5 000 Litre Geyser Not Heating in Pretoria North
A large storage geyser is not reaching temperature or recovers far too slowly. This page covers how we diagnose and repair it on hot water systems in Pretoria North.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Older residential stock plus light industry, with many element geysers still in service. Gauteng municipal water is moderately hard, so scale on elements and heat exchangers is the single most common cause of falling performance.

Current draw per element circuit; Contactor and timer function test; Probe calibration against a reference; Coil delta-T measurement. 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.
