Boiler Losing Pressure in Irene
System pressure falls and the boiler needs repeated topping up. This page covers how we diagnose and repair it on boilers in Irene.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Guest houses, offices and residential estates with mixed gas and heat pump hot water. Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan.

What causes boiler losing pressure?
The usual causes are leak in the system pipework or radiators, failed expansion vessel, passing safety valve, heat exchanger leak. Which one it is can only be confirmed by measurement, not by symptom alone.
How do you diagnose it?
Isolate sections and pressure test; Expansion vessel charge check; Inspect safety valve discharge for flow; Verify gauge against a calibrated instrument. The readings are recorded so the repair decision is based on data.
Can I keep using the system in the meantime?
Usually yes, for a short period, but efficiency and component life are both being lost while the fault persists.
Do you attend this fault in Irene?
Yes. Midrand and Centurion sit between the Johannesburg and Pretoria routes, so attendance windows are usually the shortest of any area. Gas boiler servicing and heat pump maintenance often combined in one visit.
