WHAT FAILS HERE
Heating faults common in Balham
Working in Balham, we see a clear pattern: the original charm of an unmodernised home often goes hand-in-hand with a heating system that's quietly suffering from decades of internal corrosion.
01
Sludge-related boiler lockouts and cold spots
Older systems that have never been cleaned accumulate magnetite, which can clog the heat exchanger or cause circulation problems. An engineer will check for black, sludge-like water at radiator bleed points and inspect the magnetic filter, if fitted, to assess contamination levels.
02
Noisy pumps and failing radiator valves
System contamination causes abrasive wear on moving parts. The grinding noise from a pump or a radiator valve that won't shut off properly can indicate widespread sludge. Diagnosis involves checking pump bearings and valve internals for black deposit build-up.
