74. WELS & The Energy Rating Label - Water Efficiency Labelling and Standards (WELS) Scheme - Cost Savings

Using water efficient products could save Australians more than $2 billion by 2030. That’s an average saving of $175 â€‹per household each year. 65% of these savings are from reduced electricity and gas costs from avoided water heating. 35% of these savings are from reduced water bills. The below table compiled by our contemporary residential designers in the Northern Beaches shows where in the household these savings can be made.

  • 4-star shower that flows at 6L/min will save 105kL and $315 each year
  • Figures based on replacing a 15L/m shower. An equivalent amount (or more) each year on energy could be saved because less water will be heated.
