Power Flush in Bournemouth & Poole

A power flush is a professional cleaning process for central heating systems. A high-flow machine pumps chemically treated water through your boiler, pipes and radiators at high velocity to dislodge and remove sludge, rust and magnetite debris. The dirty water is then expelled and replaced with clean water treated with an inhibitor, such as Adey MC1, to prevent future corrosion. We use industry-approved Kamco equipment on every job.

The price depends on the size of your system: from £550+VAT for up to 10 radiators, from £750+VAT for up to 15 radiators, and from £1,000+VAT for 20 radiators and over. That includes the chemicals, a full system clean with specialist equipment, balancing the radiators and checking circulation afterwards. Our pricing page sets out the full list.

A standard power flush takes between 6 and 8 hours for a typical home with 8 to 10 radiators. Larger systems or heavily contaminated heating systems may need a full day or longer. Our engineers complete most power flushes within a single visit, restoring your heating to full efficiency before we leave.

Common signs include cold spots on radiators (especially at the bottom), a noisy boiler or pipes, radiators that are slow to heat up, discoloured water when you bleed them, and rising energy bills. If your boiler frequently breaks down or trips out, sludge build-up is often the cause.

Most central heating systems benefit from a power flush every 5 to 6 years, though systems with magnetic filters and regular inhibitor top-ups may last longer. Older systems or those without protection may need flushing every 3 to 4 years.

When carried out by a qualified engineer, a power flush is safe for the vast majority of heating systems. On very old or corroded pipework, a cautious low-pressure flush may be used instead. Our engineers assess your system before starting and adjust the approach where needed, and all work comes with a full workmanship guarantee.

A power flush uses a specialist machine to force chemically treated water through the system at high velocity, physically dislodging stubborn sludge and debris. A chemical flush — also called a system flush — relies on chemicals alone without the pressurised machine, which makes it less effective on heavily contaminated systems. For most homes in Bournemouth and Poole, a full power flush gives significantly better results.

Yes. A professional power flush should always end with a quality inhibitor added to protect against future corrosion and sludge build-up. We use Adey MC1 Central Heating System Protector, which is compatible with all metals including aluminium and works effectively in the hard water conditions found across Dorset.
