About This Service
Over time, central heating systems accumulate sludge, rust, and limescale that reduce efficiency, cause cold spots on radiators, and put unnecessary strain on your boiler. A professional power flush uses high-velocity water and specialist chemicals to thoroughly clean the entire system, restoring proper flow and significantly improving performance. NBS Plumbing & Heating uses industry-leading power flushing equipment to clean systems of all sizes.
What's Included
- Removes harmful sludge, rust, and scale

- System inhibitor added for ongoing protection
Frequently Asked Questions
How do I know if I need a power flush?
Signs include radiators that are cold in patches or at the bottom, a noisy boiler, slow system warm-up, or discoloured water when bleeding radiators. If your boiler is being replaced, a power flush beforehand is strongly recommended.
How long does a power flush take?
Most residential systems take 4–8 hours depending on the number of radiators and severity of contamination. We aim to complete the work in a single visit.
Do I need a power flush before a new boiler?
Most boiler manufacturers strongly recommend a system flush before installation to protect the new boiler's warranty. Fitting a new boiler to a contaminated system can void the warranty and cause premature failure.
What happens after the power flush?
We add a corrosion inhibitor to protect the system long-term and fit a magnetic filter to capture any future debris before it reaches the boiler.
