A powerflush is simply a process that gives your central heating system a thorough internal clean and usually improves your system’s performance, which can lead to lower gas bills.

Powerflushing your system can also extend the lifespan of your boiler. This is required under Part L of the building regulations for any new system.

Once a gas central heating system has undergone a professional powerflush, chemicals are added to the water in the system to prevent further corrosion and to ensure your system runs more efficiently.

New systems and systems we’ve flushed are advised to have a Scalemaster device installed, which collects the debris magnetically as the system is flows. During your annual service this device is cleaned.
