Power Flushing, What is it?


Power flushing  is the expression used in the heating trade to denote the process by which the radiators, pipework and sometimes boiler are forcibly cleaned using water at high velocity but at a low pressure, so that no damage to the system occurs.


A machine with a powerful pump is connected to the heating circuit to enable a high flow rate of water into the heating circuit which can effectively purge the system of sludge, scale and other corrosion products.

Once the debris and sludge have been mobilised the power flushing machine pump forcibly expels it from the system using a high velocity of fresh water.


To make the process even more effective chemicals are often added depending on the system type and nature of the problem.

Why do I need a Power Flush?

The problem - black metal oxide sludge (rust) the build up of this sludge in your central heating system over a period of time is inevitable especially if the system water is left untreated of any chemicals such as a inhibitor.

When the sludge in a heating system starts to build up typical problems are:

Radiators cold at the bottom
Radiators cold at the top and need frequent bleeding
No heat distribution to the radiators or very poor
Boiler cutting out
Noise from boiler
Poor or no hot water
High Fuel Bills
Boiler failure

By far the greatest risk to a untreated system is boiler failure - a expensive and disruptive occurrence. A improperly or unprotected system with a build up of sludge may suffer boiler noise (thumping, drumming and knocking) due to excessive lime scale or sludge build up. Eventually the insulating effects of sludge and lime scale will restrict the heat exchanger (the engine of a boiler) to the point where it overheats and fractures.

Sludge will seriously effect the efficiency of a system which will lead to higher fuel bills and premature failure of a boiler and other heating components such as valves and pumps.
