Everything you need to know about a powerflush

Over time your central heating system will accumulate large amounts of sludge, rust, and debris. This is unavoidable, but it means that regular maintenance is required as leaving it can affect the efficiency of the heating system. A Powerflush helps deal with heating problems that are not always visible.

Everything you need to know about a powerflush

If you are experiencing issues with your central heating system, you may want to ask yourself these questions.

Do I need a powerflush?

Professional servicing is recommended annually - if you sit in this category, you will only need a preventative powerflush, and this is only required every 5-6 years. It is important to know that this timeline varies depending on the central heating system you have.

Boilers with copper heat exchangers will corrode quicker than the more efficient stainless steel.

You may need a powerflush if:

  • You are experiencing small leaks
  • The radiators are noisy
  • Cold areas on the radiator (particularly at the bottom)
  • Prolonged noise from the boiler
  • Heating is slow to warm up
  • Radiators are cold but the pipes are hot

Besides the obvious benefits of having fully functional radiators and a nice warm home, the main benefits of a power flush include a more efficient system, therefore, your home will warm up quicker.

How does a powerflush work?

The powerflush will typically take anywhere from 6-10 hours depending on the number of radiators in your home. A certified engineer will connect each radiator up to a pump, and this will push specialist chemicals through the pipes, boiler, and radiators.

The chemicals work to remove limescale and corrosion and prevent future rust from forming. The engineer will collect and dispose of any contaminated water or debris that has been removed from the system.

How do I avoid the need for a powerflush?

A major powerflush can be prolonged for many years with regular maintenance. If you have boiler cover, your provider should offer annual inspections, where they perform various comprehensive tests and checks to keep your system in top condition. This means you will only need a preventative powerflush every 5-6 years.

How much does a powerflush cost?

The price of a powerflush will depend on the size and complexity of the heating system. However, a typical powerflush can cost up to £1,000+ with some additional costs for extra chemicals if required.
