A ‘powerflush’ is the method used to unblock wet central heating systems which over time can become hampered by sludge, rust and debris.
As the name suggests, a powerflush, consists of a surge of water and strong cleaning chemicals being pumped through your central heating system to wash away any build-ups.
This is a great way to ensure your heating system is working at its best, but being as powerflushes are quite expensive (they can cost on average between £350 to £1,200), they should only be carried out when necessary.
There are a few common signs to look out for to indicate when powerflushing is needed:
- Radiators which fail to heat up or have cold spots.
- Excessive noise from the circulation pump or boiler.
- Dirty water when you ‘bleed’ the radiators or when you run the tap.
- Poor heat emissions from your wet central heating system for prolonged periods.
The problems above may be rectified without the need for a powerflush if they occur separately, however, if more than one issue arises then a powerflush should be considered.
The key purpose of a powerflush is to ensure your home is heated efficiently. Pipes with poor circulation and build-up in radiators will require your boiler to work harder to produce heat, which could result in higher energy bills.
