How Often Should I Powerflush the Central Heating System?

As one of the best things you can do for your central heating system, powerflushing is something many people arrange so they can enjoy improved heat and efficiency in their home. 

Over the years, your boiler, pipes and radiators create a build-up of sludge, debris and rust, and all of these things affect how efficiently your central heating system works. They can even eventually contribute to it breaking down.

Powerflushing is a great solution to this, as it involves a thorough, deep clean of your heating system and is undertaken by a Gas Safe registered engineer. Being Gas Safe registered means they have the qualifications and experience to carry out work on heating systems precisely and safely.

But how often should you have a powerflush carried out?

How often does my heating system need powerflushing?

Powerflushing is done by injecting and pumping water at an extremely high velocity through your whole central heating system to dislodge and remove all of the sludge and debris, no matter how stubborn.

It usually only needs doing around every five to six years, but if you don’t know when it was last carried out in your home, ask advice from your Gas Safe registered engineer.

Your system may benefit from a powerflush if there are cold spots on radiators or they are slow to heat up, if you notice any dark sludge-like liquid anywhere in your system or if a magnet sticks to the copper pipework connected to the boiler.
