Power Flushing in Kingston
Sludge and rust build up naturally inside central heating systems over the years, causing cold radiators, noisy boilers, poor circulation and premature component failure. A professional power flush removes that debris and restores your system's performance.

Common problems we fix

Pricing
Power flushing is priced as a fixed cost based on the number of radiators, agreed before we start. Adding a magnetic filter at the same time is discounted, as the system is already drained.

Power Flushing — FAQs
How long does a power flush take?
Most flushes take between four and eight hours depending on system size and how heavily sludged it is. Badly affected systems can take a full day.
Will a power flush fix my cold radiators?
If the cold spots are caused by sludge — which is the most common cause — yes. We check radiator temperatures before and after so you can see the difference.
How often should a system be power flushed?
A well-maintained system with inhibitor and a magnetic filter may only need flushing every 8–10 years. Systems without protection sludge up much faster.
Is power flushing safe for older systems?
Generally yes, though very old or fragile pipework needs a gentler approach. Our engineer will assess your system first and recommend the safest method.
