Why your electric hot water system has stopped heating, and the fix
Most electric hot water systems work the same way: a power supply, a thermostat and one or two elements inside a storage tank. Pick the symptom that matches yours to see what we check and what happens next.
Look at the circuit breaker for the hot water in your meter box. If it has tripped, switch it back on once and wait for the water to heat.
If it trips again or nothing happens, we test the power supply, the thermostat and the elements in turn, because a failed element is the most common cause.
Most of those parts are on our vans, so a no hot water call is often fixed on the same visit.
Do not open the cover on the tank yourself. The wiring behind it carries mains power.
Lukewarm water usually means one of two elements has failed, or the thermostat is not switching the heat on at the right point.
We test both elements and the thermostat, replace what has failed and set the temperature so it is safe at the taps while the tank stays hot enough to keep bacteria out.
If the tank is simply too small for the household, we say so and show you what size would fit.
Many Sydney homes run an electric tank on an off-peak tariff, which heats the water at set hours. If the water is cold in the morning, the timer or the controller may be at fault.
We check that the tank is on the right circuit and that the heating hours match your tariff, then look at whether the tank is losing heat through ageing insulation or a leaking valve.
If bills are climbing, we can also talk through moving to a heat pump as an option, with no pressure to do it.
A tank that leaks from its body, or one that needs repeated repairs, has reached the end of its life. A new storage tank is the simplest like for like swap.
A heat pump is the other choice. It uses far less electricity for the same hot water but needs space outside and a higher upfront cost, so we work through whether it suits your home.
We install the unit, connect the water and power, remove the old tank and test the temperature before we leave.
If you want gas instead, see our gas hot water page.

What an electric hot water system repair or installation costs in Sydney
Replacing an element and installing a new tank are two very different jobs, and the price follows the work. You get a fixed figure before we begin.
Which part has failed
Elements, thermostats and valves are smaller jobs than a whole tank. A tank that has rusted through cannot be repaired.
The size of the tank
A bigger household needs a bigger tank, and larger tanks cost more to buy and take more care to move.
Where the tank is
A tank by the side of the house is a quick swap. One in a roof space or a tight cupboard takes more time and handling.
Power and tariff work
A tank on an off-peak circuit may need the wiring checked or changed. That part of the work is done by a licensed electrician when it is needed.
Heat pump or storage
A heat pump costs more to buy than a storage tank and uses less power to run. We set both next to each other so you can compare.

Why is my electric hot water system not heating?
Common causes include a tripped circuit breaker, a blown fuse, thermostat issues, or a faulty heating element, which may require professional assessment.
Can I repair my electric hot water system myself?
Basic troubleshooting such as checking the power supply or resetting the system is possible, but internal repairs should always be done by a licensed plumber or electrician for safety reasons.
What size electric hot water system do I need?
The appropriate size depends on the number of people in the household and typical hot water usage - consulting with an expert ensures the system meets daily needs efficiently.
How much does electric hot water repair cost in Sydney?
It depends on which part has failed and how easy it is to reach. An element or thermostat is a smaller job than a new tank. We give you a fixed price after we have tested the system, there is no call out fee, and nothing starts until you agree.
Why does my electric hot water keep tripping the circuit breaker?
A breaker that trips repeatedly is usually protecting you from a failed element, a damaged thermostat or water reaching a live part. Do not keep resetting it. Leave it off and call us so a licensed plumber can find the fault safely.
How long does an electric hot water system last?
Many electric storage tanks last around ten years, sometimes longer with a working anode and good water. A tank leaking from its body is finished. Elements and thermostats can be replaced, so an older tank in good condition is often worth repairing.
Is a heat pump worth upgrading to from an electric tank?
It uses much less electricity for the same hot water, so it can lower running costs. It costs more to buy and needs space outside for the unit. Whether it pays back depends on your usage, so we look at the household before suggesting it.
What does off-peak electric hot water mean?
Off-peak means the tank heats at set hours, often overnight, when the power tariff is lower. The tank has to hold enough hot water for the day. If the water runs out early, the tank may be too small or the timer may need checking.
Which parts of Sydney do you service for electric hot water?
All of it: the Sutherland Shire, Inner West, Eastern Suburbs, North Shore, Northern Beaches, the Hills District, Canterbury-Bankstown, Western and South West Sydney and the City. Our vans are fully stocked with common electric hot water parts.
Can I replace an electric hot water element myself?
No. The element sits in a tank that carries mains power and hot water, and in NSW, work on the water connections needs a licensed plumber. A wrong fit can cause burns, leaks or electric shock. Call us and we will do it safely.
Do you service electric hot water systems before they fail?
Yes. Servicing checks the relief valve, the anode, the thermostat, the elements and the pipe connections, and it can add years to a tank. It is also a good moment to ask whether the unit still suits your household. A complimentary safety inspection comes with it.
