WHAT FAILS HERE
Heating faults common in Earlsfield
In Earlsfield, a history of home improvements is common, and we frequently trace pressure problems back to an expansion vessel that hasn't been upgraded to match the now-larger heating system.
01
Frequent pressure loss in extended systems
Adding radiators or underfloor heating to an existing sealed system increases its water volume, which can overwhelm the original expansion vessel. An engineer will test the vessel's pre-charge pressure and check for signs of water discharging from the pressure relief valve.
02
Boiler cycling due to expansion issues
If the expansion vessel is waterlogged or too small, pressure spikes can cause the boiler to shut down on safety. Diagnosis involves monitoring the pressure gauge during a heating cycle and manually checking the vessel's airside pressure with the system drained.
