Most central heating systems will have some degree of corrosion which may or may not be causing a problem. This is a build up from different metals mixing within your heating system and breaking down over time due to electrolytic corrosion. If caught early this can be remedied fairly easily with a chemical flush and a magnetic filter, however when the build up increases it can cause problems such as:

  • Cold spots at the bottom of radiators

  • Noisy or 'knocking' boiler

  • Your radiators need bleeding very often and the water is discoloured

  • Your boiler has been on a while and the radiators are only warm

  • The radiators are cold but the pipes are hot


Depending on the size and system type you have installed, a Powerflush can take anywhere between 4 hours and 3 days, so we need to check exactly what problems you are experiencing and what appliances you have installed before giving a quote. Contact us for more information
