Hot water

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.
