Hard-water suburbs in Joburg are tough on geyser elements — calcium scale accumulates on the heating surface, the element overheats, and eventually it fails. We drain, descale the tank, replace the element with a matched-wattage SABS-approved unit, and recommission. Often combined with a thermostat refresh.
What we do
Drain the tank, remove failed element, descale chamber, fit new element with new gasket, refill and bleed air, test for full heat-up cycle.
Geyser element fault symptoms
What the symptom tells you about the element.
| Symptom | Likely cause | Fix |
|---|---|---|
| No hot water at all | Failed element or thermostat | Test & replace element |
| Hot runs out fast | Failed lower element (twin) | Replace lower element |
| Trips the breaker | Perished element leaking to earth | Replace element |
| Lukewarm only | Element or thermostat fault | Test both |
