Using hot water is the second biggest consumer of energy in Canberra households, accounting for 16% of total energy use. There are a number of ways you can reduce your hot water energy use, and help out the environment.
Focus on the shower
- Use a timer and try spending no more than three to five minutes in the shower
- Replace inefficient shower heads
Wash clothes in cold water
- If your clothes are very dirty, soak them in detergent in a bucket before you wash them
Reduce tap use
- Turn off the tap while you’re brushing your teeth, shaving or washing your face
- Turn mixer taps all the way to the cold side, so you don’t use unnecessary hot water
- Repair any leaking taps
- Use water-saving features, such as tap aerators and flow restrictors
Reduce the temperature of your hot water system
- Reduce the temperature of your hot water storage tank to 60 degrees
- If you have an instantaneous hot water system, ensure the thermostat is no higher than 50 degrees
When you use hot water to wash your clothes, 90% of your energy costs will be to heat the water and 10% to wash your clothes.
