WHAT FAILS HERE
Heating faults common in Coulsdon
Coulsdon's housing stock includes several estates with shared heating infrastructure, where a fault in one home requires an understanding of the wider system's layout and balancing.
01
No heating or hot water in one flat only
In buildings with a communal boiler or branched heating circuits, an individual flat's problem is often isolated to its own branch. An engineer will first locate and check the status of the flat's specific isolation valve or zone valve, ensuring it is open and receiving power, before tracing the pipework for a localised blockage or airlock.
02
Inconsistent heat between neighbouring apartments
Poor balancing of the shared system can lead to some flats being too hot while others are cold. Troubleshooting involves checking the adjustment of the lockshield valves on each radiator within the affected flat and may require assessing the balance across the building's main distribution pipes to ensure even flow.
