Electric Hot Water Systems

An electric hot water system is a water heating solution that uses an electric heating element submerged in an insulated storage tank to heat and store hot water for household or commercial use. Available in various tank sizes from 25L to 400L, electric systems are the most widely installed type of hot water system in Australia due to their simple installation, low upfront cost, and compatibility with all homes regardless of gas availability.

An electric hot water system heats water using one or two electric heating elements submerged inside an insulated storage tank. When the water temperature drops below the thermostat's set point, the element switches on and heats the water to the set temperature, typically 60 degrees Celsius. Hot water is stored at the top of the tank and drawn off when a tap is opened, with cold water entering at the bottom to be heated. A pressure relief valve prevents dangerous pressure buildup inside the tank.

A quality electric hot water system typically lasts 10 to 15 years with regular servicing. The heating element and thermostat can often be replaced without replacing the whole unit. A sacrificial anode rod inside the tank slows corrosion and should be checked every 5 years. SunCity Hot Water provides servicing and repairs across the Sunshine Coast, Brisbane and Gympie.

To turn off an electric hot water system, locate the dedicated circuit breaker in your switchboard, usually labelled HWS or HOT WATER, and switch it off. To fully isolate the system, also turn off the cold water supply valve at the base of the unit. If your system is leaking or the pressure relief valve is releasing hot water, turn off both power and water immediately and call SunCity Hot Water on 1300 728 122 for urgent repairs across the Sunshine Coast, Brisbane and Gympie.
