Some signs you may need a powerflush

Powerflushing your central heating system can help keep it working efficiently and prevent future problems. Here are some of the key benefits:

    • Saves money on energy bills – By removing debris, a powerflush improves efficiency so your system does not have to work as hard to heat your home. This can lead to lower energy usage and bills.
    • Improves reliability – Sediment buildup can lead to blocked pipes, radiator leaks, and boiler breakdowns. Powerflushing reduces these problems.
    • Extends system lifespan – The high-pressure flush removes corrosion-causing debris. This protects components from damage and extends the operating life.
    • More even heating – With pipes and radiators cleared of sludge, hot water can circulate properly. This means fewer cold spots.
    • Quieter operation – Buildup in pipes and radiators can cause noise. A powerflush removes the debris causing abnormal sounds.

There may be other signs you notice too. Talk to us and we can advise you on whether a powerflush is the right approach to take.

How much does a powerflush cost?

The cost of your powerflush will depend on the time it takes to perform. Eight hours is around average, though it can take longer if you have a large property or your heating system is complex. We’ll be happy to give you a quote.

Before a powerflush:

Built-up sediment within the heating system settles at the bottom of radiators, preventing hot water from circulating evenly. This produces cold spots.


After a powerflush:

Sediment has been removed from the heating system, allowing each radiator to work effectively. The addition of corrosion inhibitors ensures long-lasting results.
