Power flushing is a great way to ‘rescue’ your heating system, and if you’re looking for professional power flushing services, MPN Plumbing & Heating Services Ltd has the solution. Central heating systems become less efficient over time, due in part to a build up of iron oxide (more commonly referred to as black sludge).


Why have your system power flushed:


  • Cures flow and circulation problems

  • Restores system efficiency

  • Restores heat output to radiators

  • Cleans the whole system, including under floor pipework

  • Reduces pump failure problems

  • Removes aggressive water and treatment prevents further corrosion

  • Cures or prevents boiler noise

  • Power flushing and descaling in one visit

  • Minimizes boiler warranty problems



Power flushing is a highly effective cleansing operation, which works by pumping water at a much higher velocity than usual through the heating system, to loosen and mobilizing harmful corrosion deposits, and to suspend them in the rapidly moving water. The process is made more effective by specialist cleansing chemicals, an instantaneous flow reversal device, which creates turbulence in the radiators to optimize ‘pick up’ of the debris, and a magnetic filter to clean the system water during the power flush.

Once loosened, the unwanted debris is purged from the system with clean water. At the end of the flushing process, the system contains fresh clean water, and reinstatement of the system to normal operation takes only a few minutes.

During the process, radiators are individually flushed, without removing or disconnecting them from the system, by directing the full output of the power-flushing pump through each radiator separately.


Power flushing is carried out with minimal disturbance and disruption to the normal operation of the system, often without disconnecting the boiler of radiators.
