WHAT FAILS HERE
Heating faults common in New Malden
Heating systems in New Malden's well-preserved older homes are often the originals, and a lack of inhibitor changes over the years makes sludge-related breakdowns a very common fault we are called to investigate.
01
Sludge build-up causing cold radiator patches
Original iron radiators and steel pipework in long-standing systems corrode over decades, producing magnetite sludge. An engineer will look for cold spots at the bottom of radiators, check for black water when bleeding, and may recommend a power flush to restore flow.
02
Noisy boiler and pump from system contamination
Circulating magnetite acts as an abrasive and can cause kettling noises in the heat exchanger and whining from the pump bearings. The diagnosis involves checking the pump for seized impellers and inspecting the system water for clarity and magnetic particle content.
