Save money on your hot water usage with these energy-saving tips and Government rebates
You’re probably noticing the rising cost of electricity and looking for realistic ways to reduce everyday household expenses. Below are practical, achievable steps that can make a real difference to your hot water usage, system efficiency and overall energy bills.
Tip 1 — Reduce your household’s hot water usage
Small day-to-day habits can have a big impact on your hot water costs. Being mindful about how and when you use hot water is often the easiest place to start.
Turn off taps when not in use
Even short bursts of running hot water add up over weeks and months. Turning taps off when rinsing dishes, brushing teeth or washing hands can noticeably reduce consumption.
Install reliable low-flow fittings
High-quality low-flow showerheads and tap aerators, such as those from Methven, reduce water use without compromising comfort. Cheaper fittings can cause temperature fluctuations, while good ones deliver a consistent, enjoyable shower and help lower your energy usage.
Wash laundry in warm or cold water
Modern washing machines clean effectively without needing hot water for most loads, cutting down unnecessary hot water usage.
Avoid using multiple hot water outlets simultaneously
Running showers, dishwashers and washing machines at the same time puts unnecessary strain on your water heater. Instead of saving energy, it forces the system to work harder and depletes the stored hot water more quickly. Spreading out usage throughout the day helps keep your system running efficiently and prolongs its lifespan.
Thermostat considerations
Storage hot water systems must stay between 60°C and 70°C for safety and to prevent Legionella.
Instantaneous/continuous flow systems can be set lower, around 50°C, because they heat water on demand rather than storing it.

Additional insulation is usually unnecessary
Northern Beaches homes generally do not experience the cold temperatures that would require extra insulation wraps. Modern systems already include quality built-in insulation, so additional jackets rarely provide any benefit in this climate.
Look out for leaks
Even a slow drip increases energy costs because your system constantly reheats lost water. Contact us promptly if you notice unusual water usage.

Tip 2 — Consider upgrading to an energy-efficient hot water system
If your system is old, unreliable or expensive to run, replacing it with a modern, energy-efficient unit (especially a heat pump) can dramatically lower long-term costs.
Heat pumps use far less electricity than traditional electric or gas systems and are becoming one of the most cost-effective choices for households looking to reduce their bills.
Generous Government rebates and incentives are still available for Northern Beaches residents. These rebates are typically applied upfront as an installation discount, reducing your out-of-pocket expenses. In some cases, additional Federal rebates may apply.
Call 0410 693 532 to check which rebates you may be eligible for. We monitor all current incentives and can recommend the most suitable upgrade for your home.

Tip 3 — Turn off your water heater when travelling
If you’re heading away, especially for several weeks, turning off your hot water system can reduce unnecessary running costs and minimise the risk of leaks while the house is empty.
Here are the key things to consider:
How long you’ll be away
Extended holidays are the most beneficial times to switch off the heater.
Age of the system
Systems older than 10 years are more prone to leaks or failure. Switching them off before travelling is a wise precaution.
Location of the unit
Indoor units can cause significant damage if they fail while no one is home. In these cases, turning the system off is highly recommended.
Type of pipework
Systems connected with flexible braided hoses are more likely to fail. If your unit has these, it’s safer to turn it off before you leave.
If you’re unsure, we can provide advice based on your system and home.

Tip 4 — Keep your water heater running efficiently with simple DIY checks
Regular visual checks can help you catch minor issues early and keep your system performing well.
Look for leaks
Inspect the tank, valves and pipe connections for moisture or corrosion.
Test the pressure relief valve
Lift the valve lever gently to ensure water flows freely for 10 seconds. If it sticks or doesn’t operate smoothly, the valve may need replacement.
Monitor water temperature
Fluctuating temperatures or water running out faster than normal can indicate developing issues.
Watch for ants
Ants sometimes nest around outdoor systems and can interfere with electrical parts.
Clear the area
Ensure grass, soil and debris are cleared from around the base to prevent moisture retention and rust.
If you notice anything out of the ordinary, reach out for support.

Tip 5 — Ensure your hot water system is serviced regularly
Hot water systems work every day, often without attention, until something goes wrong. Regular servicing is essential for reliable performance and lower energy usage.
If it has been more than five years since your last service, it’s time to schedule a check-up. A professional inspection can:
- Identify hidden leaks
- Improve efficiency
- Reduce energy wastage
- Extend the lifespan of your water heater
A well-maintained system operates more efficiently and often reduces long-term running costs.
