One of the best ways to save both water and energy is to install an efficient showerhead. Water saving showerheads can be easily fitted to existing shower arms.
- an inefficient showerhead uses about 15 to 25 litres of water per minute - a three star rated water efficient showerhead uses as little as 6 or 7 litres per minute.
- an inefficient showerhead uses at least 120 litres of water per eight-minute shower whereas a water efficient model uses less than 72 litres or 40 per cent less water
- with a water-efficient showerhead, gas hot water costs will reduce by approx. 47%
All showerheads sold in Australia have at least a WELS 3-star rating.
To find out the water consumption of showers by star-rating and brand, use the WELS Product Search.
Tenants can ask your landlord to replace the showerhead. Alternatively, you could replace the showerhead themselves, keeping the original one to re-install when they move out and taking the efficient one with them.
Check flow rates of your showerheads
You can easily check your shower’s flow rate to determine if it’s water-efficient.
If there’s no rate written on the showerhead you can measure the flow rate by turning on the shower at its normal rate for 30 seconds and capturing the water in a bucket. Measure how many litres of water are in the bucket and double the figure to get the flow rate.
Inefficient showerheads can use more than 15 litres per minute or more. A WELS 4-star rated showerhead uses 7 litres per minute. These volumes of water require heating — so the more efficient the showerhead, the less energy you’ll need to heat the volume of water.
