Power Flushing FAQs.

Prices can vary due to how many radiators are installed on your central heating system, the design and layout of your central heating system and type of boiler. On average you are looking at anywhere between £400 - £800.

Yes. Power flushing is a good idea as it can help the lifespan of your central heating system, improve the efficiency and reduce bills with warmer radiators with the boiler working to its full potential after sludge has been removed from the system.

You should power flush your central heating system before replacing radiators because if there is sludge and magnetite in the pipework and boiler, this would also get into the new radiators. The sludge should be flushed out first.

A power flush done correctly from a reputable company will remove almost all sludge in your central heating system, helping to increase the lifespan of your boiler, radiators and central heating system.

A power flush can take anything from 4 hours to 8 hours to complete, depending on the size of the central heating system and how badly sludged the boiler and radiators are. This will have the biggest factor how long the flush will take.

Power flushing cannot damage a boiler. What a power flush does is move water at a high rate under controlled conditions with chemicals through your boiler, pipework and radiators using a high-tech full spec pump.

A build up of limescale and debris in the heat exchanger is generally the most common issue for this. Power flushing can help prevent this.
