flow flush, inhibitor dosing and a final performance check.
