When your geyser is powered but you have no hot water (and the breaker hasn't tripped), the thermostat is almost always the cause. We stock thermostats for every major brand and replace in under an hour, retest under pressure and recommission. Saving you an unnecessary geyser replacement.
What we do
Isolate power, drop the front cover, test the thermostat with a multimeter, replace, set to the correct temperature (we recommend 55–60°C for energy efficiency and safety), and re-test.
Our process
- 1Confirm no hot water (not tripped breaker)
- 2Isolate power at the DB
- 3Test thermostat and element
- 4Replace failed part
- 5Reset and recommission
