Power Flushing 
Power flushing is the process by which the central heating system of a house is flushed clean of rust, sludge and any other debris that may have accumulated. 

If you are noticing any of the following symptoms, then you may need your system flushing: 

Boiler switching on and off frequently (aka ‘cycling’) 
Boiler constantly breaking down 
If you have a combination boiler you may notice that the hot water keeps getting hot and then cold. A non-stable temperature may continue to get worse, until you do not get any hot water at all. 
Boiler making banging and/or knocking noise 
Central heating radiators taking a long time to heat up 
Radiators getting cold spots 
Radiators not getting very hot when the pipe work is getting hot 
House always feels cold even when the heating’s on 
Boiler making a kettle noise (resembles a kettle boiling!) 
Discoloured water when you bleed the radiators and in some severe cases when you run the tap

This is a time consuming process and can take up to a full day depending on the type and size of your property. 
 
A powerflush is a deep clean for your central heating system. Using a special machine and cleaning chemicals, we remove sludge, rust, and debris from your pipes, radiators, and boiler. This helps your heating work more efficiently, prevents breakdowns, and keeps your home warm and comfortable. 
 
We usually recommend having a powerflush every 5 to 6 years, or whenever you’re having a new boiler installed. Over time, sludge and debris naturally build up in your heating system, and a powerflush helps keep everything running smoothly and efficiently. 
 
If you notice signs like cold spots on radiators, slow heating, or strange boiler noises in between, it might be worth booking a check sooner. Regular maintenance can save you from bigger issues (and higher repair bills) later on.
