Electric Hot Water Repairs & Installation
When your hot water stops working, it's usually an electrical issue — a failed element, a tripped thermostat, a faulty tempering valve, or a problem with the dedicated circuit at the switchboard. Randwick Electrical diagnoses and repairs electric hot water system faults across Sydney's Eastern Suburbs, and we install new systems when replacement is the smarter option.
Common Hot Water Electrical Faults
- No hot water at all — often a failed heating element or tripped thermostat. We test both and replace as needed. Could also be a tripped circuit breaker at the switchboard
- Water not hot enough — thermostat calibration issue, failing element (partial heating), or a faulty tempering valve that's mixing too much cold water
- Tripping safety switch — a leaking element can cause earth leakage that trips the RCD. This is the most common hot water-related electrical fault
- Off-peak tariff issues — if your system runs on a controlled load (off-peak) circuit and isn't heating, there may be a meter or relay issue. We coordinate with your energy provider when needed
- Tank leaking — if the tank itself is leaking (not a valve), the unit typically needs replacement. We handle the electrical disconnection, new unit connection, and circuit upgrades
Hot Water System Installation
When it's time for a new system, we handle all electrical aspects of the installation:
- Disconnection and removal of the old system's electrical supply
- Dedicated circuit installation or upgrade for the new unit
- Connection to controlled load (off-peak) metering if applicable
- Heat pump hot water system wiring — increasingly popular as an energy-efficient alternative
- Solar hot water booster element connections
- All testing and certification
