Saving energy in the bathroom

To ensure you conserve energy in the bathroom, incorporate these practices into your routine.

Hot Water / Water Usage

  • Front loading washing machines are more energy and water efficient.
  • Minimise the duration of each shower.
  • Minimise the amount of water used in the bath.
  • Adjust your hot water temperature so that delivered hot water is no more than 50°C – you may wish to enlist the help or advice of a plumber.
  • Consider installing a water saving low-flow shower head (note: not suitable for electric instantaneous hot water systems).

Electricity / Appliances

  • Ensure the exhaust fan is used only while you are in the shower, or open a window instead.
  • Ensure bathroom heaters are used only while bathroom is in use.
  • Heated towel rails and spa baths use a lot of electricity – daily use of both could be costing you as much as $100 per quarter.

Hot water systems

Hot water accounts for approximately 25% of a home’s energy usage. Aside from the amount of hot water you use in the bathroom, laundry and kitchen, the type of hot water system you have can dramatically affect the rate at which you use energy in the home.

What sort of hot water system do you have?

  • High Efficiency Natural Gas and Load Managed Electric Off-Peak (Y6 Tariff) are the most cost effective.
  • Using Standard Efficiency Natural Gas or Electric Off-Peak (Y8 Tariff) is approximately 25% more expensive.
  • LPG hot water and Peak Tariff (GD) electric hot water systems (instantaneous and continuous reheat) are approximately 2 – 3 times more expensive to run.
  • Solar hot water systems reduce annual hot water costs on average by 60 – 65%, and could save an average family up to $165 per year – based on Standard Efficiency Natural Gas or Y8 Tariff Electric systems.
