WHAT FAILS HERE
Heating faults common in Southall
In Southall, some long-established homes have heating systems that have been quietly corroding for decades. The issue is often one of internal chemistry, not a sudden component failure.
01
Sludge build-up causing cold radiator patches
Older systems, often with original iron radiators and pipework, are prone to internal corrosion (magnetite). An engineer will check for black, sludge-like water at radiator bleed points and assess if a power flush is needed to remove the contaminant and restore heat output.
02
Noisy boiler and pump due to system contamination
Magnetite sludge can circulate and cause wear in the pump and heat exchanger. The engineer listens for kettling or grinding noises and may inspect the system filter (if fitted) or a radiator tail for black deposits to confirm widespread contamination.
