What is a powerflush?

A Power flush is a cleansing process which aims to remove deposits of sludge, rust and any other debris from your central heating system.

When Do You Need A Powerflush?

If you carry out regular servicing and maintenance (professional servicing is recommended annually) then a preventative Powerflush should only be necessary every 5-6 years to clear debris and prevent significant blockages from taking hold.

However, this will vary depending on the system you have. For example, some boilers use copper heat exchangers rather than stainless steel which will corrode quicker.

Signs You Need a Powerflush

There are signs to look out for that suggest that all is not well in your central heating system.

• Cold areas on radiators e.g. at the bottom
• Excessive noise from the boiler or the heating system pump
• Discoloured water when you bleed the radiators
• Heating is slow to warm up
• Cloudy tap water (limescale in the system)
• Some radiators struggle to heat up as well as others
• Radiators cold but pipes are hot
• Boiler regularly shuts down and needs restarting
• No water escapes when you bleed a radiator
• Noisy radiators and or / boiler
• Small leaks in radiators.

If your system is showing any of the signs above, get in touch and we will advise the best way forward.
