Power Flushing is a highly effective cleansing operation used for cleaning a central heating system of sludge, limescale and debris, by pumping water with a powerful flushing machine and chemicals through the heating system. The special chemicals that are added, breakdown the sludge and iron oxide that have built up within your heating system. By Power Flushing your heating system you will restore your system to top condition which in turn will increase the energy efficient heating and life span of your boiler and central heating system.

A Power Flush will help you avoid cold spots on your radiators associated with sludge and debris build up. Power Flush can also reduce the risk of boiler breakdown and improve your home's overall energy efficiency. The Power Flushing process can take between 5 and 8 hours, depending on how many radiators you have.
