Power flushing
Power Flushing (MagnaClean System)
Get a quote for a power flush to clear sludge from your central heating system.
Signs you may need one
- Banging or kettling noises
- Lukewarm radiators or hot water
- Leaks or dropping boiler pressure
- Constant thermostat adjusting

Why it matters
Corrosion inside radiators, pipes and joints creates sludge that blocks water flow, reduces efficiency and pushes up energy bills. Filters catch loose debris, but only a chemical flush removes sludge and rust that's settled into the pipework and radiators.
A clean system can let radiators produce up to 47% more heat for the same energy use — and it protects new boilers, since 60% of first-year boiler breakdowns are caused by sludge. Fitting a new boiler on top of a dirty system just means the sludge damages it too.
