WHAT FAILS HERE
Heating faults common in Angel
Around Angel, the very period features that attract buyers are often paired with heating systems that have been quietly corroding for decades, needing a thorough clean-out.
01
Sludge-related boiler kettling and noise
Long-serving systems in unmodernised properties often have significant magnetite build-up from internal corrosion, which insulates heat exchangers and causes localised boiling. An engineer will check for black, sludgey water at a radiator bleed point and may use a magnetic filter inspection to confirm contamination.
02
Cold spots at the bottom of radiators
This is a classic sign of sludge settlement blocking the bottom channel of the radiator, common in systems that have never been power-flushed. The diagnostic process involves feeling the radiator's temperature distribution and assessing the need for a system cleanse based on water samples.
