If sludge and debris is not removed from heating systems, it can build up in radiators, pipework and heat exchangers, causing severe blockages.  This limits the transfer of heat and can result in pipework blockages, radiator valve failure and in some cases this will eventually lead to the failure of the your boiler and may effect the warranty.

Powerflushing is a popular method of cleaning and maintaining a central heating system.
​
A powerflushing unit sends water at high velocity through the system to dislodge and remove debris, limescale, and sludge build-up. A thorough powerflush will improve heat distribution throughout the property, subsequently lowering household energy bills and increasing system reliability.
