Power Flush In Kent


A power flush is a straight forward cleaning of the internal heating system pipe process which aims to remove deposits of sludge, rust and any other debris from your central heating system. These contaminants, if left, can seriously affect the efficiency the boiler and the heating system and in some situations a power flush is the only option available.


Tell Tell Sign you might need a power flush

There are a number of signs to look for before deciding to go ahead with a power flush. Cold areas on radiators, banging noises from the boiler or the heating system pump, dirty water when you bleed the radiators and the slow warming of the heating system. You might also notice the tap water getting misty, especially if there is a build-up of lime scale in the system.

It is also recommended that the power flush process is carried out if you intend to carry out a new boiler installation in Kent. This is due to the fact that any contaminants already present in the heating system can quickly damage the internal pipe work of the new boiler.




The overall aim of a power flush is to restore the full circulation of water around the central heating system, however, it can also eliminate noise from the boiler and the pump as well. This means that the system needs to be fully flushed in order to get the best results.

A heating engineer will connect a powerful high flow/low pressure pumping unit to the central heating system – either to the circulation pump in regular boiler systems or the pump head in combination boilers – and with the help of high strength cleansing chemicals will flush out anything in the system.

The chemicals used during a power flush include a sludge crust breaker and remover to help get rid of rust and sludge, a de-scaler to break down lime scale and a corrosion inhibitor to stop further rusting from occurring. The crust breaker and remover are acid-based so that they help to combat any rust present and any other deposits, such as sand particles, that might have settled in the radiators, pipe work and boiler. At the end of the process there is no acid left in the central heating system’s water.
