WHAT FAILS HERE
Heating faults common in Welling
Working in Welling, you learn to anticipate the distinctive signs of an original, sludge-filled system the moment you enter a property of a certain age, often confirmed by the state of the water in the expansion tank.
01
Cold spots at the bottom of radiators and system noise
Decades of corrosion in an unmodernised system leads to magnetite sludge settling in radiators, blocking heat output. An engineer will confirm this by checking for black, magnetic sludge when bleeding a radiator and assessing if a power flush is needed.
02
Inefficient boiler operation and frequent breakdowns
Sludge and contamination circulate, causing damage to the boiler's heat exchanger and components like the pump. Diagnosis involves checking system water quality with a magnet and inspecting the boiler's internal parts for restricting debris.
