5 000 Litre Geyser Not Heating in Craighall Park
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 Craighall Park.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Craighall Park sits within the Rosebank belt, with larger stands, long hot water runs and frequent pool heating. Static pressure and dead-leg length are checked as part of any hot water complaint here. Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan.

FAQs
Frequently asked questions
What causes 5 000 litre geyser not heating?
The usual causes are part of the element bank failed, contactor or timer keeping elements off-line, load shedding control limiting heating windows, thermostat or probe misreading. Which one it is can only be confirmed by measurement, not by symptom alone.
How do you diagnose it?
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.
Do you attend this fault in Craighall Park?
Yes. Technicians work out of the central Johannesburg base, which keeps travel time short for northern-suburb call-outs. Craighall Park visits carry heat pump and geyser spares together, since both are commonly installed on the same property.
