WHAT FAILS HERE
Heating faults common in Charlton
Charlton has a stock of homes with original heating installations, where decades of corrosion without inhibitor have turned the system water into a problematic slurry.
01
Sludge build-up causing cold spots on radiators
Older steel or iron systems that have never been cleaned accumulate magnetite sludge, which settles in radiator bottoms and small-bore pipes. An engineer will check for cold patches at the base of radiators, inspect the water in the feed tank, and may use a magnetic filter probe to confirm contamination before recommending a power flush.
02
Noisy boiler and pump due to system contamination
Circulating black, magnetic sludge acts as an abrasive and can cause kettling noises in the heat exchanger and wear in the pump. Diagnosis involves listening for gurgling or grinding sounds, checking the pump for seized bearings, and examining any in-line filters for a rapid buildup of black residue.
