Heat water efficiently

Water heating makes up around a third of your household energy bills. This means that you can make some serious savings by being smart with how you heat and use hot water.

Use hot water wisely

Being smart about how you use hot water will save you energy and money. Check out our tips for simple changes you can make to the way you use hot water, that will make a difference over time.

• Use a cold wash more often — A hot water clothes wash can use almost 10 times more electricity than a cold wash. Switching to cold water can save you around 25c per wash.
• Turn off the tap — Fill the sink with hot water instead of leaving the tap running when doing things like shaving.
• Shower rather than bath — Showers typically use half as much water and energy, and cost half as much.
• Time your showers — Cutting your shower time from 15 minutes to 5 minutes can save you around 66c per shower – that’s around $5 per person per week.
• Fill the dishwasher — Only run full loads in the dishwasher and washing machine. Use the eco setting on your dishwasher if it has one. Pre-rinse dishes if required, in cold water.
