If your radiators are cold at the bottom, your boiler sounds like a kettle, or you’ve just had a new boiler installed and you want it to last, power flushing in Maidstone is the fix. We flush the whole system at pressure with proper cleaning chemicals, then add an inhibitor and — usually — a magnetic filter so it stays clean.
When you need a power flush
- Radiators cold at the bottom, hot at the top — classic sludge signature
- Boiler making banging or kettling noises
- Some radiators never get hot even after bleeding
- Black water coming out when you bleed a rad
- Before fitting a new boiler on an old system (protects the warranty)
- After a leak that let air into the system and started corrosion
How our power flush works
We connect a high-flow magnetic flushing rig across your system, isolate the boiler, and cycle water, cleaner and inhibitor through every radiator in turn. Sludge and iron oxide come out into the machine’s filter — often litres of it on an old system. We reverse-flush each radiator, refill with fresh treated water, and reinstate the boiler. A typical 8-radiator house takes most of a day.
What you get afterwards
- Radiators hot top-to-bottom, quicker warm-up, less gas used
- Boiler warranty protection — most manufacturers require a clean system
- Corrosion inhibitor and — if fitted — magnetic filter to keep it clean
- Written report of before/after water clarity
We cover Maidstone town and the surrounding villages — Bearsted, Aylesford, Ditton, East Malling, Loose, Boughton Monchelsea, Barming, Allington, Larkfield and Leybourne. Most power flushing jobs across ME, TN and CT postcodes are quoted the same week and scheduled within a few working days.
Common questions from Maidstone customers
How long does a power flush take?
An 8-radiator family home takes most of a day. Bigger properties or systems with heavy sludge can run into a second day.
Will it fix a noisy boiler?
Kettling and banging noises are almost always sludge or scale. A flush plus a magnetic filter usually clears both.
Does the boiler manufacturer require this?
Most do — a system flush and inhibitor dose is a standard condition of the extended warranty on Worcester, Vaillant and Ideal installs.
