Powerflushing is to ensure that any dirt and obstacles are removed from the central heating system.

A lack of powerflushing can cause blockages in the system which can cause long term damage to your central heating. These include, but are not limited to, radiator leaks and limiting the system to bad or no flow’

Our powerflushing unit sends high pressurised water flow through your central heating system dislodging debris, rust and dirt. Powerflushing can extend the lifespan of your boiler and central heating system saving you hundreds of pounds in the long-term.

is powerflushing the best solution to fix a boiler and central heating system?

Powerflushing is at its best when applied to a newly installed system and during a regularly scheduled maintenance.

Will powerflushing remove 100% of all the dirt and sludge from your system?

Unfortunately, it won’t remove 100% of the dirt, however it will remove most of it. If your system is old then powerflushing may not be the solution. Instead, you may need a boiler repair instead.

However, Charter Gas’ experienced engineers will tell you the best route forward for your specific heating system and needs after a site visit.
