5 000 Litre Geyser Not Heating in Crowthorne
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 Crowthorne.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Crowthorne is a high-value residential pocket of Midrand, typically with multiple geysers or a heat pump on buffer storage, and in many cases pool or underfloor heating on the same plantroom. Gauteng municipal water is moderately hard, so scale on elements and heat exchangers is the single most common cause of falling performance.

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 Crowthorne?
Yes. Midrand and Centurion sit between the Johannesburg and Pretoria routes, so attendance windows are usually the shortest of any area. Crowthorne falls inside our core northern-suburb route, so response is normally same-day for loss-of-hot-water call-outs.
