What is power flushing?

Power Flushing of the central heating system is the process of cleaning pipework, radiators and boilers using magnets, high flow speed pumps and chemicals to remove sludge and debris such as iron oxide (rust) and limescale. The build up of this sludge and iron oxide causes blockages and cold radiators plus poor circulation of heat around the home.

Boiler protection and improved efficiency

The removal of this material improves the heat output of the radiators and boiler while also protecting the boiler from blockages which can cause costly repairs to the heat exchanger inside the boiler.

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.

Signs your system needs a Powerflush

There are a number of signs that could help you determine whether your system needs a Powerflush. These include:

  • Cold spots on your radiators, particularly at the bottom
  • The radiators require constant bleeding
  • Noisy radiators and boiler
  • Radiator leaks
  • Frequent breakdowns
  • Boiler constantly needs to be restarted
  • Central heating takes a long time to heat up
  • Some radiators struggle to heat up more than others
  • Discoloured water when radiators are bled
  • Cold radiators but hot pipes

Who should perform a Powerflush?

You should always ensure that a professional carries out any work on your central heating system. Qualified engineers will always carry their Gas Safe ID with them, you can ask to see it if you have any doubts.

Whilst there are no rules stating that you must be Gas Safe registered to perform a system Powerflush, you must be competent and able to complete the job properly. A mistake could make your heating system perform worse than what it did before and there are risks in using the specialised chemicals. We therefore recommend seeking the help of a professional.
