Around a third of the energy used in an average South Australian home goes on heating water (see the Australian Government's Greenhouse website: Your Home - Hot Water Service - new window).

By reducing your hot water use you'll save water, save energy and save money!

	Does your hot water system have a temperature control? For instantaneous hot water systems, look for a temperature dial on the system and, if there is one, turn down the temperature to 60°C, or 50°C. The Department of Health requires that storage hot water systems are set at or above 60°C, but instantaneous systems can be set at 50°C. For hot water systems with storage tanks, the water in the tank must be at least 60°C to control Legionella bacteria.
	Consider installing a AAA AAA rated water efficient shower head. On average, showering uses the most hot water in the majority of South Australian homes. Using a water efficient showerhead will save you considerable energy, water and dollars. Visit the Federal Government's Water Rating (new window) website for more details.
	Switch from electrical water storage heating to an electrical heat pump, gas heater or, even better, use the natural heat from the sun with a gas boosted solar hot-water system. If you live in Adelaide the sun can contribute 60-70% of your hot water. Information on rebates for installing a solar hot-water system (new window) can be found on the Energy Division's website.

• Take shorter showers.
• Turn off the hot-water system when you go away for more than a couple of days.
• Use at least 10mm of insulation around external hot water pipes to reduce heat losses, especially for the first few metres from your hot water system.
