Powerflushing
Bring a tired heating system back to life
Radiators cold at the bottom, a boiler that kettles and bangs, heating that takes an age to warm up: classic signs of sludge. A powerflush clears it out, restores circulation, and a magnetic filter keeps it from coming back.
What we can do for you
The different jobs we take on under powerflushing, with straight answers to the questions we get asked most.
Full system powerflush
A professional flush clears the sludge, rusty water and debris that settles out of an unprotected system, the single most common reason radiators develop cold patches and boilers cut out.
- Full system flush with a professional flushing rig
- Chemical treatment and fresh inhibitor dosing
- Radiator-by-radiator temperature check before and after
- Typically improves heat-up times and can cut gas use
Magnetic filter fitting
A magnetic filter fitted after the flush captures circulating debris and keeps the system clean, so the cold spots and boiler noise don’t creep back.
- Magnetic system filter fitted after the flush
- Captures circulating debris before it settles
- Keeps the system clean for the long term

Putting a new boiler onto an older system? A flush protects the new boiler from existing sludge and is often required to keep its warranty intact.
