Power flushing — bring your radiators back to life.
If radiators are cold at the bottom, take forever to warm up, or your boiler is banging and clunking, sludge is almost certainly the cause. A power flush uses high-flow, low-pressure chemical cleansing to strip years of magnetite from every radiator and pipe run.
MagnaCleanse process
Powerful magnet capture removes iron oxide as it lifts.
Restored heat output
Even radiator temperatures top to bottom, quicker warm-up.
Protects the boiler
Stops sludge blocking the heat exchanger and pump.
Lower bills
A clean system needs less gas to hit the same room temperature.
Signs your system needs a power flush
- Cold spots at the bottom of radiators (hot at top)
- Radiators upstairs work, downstairs don't (or vice versa)
- Boiler kettling, banging or noisy pump
- Black or brown water when you bleed a radiator
- Repeated boiler lockouts or overheating faults
What's included
Up to 8 radiators for £500 (£25 per radiator thereafter), a full chemical cleanse and neutraliser, a fresh dose of inhibitor, and a MagnaClean filter fitted or serviced as part of the visit. All work carried out personally by Stewart Hardy.
