WHAT FAILS HERE
Heating faults common in Streatham
Streatham has many well-loved family homes where the heating system has been maintained but never fully renewed, so discovering a sludge-filled system is a typical finding.
01
Sludge-related boiler lockouts and cold spots
Older systems that haven't been cleaned can accumulate magnetite, which circulates and eventually blocks heat exchangers or small-bore pipes. An engineer will look for black, gritty water when bleeding a radiator and may use a magnetic filter inspection to confirm significant contamination.
02
Noisy operation from pump and pipework
Build-up of corrosion debris can cause kettling sounds in the boiler and gurgling in the pipes, as water flow is impeded. The diagnostic process involves checking the system water with a cleanliness indicator and listening for pump cavitation, which strongly points towards the need for a power flush.
