07/10/2025 A reliable hot water system keeps things comfortable, but if your energy bills are creeping up, it's time to look at what's driving the costs. For homeowners in Canberra, being mindful of how your system works and how it's maintained can make a big difference. Whether you're using an electric or hot water system in Canberra, a few small changes can deliver long-term savings.

Choose the Right System for Your Home

Older systems can be energy-hungry, especially if they're working harder than needed. If your household has changed, maybe fewer people at home now, your current system might be oversized. On the other hand, if you're running out of hot water too soon, you could be overusing an undersized unit, which also drives up running costs.

Upgrading to a more efficient option like a gas hot water system in Canberra can help reduce costs over time. Gas units tend to heat water faster and operate more efficiently, especially in colder climates. If you're replacing an old system, it's a good time to assess your actual usage needs before selecting a new one.


Check Temperatures and Settings

Many systems are set to higher temperatures than necessary. Lowering the thermostat to around 50-55°C for stored water (and 60°C at the tank to prevent bacterial growth) can help you save on energy without affecting comfort. Always check with your technician before making adjustments, especially if you have a storage system, as safety standards apply.


Fix Leaks and InsulateThat slow drip from your tap might seem harmless, but even a minor leak can waste thousands of litres of hot water annually—translating directly into higher bills. Fix leaking taps, showerheads, or faulty valves as soon as possible.

Insulating exposed pipes, particularly if your system is installed outdoors, can prevent heat loss. The less heat that escapes, the less work your system has to do to maintain water temperature. That means less energy and more savings.


Maintain RegularlyOne of the easiest ways to keep costs down is by booking regular maintenance. Mineral build-up inside the system can reduce efficiency and even damage internal components. Scheduling a yearly inspection helps catch issues early and keeps your unit running smoothly. It also extends the lifespan of your system, delaying the need for costly replacements.


Use Less Hot Water Without Feeling ItChanging a few habits can go a long way. Go for shorter showers, turn off the hot tap when washing dishes by hand, and install water-saving fixtures. These tweaks are simple but effective. Some households even find value in solar-boosted systems or timers that limit hot water availability during off-peak hours.

Final Thoughts

Cutting down your hot water costs doesn't mean compromising on comfort. By choosing the right system, adjusting a few settings, and staying on top of maintenance, you can reduce energy use and enjoy a more efficient home.
