Remove years of sludge, rust and debris from your central heating system – dramatically improving efficiency and extending boiler life.
Over time, central heating systems accumulate sludge (magnetite), limescale and rust that clog radiators, pipework and the boiler's heat exchanger. This reduces efficiency, increases energy bills and can lead to costly breakdowns.
Power flushing forces a high-velocity, low-pressure flow of water and specialised chemicals through your system to dislodge and expel this debris. The result is a system that heats up faster, uses less energy and lasts significantly longer.
We assess your system's condition and take a water sample to confirm the extent of contamination.
Our professional power flush machine is connected to your system via the pump head or a radiator.
High-velocity water and chemical cleanser are circulated through each radiator and pipework in turn.
On completion, a corrosion inhibitor is added to protect the system and prevent future sludge buildup.
The typical cost of a power flush is around £300 - £600, depending on the number of radiators in your home and the severity of the sludge build-up.
We'll always assess your system first and confirm the exact price before starting any work, so you know what to expect.
If you notice any of these signs, your heating system likely has a sludge problem.
If the bottom of your radiators are cold but the top is warm, sludge has settled and is blocking circulation.
A system that takes a long time to reach temperature is working harder than it should due to blockages.
Gurgling, banging or kettling sounds from the boiler or heating pump can indicate sludge circulation issues.
Dark, dirty water when you bleed radiators is a clear sign of significant sludge and magnetite buildup.
If your heating costs have crept up without an obvious reason, a dirty system could be to blame.
Sludge around the heat exchanger causes overheating and lockouts. A flush can resolve this without replacing the boiler.
Most power flushes are completed within a day, though larger homes with more radiators may take a little longer.
We take care to protect your floors and furnishings, and the process is carried out with minimal disruption. Your heating will be back up and running the same day.
Most systems don't need flushing every year. It's typically recommended every 5 to 6 years, before a new boiler installation, or as soon as you notice signs of sludge build-up.
Yes, a power flush cleans the system but doesn't replace your annual boiler service, which checks safety and keeps your manufacturer's warranty valid.
