Everything you need to know about getting a Powerflush in London

How does warm air heating work?

The air is pulled into the home from a vent to the outside. This air is heated over a gas fuelled flame, which is then circulated around the property via a system of ducts. This type of heating is particularly effective in well insulated properties, and in single storey properties like flats and bungalows, but can also be found in larger homes and in commercial properties.

Heating air directly with a flame is very efficient and will rival a gas boiler in terms of efficiency, whilst ducting the air around the home is also very effective, and can heat a room very quickly, as well as help prevent damp and condensation build up around the home.

Why you may need a Powerflush

A Powerflush helps deal with heating problems that you can’t always see.

Reduced efficiency

Sludge, rust and limescale causes leaks and blocked pipes. Dirty water in your pipes causes heating problems and reduces efficiency.


Radiator cold spots

Sludge build-up causes cold spots in your radiators. This means they have to work harder to heat a room and you waste more energy.

Boiler breakdowns

A clogged boiler and pump causes breakdowns. 87% of boiler breakdowns are due to dirty water in your heating system.

When is a powerflush needed?

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.

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 it’s time for 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
  • Noisy radiators and or / boiler
  • Small leaks in radiators.

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. If that’s the case, you’ll need to consult with at least two professionals to make sure you’re getting the right solution at the best price.

Benefits of a powerflush

It’s not all doom and gloom; there are lots of positive reasons to get a Powerflush carried out too.

  • Radiators will heat up quicker
  • Radiators will get hotter
  • Quieter radiators / boiler
  • More energy efficient system = cheaper energy bills
  • Higher hot water temperatures
  • More reliable i.e. less chance of breakdown
  • Increase the life of your heating system.

Is a powerflush always the solution?

In some particularly severe cases you may find that it’s actually more cost effective to replace the system than carry out a Powerflush. A Powerflush will not fix broken parts. If a blockage has caused a part to break that will add time and cost to the job to get the system back to optimum performance. A professional will be able to advise you if this is the case.
