WHAT FAILS HERE
Heating faults common in Wallington
In Wallington, the reliable family homes of a certain era often have equally long-serving heating systems, where neglect rather than failure is the primary issue we address.
01
Sludge-related boiler lockouts and cold spots
Decades of corrosion in an unflushed system leads to magnetite sludge, which can block heat exchangers and cause overheat faults. An engineer will check for black water at radiator bleed points, inspect the system filter if fitted, and assess the need for a power flush based on the debris found.
02
Noisy pumps and ineffective radiators
System contamination causes abrasion in the pump and restricts flow through radiator valves, resulting in knocking sounds and uneven heating. Diagnosis involves listening to the pump for grinding, checking radiator inlet temperatures for large variances, and testing for magnetic sludge around the pump body.
