Powerflushing 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.
A high flow/low pressure pumping unit is attached to the heating system circulation pump and a series of strong cleansing chemicals are flushed through the entire system
Unfortunately powerflushing is quite an expensive process and you should only have one if you really need it. So how do you know when your heating system needs to be flushed?
The signs to look for
There are a few common signs that indicate powerflushing is needed and these include:
- Cold spots on the radiators or radiators that don’t heat up at all
- Discoloured water when you bleed the radiators or in severe cases when you run the tap
- Excessive noise from the boiler unit or the circulation pump
- Poor or non-existent hot water even when the system has been running for a while
These problems on their own may be able to be rectified without powerflushing, however, if you notice more than one sign then it is probably worth considering a powerflush.
