The Electric Hot Water Jobs We Do
Electric storage tanks in the laundry, a cupboard or outside, fixed or replaced at a price agreed first.
No Hot Water Or Only Warm
The tank is on but the water runs cold or lukewarm. On an electric system that usually points to the heating element or the thermostat, and we tell you if it is worth repairing.
Leaking Tanks And Relief Valves
A relief valve that keeps running can often be replaced on its own. Water coming from the body of the tank means the inner tank has rusted through and the tank needs replacing.
Low Hot Water Pressure
Strong cold water but a weak trickle of hot usually traces back to a valve on the water line into the tank, which we find and fix.
Compact Tanks In Laundries
Small and mid-size electric tanks tucked into laundry corners and cupboards, fixed where they sit or replaced with a new tank that fits the space.
How Bad Is Your Electric Hot Water Problem?
Three electric hot water problems we see often, and what to do about each.
Tank Leaking Now
Switch the hot water off at the switchboard first, then turn off the cold water valve on the pipe into the tank so it stops refilling, and call. Keep clear if water has reached the power point or wiring.
Cold Or Only Lukewarm
Check the hot water circuit breaker at the switchboard. If it trips again when you switch it back on, leave it off and book us in, as that often means the element has failed.
Relief Valve Dripping
A small drip from the relief valve drain while the tank heats is normal. A steady flow that does not stop is not, so book it in before it wastes more hot water.
How We Fix Electric Hot Water Systems

Electric Hot Water Systems FAQs
Answer:
It depends on the tank size, whether it is a like-for-like swap, how easy the spot is to reach, and which valves need replacing. You get one fixed price for the tank installed before any work starts, and nothing is charged until you say yes. Current Sydney market ranges for electric, gas, continuous flow and heat pump systems are in our hot water system prices guide.
Answer:
No. The water connections are licensed plumbing work, and the power connection has to be done by someone licensed for electrical work. Most manufacturers also need a licensed install for the warranty to apply.
Answer:
The most common causes are a tripped hot water circuit at the switchboard, a failed heating element or a faulty thermostat. If the circuit trips again when you switch it back on, leave it off and call us.
Answer:
A tank heating from cold can take several hours, depending on its size. On an off-peak tariff the power to the tank is only on for set hours, mostly overnight, so a tank emptied in the evening may not be hot again until the morning.
Answer:
It depends on how many people live in the house, how they use hot water, and whether the tank runs on off-peak power, which needs a bigger tank because it only heats for set hours. We size it on site rather than guessing from a chart.
Answer:
A small drip from the relief valve drain while the tank heats is normal. A constant flow usually means the relief valve needs replacing, and water from the body or base of the tank means the inner tank has rusted through and needs replacing.
Answer:
Scalding water at the bathroom taps usually means a faulty tempering valve, which mixes cold water into the hot on its way to the bathroom. Get it fixed quickly, especially with young children or older people in the house.
Answer:
It depends on whether gas is connected, where the unit can go and how much hot water the household uses. An electric tank can go almost anywhere, including indoors, while gas needs a gas supply and either a flue or an outdoor spot. We price both so you can compare.
