WHAT FAILS HERE
Heating faults common in Whetstone
In Whetstone, where homes have often been adapted over time, a history of repeated pressure top-ups is a reliable clue that the expansion vessel needs attention following system alterations.
01
Frequent pressure loss in extended systems
Adding radiators to an existing sealed system increases its volume, which can overwhelm a small or failed expansion vessel. An engineer will test the vessel's pre-charge with a tyre gauge, check for drips from the pressure relief valve, and look for signs of micro-leaks in new pipework.
02
Boiler cycling due to expansion vessel faults
A waterlogged expansion vessel causes rapid pressure spikes, triggering the boiler to cycle on high limit. Diagnosis involves monitoring the pressure gauge during heating cycles, listening for the relief valve discharging, and draining the system to check the vessel's airside charge.
