How Often Should You Power Flush Central Heating

This depends on the material your radiators are made out of, the age and type of your boiler, and the hardness of your water. The short and generally agreed upon answer is that you should flush your radiators every 5 to 6 years.

Are power flushes necessary?

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.

How often should you have your radiators flushed?

If there are no other signs that you need to flush out your radiator, you should do it at least every 30,000 miles or according to your owner’s manual recommended schedule.
