WHAT FAILS HERE
Heating faults common in Catford
In Catford, the tell-tale sign of a recent conversion is often a warm downstairs but a stubbornly cold new bedroom radiator, a common call-out that points straight to an air or circulation issue in the extended circuit.
01
Cold radiators after loft conversion
Adding a loft conversion often extends the pipework beyond the original system's design, making the highest points prone to airlocks. An engineer will check the pump's speed and bleed the radiator in the new room first, then trace the pipe run for any high spots that need automatic air vents.
02
Gurgling pump and poor circulation
Extended pipe runs in converted spaces can create loops where air gets trapped, causing the pump to cavitate and struggle. The diagnostic focus is on checking the feed and expansion tank level (if present) and ensuring the system's automatic bypass valve is correctly set to maintain a minimum flow rate.
