WHAT FAILS HERE
Heating faults common in Cheam
Around Cheam, we often find that the charm of period homes comes with the complexity of later modifications, where heating systems have been stretched to their limits.
01
Cold upper-floor radiators after loft conversion
Adding a loft conversion often extends the heating circuit without properly rebalancing the system, leaving the new or existing upper-floor radiators starved of flow. An engineer will check for airlocks in the new pipe runs, verify the pump's capacity, and test the system balance to ensure hot water reaches the highest points.
02
Gurgling noises from extended pipework
Extensions can create high points in pipework where air naturally collects, leading to persistent airlocks. The diagnosis involves tracing the new circuit layout, checking for incorrect pipe fall, and systematically bleeding at the highest possible point, which is often not at a standard radiator valve.
