Power Flushing Services by

the experts

Get your heating system back to full power with a professional flush from HARNCE.

Our qualified engineers will be with you quickly, work efficiently and make sure that your heating is up and running efficiently.

What Is Power Flushing?

Over time, central heating systems can suffer from sludge, limescale, and corrosion debris building up in your pipework, radiators and boiler. This can lead to poor heat output, cold spots, blocked components, and even breakdowns.


Power flushing is a deep-clean process that uses a specialist machine and chemical solution to remove that sludge — restoring flow, efficiency and system reliability.


At HARNCE, we carry out professional power flushing across Lichfield, Burntwood, Rugeley, Tamworth, Cannock and surrounding areas, using high-quality equipment and industry-approved techniques.

Rated by local homeowners and businesses

Signs You Might Need a Power Flush

🔸Radiators cold at the bottom or patchy heat

🔸System slow to heat up

🔸Noisy boiler or pipework (kettling, gurgling)

🔸Frequent boiler lockouts or pressure drops

🔸Dirty or black water when bleeding radiators

🔸Some radiators not working
🔸Reduced flow or uneven heataround the property

“We had issues with cold radiators and constant boiler lockouts, and another company recommended replacing half the system. HARNCE suggested a power flush instead, and it made a huge difference. The engineer was professional, explained everything clearly, and showed us the sludge they removed — it was grim! The heating now works perfectly, and we saved a fortune. We’ve also joined their Members Club for ongoing support.”


— Mr. & Mrs. Bradley, Alrewas
