- Removes sludge & scale from central heating systems
- Stops boiler noise
- Complete system clean
Central heating systems can gradually build up a combination of scale, sludge and corrosion by products within the boiler, pipework and radiators. This manifests itself as cold spots on radiators, failure to pump to the furthest radiators, and noise in the boiler.
Central heating systems also need to be flushed prior to filling with preservative in order to remove flux and other deposits before commissioning for the first time (BS7593:1992).
It can often be time consuming or impractical to remove radiators for cleaning out severe blockages. Even when they are removed, the only flushing capability usually available is with cold water from a hose at mains pressures and flows. This will not loosen or remove sludge which has bonded to the inside of radiators or the remainder of the heating system.
- Is the central heating slow to warm up?
- Are some radiators completely or partially cold?
- Do radiators need frequent bleeding?
- Is radiator water dirty and discoloured?
- Do your radiators have pin hole perforations?
- Do your radiators leak?
- Do you think you have blocked radiators?
- Are there ‘kettling’ noises from the boiler?
- Do you have repeated pump failures?
