Power flushing is carried out by our Gas Safe registered engineers and we use the best power flushing machines to ensure the best results.

What exactly is a Powerflush?

A Powerflush is a cleaning process carried out by our heating engineers for your central heating which removes dirt, rust, sludge and any other debris that may have built up within your system (radiators, pipes, boiler etc) over time. 

Our heating engineers use a Proflush Professional Magmaster power flushing unit to send water through your system at very high speeds to dislodge any unnecessary build-up of debris.

We only use the best power flushing unit available supplied by Norstrom. To read more about the Proflush Professional Magmaster we utilise click here.
