Our powerflush service provides a deep clean for your central heating system, clearing any corrosion and sludge that can build up over time. In doing so, a powerflush will increase the heat output from your radiators and improve the overall efficiency of your heating system.

The powerflush process involves attaching a machine to your central heating system at a suitable connection point. Chemicals and water are then circulated around your system at high velocity, in the regular and opposite direction of the water flow. We will isolate individual radiators and circulate the chemicals through each one, making sure each radiator is working efficiently and heating up properly.

If you are having any problems with individual radiators, let us know beforehand and we will focus on that radiator until it is back up to temperature.

An additional advantage of our powerflush service is that we attach a magnetic filter to collect any magnetic particles circulating around the system, removing them completely and preventing them from entering the system again.

A powerflush usually takes around six hours to complete properly. However, this will depend on the condition of your heating system and any problems that you are experiencing.

Typical signs that your system will need a powerflush are:

  • Cold spots on radiators
  • Radiators not heating up
  • Noises coming from central heating system
  • Radiators slow to heat up
  • Dirty water coming from the radiators when bleeding
  • Constant air build up in particular radiators
