WHAT FAILS HERE
Heating faults common in Wealdstone
The older heating systems in Wealdstone properties are often reliable workhorses, but years without a flush can lead to significant efficiency losses from internal sludge.
01
Cold spots at the bottom of radiators
This is a classic sign of sludge build-up, where magnetite from internal corrosion settles and blocks heat transfer. An engineer will check by feeling the radiator's temperature distribution and may drain a small amount of water to look for black, gritty deposits.
02
Boiler overheating or noisy pump operation
Sludge circulating through the system can cause blockages in the heat exchanger or pump, leading to restricted flow and overheating. The diagnostic involves checking the pump for resistance, listening for bearing noise, and examining the system water for contamination, which often indicates a power flush is needed.
