Power Flushing

Power FlushingPower flushing is sometimes referred to as Jet Flushing or Hard Flushing. The aim of power flushing is to restore your central heating systems to optimum operation. Power flushing removes sludge and corrosion deposits that might be causing your boiler to make noise or prevent water circulating correctly.


New Boiler and Power Flushing

If you are having a new boiler fitted, it is advisable to have your central heating system flushed to remove corrosion deposits and sludge. These are usually found in systems even if no symptoms have shown. These deposits can be mobilised when alterations are made to the system and find their way into the new boiler heat exchanger, causing noisy operation, reduced efficiency and, in extreme circumstances, failure of the boiler.

Once the flushing process is complete, the system will contain fresh, clean water. Your central heating system is reverted to normal operation in minutes.


Power Flushing and Metal Particles

Over time, your central heating system can gradually build up deposits of metallic particles that could potentially damage your central heating boiler. The images below show a central heating system recently power flushed by us.

Once these particles have been removed from your central heating system, it may be worth considering installing a central heating filter, which can prevent future circulation of metallic particles..
