Power Flushing

As soon as a heating system is completed and filled with water, deterioration of the system begins. The combination of water, air, a mixture of metals, and even installation debris and contaminants, can result in internal corrosion, sludge formation in low flow areas, and scaling of boilers and heat exchangers.

What happens during a power flush?

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 mobilise 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 optimise ‘pick up’ of the debris, and a magnetic filter to clean the system water during the power flush.

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

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 is treated with corrosion inhibitor.

Why do I need my heating system power flushed?

There are many benefits to a power flush such as:

  • Cures flow and circulation problems
  • Restores system efficiency
  • Cleans the whole system, including underfloor pipework
  • Cures or prevents boiler noise

A power flush could be the answer if you are experiencing the following issues:

  • Is the system slow to warm up?
  • Are some radiators completely cold or partially cold?
  • Do radiators need frequent bleeding?
  • Is the radiator water dirty or discolour?
  • Do you have radiators with pin hole perforations and leakage?
  • Are there ‘kettling’ noises from the boiler?
  • Do you have repeated pump failures?
