WHAT FAILS HERE
Heating faults common in Moorgate
Around Moorgate, the age of the infrastructure means we frequently encounter systems that have never been thoroughly cleaned, leading to predictable but stubborn circulation faults.
01
Sludge and magnetite build-up in old pipework
Unmodernised systems in these buildings often have decades of corrosion circulating, which settles as black sludge. An engineer will check radiator water colour, feel for cold spots at the bottom of rads, and use a magnetic filter to inspect for ferrous debris.
02
Recurring boiler lockouts due to poor water quality
Contaminated water can cause blockages in critical components like the heat exchanger or pump. Diagnosis involves checking system pressure, inspecting the magnetic filter if fitted, and often recommending a power flush to restore clean circulation.
