Power Flushing

Is your central heating system under-performing?



If your radiators don’t heat up evenly, or your central heating system makes strange noises, you may well benefit from a professional power flushing service.

The build up of sludge and corrosion deposits in central heating systems is inevitable and over a period of time, these deposits can cause water circulation problems, leading to poorly performing radiators, noisy boilers and excessive heating bills.

Power flushing removes these deposits and the problems that they cause.  This is achieved by passing water through your heating system at high speed but at low pressure, so that no damage is caused to your heating system.  Power flushing will improve circulation and thereby the efficiency of the entire heating system, which in turn will prolong the life of your boiler and reduce your heating bills.

We use the latest technologies to perform power flushing efficiently and thoroughly.

When Do You Need A Powerflush?

If you carry out regular servicing and maintenance (annual servicing by a Gassafe engineer) 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.

IMPORTANT: If you are planning to replace your boiler it’s important that the engineer performs a Powerflush before the installation. Otherwise, you risk contaminating the new boiler with damaging sludge and debris that’s hanging around in the old pipework.

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 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

  • Small leaks from radiator valves

If any of these problems sound familiar to you, it’s time to contact a professional engineer. While a Powerflush may be all that is required to get your heating back on track, unfortunately it’s not always that simple. A system may be so damaged that it is actually cheaper to replace rather than repair.
