Power Flush
Symptoms which indicate that a central heating system would benefit from a power flush are:
· Radiator water is dirty and discoloured.
· System is slow to warm up.
· Some radiators are partially or completely cold.
· Radiators need frequent bleeding.
· 'Kettling' noises from boiler.
· Repeated pump failures.
· The boiler knocks and bangs, especially at start up.
· The central heating header tank is warm, or even hot.
· Age: Systems over 10 years old will have a build up of corrosion.
Feeling the chill? When you turn your heating on after the summer you may find that it doesn't work as well as you remember it did....Look for the symptoms of sludge and scale: a noisy boiler and cold spots on radiators. The remedy? have your system power flushed!
