WHAT FAILS HERE
Heating faults common in West Drayton
In West Drayton, the prevalence of home improvements and extensions means we frequently trace pressure issues back to alterations where the heating system's expansion capacity wasn't reassessed to suit the new, larger volume of water.
01
Boiler losing pressure repeatedly, requiring frequent top-ups
Properties that have been extended often have undetected minor leaks in new pipe runs or suffer from a failing expansion vessel. An engineer will test the vessel's pre-charge pressure with the system drained and check for pressure drop over time with the boiler cold to isolate a leak from a vessel fault.
02
Pressure relief valve discharging water outside
A vessel that has lost its air charge or is waterlogged cannot absorb the expansion of heated water, causing system pressure to spike and lift the safety valve. Diagnosis involves checking if the vessel's diaphragm is intact and if the filling loop has been left slightly open, introducing excess pressure.
