power flush machinePower flushing a central heating system

Sometimes, there will a a blockage in your central heating pipes that just can't be moved. In extreme cases this can mean cutting out the pipework and replacing it which can become costly and time-consuming. Power flushing is a powerful preventative measure that should be carried out on your central system regularly to stop blockages before they develop and to prolong the life of your system.

What is power flushing?

Power flushing removes sludge and limescale build-up from your central heating pipework by forcing water through the pipes at high speed in conjuntion with special cleaning chemicals that can only be used in conjunction with the power flushing process. It is essentially a high velocity cleaning of your central heating system. The chemicals used will not cause any damage to your system as we thoroughly rinse the system through after the power flush to remove all traces.


Check out this video from Worcester Bosch and see how power flushing can help keep your central heating system in good condition.
