Boiler power flush in Bath and Radstock

Cold-topped radiators, kettling noises, and murky water when you bleed a rad are all the same thing: iron oxide sludge in the system. A proper power flush shifts it — a top-up bottle of inhibitor won't.

For: Homeowners with cold spots and sludge symptoms

The difference between a chemical flush and a power flush

A chemical flush circulates cleaner in the existing system for a few hours. A power flush uses a dedicated high-flow pump with magnetic filtration on each radiator, one at a time. It's the difference between rinsing a mug and scrubbing it.

What the power flush includes

  • Isolate boiler, connect flush pump and magnetic filter
  • Each radiator individually reverse-flushed
  • Inhibitor dosed and system re-pressurised
  • Permanent inline magnetic filter fitted as standard
  • Before/after water sample photos in your report

Frequently asked

Do I really need one?
If your bleed water is dark or the top of your radiators stay cold, yes. If the water is clean and the rads are even, no — a filter alone is enough.
Will it damage old pipework?
Only if the pipework is already close to failing. On very old microbore we sometimes recommend targeted replacement instead — we'll flag it before starting.
How long does it take?
A full day for a 3-bed. Big houses with lots of radiators can run into a day and a half.
