    About This Service

    Over time, central heating systems accumulate a black, mud-like substance called magnetite (sludge), along with rust and limescale deposits. This reduces efficiency, creates cold spots on radiators, and is the leading cause of premature boiler breakdowns. Powerflushing is a highly effective cleaning process that removes these deposits and restores your system.

    Using specialist high-velocity pumping equipment, we flush water and advanced cleaning chemicals through your heating system. This dislodges and removes all the accumulated debris from the boiler, radiators, and pipework, leaving your system working like new.

    Signs that your system desperately needs a powerflush include cold spots at the bottom of radiators, slow system warm-up times, a noisy boiler, dirty black water when bleeding radiators, and frequent pump failures.

    After the powerflush, we dose the system with a premium corrosion inhibitor to protect against future buildup. We also highly recommend installing a magnetic system filter to provide long-lasting protection and maintain efficiency for years to come.

    Common Problems We Fix

    Cold Spots on Radiators

    Heavy iron oxide sludge settles at the bottom of radiators, preventing hot water from circulating. A powerflush removes this completely.

    Noisy Boiler (Kettling)

    Sludge and scale insulate the heat exchanger, causing water to boil locally and make loud banging noises.

    Repeated Pump Failures

    Abrasive sludge destroys the bearings inside central heating pumps. Flushing the system prevents you from having to replace the pump annually.

    High Heating Bills

    A sludged system has to work much harder and longer to heat your home, drastically increasing your gas consumption.

    What To Do If Your System is Sludged Up

    If your radiators are cold at the bottom or your boiler is making loud banging noises, do not ignore it. The sludge is putting immense strain on your boiler's pump and heat exchanger. Continuing to run the system will likely result in a costly Boiler Repair.

    Contact us to arrange a system assessment. We can take a water sample and test the level of contamination before recommending a full powerflush or a chemical clean.
