WHAT FAILS HERE
Heating faults common in Collier Row
In Collier Row, where home extensions are popular, the heating system is frequently stretched beyond its initial design, making the expansion vessel a common point of failure that requires specific testing.
01
Frequent pressure loss in the boiler
Adding radiators or changing pipework can overload a system's original expansion vessel, causing the pressure relief valve to discharge water. An engineer will test the vessel's pre-charge pressure with a gauge and check for signs of leakage from the relief valve pipe outside.
02
Cycling due to a waterlogged expansion vessel
A failed expansion vessel diaphragm leads to rapid pressure spikes and drops, causing the boiler to cycle on and off. Diagnosis involves observing the pressure gauge during boiler operation and manually checking the vessel's airside with a tyre gauge to confirm it has taken on system water.
