- Are your radiators slow to warm up, do they have cold spots?
- Do they require frequent bleeding/venting?
- Pinhole leaks on radiators?
- Does your boiler make strange/unpleasant noises?
- Does your boiler overheat/lockout?
- Does your system suffer from frequent pump/motorised valve failures?
- Is there a long recovery time after drawing hot water?
- Do you have sticking thermostatic radiator valves?
Any of these symptoms could indicate that your heating has circulation problems and you probably would benefit from a powerflush. A powerflush can restore your system by removing magnetite sludge and corrosion debris. After flushing, your heating system is left with clean water that has been treated with a corrosion inhibitor, this will prevent future sludge related problems
Fitting a new boiler to an existing heating system?
The high efficiency and compactness of modern boilers, developed to minimise running costs and pollution, makes them more susceptible to problems caused by debris in the system water (click on the video below). Manufacturers insist that heating systems must be thoroughly flushed before installing a new boiler. Boiler manufacturers will not cover faulty components due to poor water quality. A powerflush is far more effective then traditional flushing methods, and ensures that the boiler installation complies with ‘best practice standards'.
