Why Has Your Hot Water Stopped?
Usually a failed element, a faulty thermostat or a problem with the circuit feeding the heater. All three are electrical repairs.
On off-peak? Energex switches that supply on a schedule, so cold water can mean it hasn't reheated yet.
We test the parts, replace what's failed, and quote a fixed price first.

A Tingle from a Tap
It can mean a wiring fault in or near your home. Call Energex on 13 19 62, keep clear, and don't touch the switchboard or taps.
Electric Hot Water Needs Checking
The regulator says electric hot water systems need regular inspection and maintenance. Pay extra attention if yours is exposed to the weather.
Plumber or Electrician
Some plumbers hold a restricted electrical licence for hot water work. WorkSafe says a restricted licence doesn't permit electrical installation work.
No Safety Switch on the Power Points
In a home with no safety switch on the general power points, an electrician generally can't do installation work unless the job includes fitting one. Emergency and safety work are among the exceptions.

What Sets the Price of a Hot Water Repair
We test before we price. These are the things that move the number.
- The failed part. An element, thermostat or the circuit itself.
- Access. Tight cupboards or roof spaces take longer.
- Circuit faults. Damaged cable or isolators found in testing get fixed.
- Parts for your model. Some brands need specific elements or thermostats.
- Off-peak supply. If the fault is in the supply, we tell you who to call.
- Weather exposure. Outdoor heaters can have weathered parts to replace.

Hot Water Electrical FAQ
Questions Gold Coast homeowners and landlords ask us about electric hot water.
Why is my electric hot water system not working?
The usual causes are a tripped circuit or safety switch, a failed element, a faulty thermostat, or a problem with the off-peak supply. Check the switchboard first. If the hot water circuit or a safety switch has tripped, you can reset it once. If it trips again, or there's still no hot water, leave the cover on the heater and call a licensed electrician.
Is it the element or the thermostat that's failed?
Both are common, and the symptoms overlap. A failed element often means no heating, or lukewarm water in a heater with two elements, and a leaking element can trip the safety switch. A faulty thermostat can leave water too hot, lukewarm or cold. The only way to know is to test each part with the power isolated. We test, replace what's failed, and run the heater before we leave.
Do I need a plumber or an electrician for my hot water system?
It depends on the fault. Elements, thermostats, wiring, the isolator and the circuit are electrical work. Leaks, valves, the tank and pipework are plumbing. Some plumbers hold a restricted electrical licence for hot water work, but WorkSafe says that licence doesn't permit electrical installation work. We'll tell you plainly if your fault is a plumber's job.
Why does my hot water system keep tripping the safety switch?
Usually current is leaking to earth, often from a failed element or moisture getting into the electrical parts. The safety switch is doing its job. Don't keep resetting it, and don't bypass it. Leave it off and call a licensed electrician. It's often a repairable fault rather than a reason to replace the whole system, and we test to find where the leak is.
Why is my off-peak hot water cold?
Off-peak heaters only get power during set hours. Energex says Super Economy supplies 8 or more hours a day, around 10pm to 7am, and Economy supplies 16 or more hours, usually outside 4pm to 9pm. Times can change with network needs. Cold water can mean the heater hasn't reheated yet, or a fault in the heater or its supply. We test to find which.
How much does a hot water system repair cost?
It depends on the fault, so we don't give a price before we've tested it. The main factors are which part has failed, how easy the heater is to get to, any damage found in the circuit or isolator, and the parts your model needs. We test, then give you one fixed price before work starts. No hourly rate, and you pay on completion by EFTPOS.
Should I repair or replace my hot water system?
If the tank is sound and the fault is electrical, a repair is usually the sensible choice. Elements, thermostats and isolators can all be replaced on their own. If the tank is leaking or rusted through, that's a replacement and a plumber's job, and we'll tell you so. We test the electrical side first and give you an honest view before you spend anything.
What should I do if I get a tingle from a tap or shower?
Stop using it and keep everyone clear. The Electrical Safety Office says to contact your electricity distributor straight away, which is Energex on 13 19 62 on the Gold Coast, available 24/7. Don't turn the power off at the switchboard or touch taps or appliances until it's made safe. If anyone has been shocked, get medical advice, and call 000 if they're hurt.
