Does my central heating system need a Power Flush?

If your central heating system has any of the following symptoms, it probably needs a POWER FLUSH:

    • Radiator water is dirty
    • System is slow to heat up
    • Radiators need frequent bleeding
    • Boiler failure or lockout
    • Boiler noise
    • Pump failure
    • Pump noise
    • Some radiators are partially or completely cold
    • Blocked radiators
    • Pinhole leaks from radiators

    These problems are a result of inertial corrosion scale and sludge forming within your central heating system. Power Flushing is the only way to give your system a new lease of life and is by far the cheapest option in the long run.

    What happens during a Powerflush and how long could it take?

    Using a specialised machine, a chemical is circulated through your radiators, pipes and boiler at a high pressure. This flushes out any potentially inhibiting deposits and thus allows water to flow freely throughout your system.

    The length of time needed for a Powerflush typically depends on your system’s size and condition. Usually, a Powerflush can take up to around 8 hours to perform, however on particularly complicated systems, it could take up to 2 days.

    What are the benefits of getting a Powerflush?

    There are plenty of benefits of getting a Powerflush. These include:

    • Enhanced energy-efficiency
    • Improved system reliability
    • Potentially lower energy bills*
    • Reduced likeliness of boiler breakdown
    • Could increase system lifespan
    • Radiators can warm up quicker
    • Better quality of heating and hot water
    • Reduced noise from boiler and radiators

    When should you get a system Powerflush?

    Powerflushing is required when the system is heavily contaminated. This can be caused by a number of factors including incorrect installation, the system not been thoroughly cleansed before installation or bacterial growth.

    If you’re getting a new boiler installed, the building regulations recommend that a suitable cleanse is carried out prior to the installation. This can vary from a simple system flush with clean water to a powerful Powerflush on more contaminated systems. This helps to prevent your new system from being contaminated and inhibited by the sludge and debris that was present in your old one.
