Calorifier Not Heating in Parkmore Ext
The calorifier receives steam or hot water but the stored water stays cold. This page covers how we diagnose and repair it on hot water systems in Parkmore Ext.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Parkmore Ext is an extension of Sandton with a mix of original and renovated housing, so geyser positions, pressure control and pipework standards vary stand to stand. Gauteng municipal water is moderately hard, so scale on elements and heat exchangers is the single most common cause of falling performance.

Valve stroke and actuator test; Trap condition test; Coil hydraulic pressure test; Strainer inspection and temperature survey. 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.
