WHAT FAILS HERE
Heating faults common in Morden
Working on the original heating systems in Morden's interwar homes often involves planning for a power flush to clear out years of accumulated sludge and corrosion products.
01
System sludge causing cold spots and boiler lock-outs
Decades-old systems in unmodified properties often suffer from magnetite sludge build-up, which blocks heat exchangers and small-bore pipes. An engineer will inspect the water in the system for discolouration, check for cold spots at the bottom of radiators, and may use a magnetic filter to assess contamination levels.
02
Corrosion and blockages in old iron pipework
The original iron pipework common in these properties is prone to internal rusting, which flakes off and circulates. This can lead to repeated pump failures and noisy operation. A common diagnostic step is to check the pump itself for seized bearings caused by debris and to assess the system's water quality.
