- Take shorter showers. Use a shower timer to encourage your household to take four-minute showers.
- Wash your clothes in cold water where possible.
- Fix dripping taps.
- Insulate exposed hot water pipes with closed-cell rubber insulation, available from hardware stores.
- Service and maintain your hot water system using a licensed tradesperson according to the manufacturers instructions.
- Plan for your hot water system's replacement, especially if it's more than ten years old. Choose a hot water system to suit your household's needs.
