What is Power Flushing?

Power flushing is a surefire method of increasing the performance and efficiency of your central heating system. Some of the symptoms of poor water circulation around the central heating system are:

  • Cold spots in radiators from the top down.
  • A noisy boiler, as it tries tp move sludge and scale.
  • Failing components like the main heating pump.
  • Motorised valves clogged up with sludge deposits.
  • Leaks on radiators and pipework.

A rapid power flush by our technician can revitalise poorly performing radiators and make your whole heating system operate like new.

Power Flush

How does Power Flushing work?

Our power flushing machine is first connected into the central heating system. This can be either across the pump couplings inside the boiler, or to either side of one of the radiators.

The powerful flow of water, combined with a flow reversing device, will dislodge and move deposits and corrosion which resist normal central heating system cleaning methods.

Once the sludge deposits have been loosened and mobilised, fresh clean water is forced through the heating system, pushing the contaminated water out directly into the nearest drain.

Will this treat my whole house?

During the flushing process, radiators are cleaned individually. This is performed without removing or disconnecting them from the heating system, by directing the water flow of the pump through each radiator separately.

Chemicals can be added to the flushing process depending upon the severity of the problem.

How can I prevent my system clogging up in future?

Upon completion of the flushing process, the system contains just fresh clean water, so a corrosion inhibitor will be added to the system to help prevent further problems in the future.

Power flushing of the central heating system will not remedy design or mechanical faults. However these can be addressed whilst the technician is on site to prevent the problem occurring again.

What about magnetic filters?

After power flushing, a cleaning filter can be installed to remove magnetic and non-magnetic deposits. Modern efficient central heating systems are most economical when operating at peak performance. The natural process of black iron oxide build-up soon impairs performance and eventually clogs the boiler and radiators.

Most systems suffer from black iron oxide contamination at some point. This creates thick sludge deposits from the large and sub-micron oxide particles leeching into the system water during use.

Installing a Magnetic type filter to a new or existing central heating system is simple. It comes with purpose designed valves, which allow 360º rotation. Some filters require isolating and removal of the magnetic core, others require just a simple flush through for a few seconds. This can be carried out by the customer or by the engineer at the annual boiler service.
