Water Saving Shower Head – Save Money, Water & Energy
A water saving shower head (WELS 3 star rated) uses 9 litres per minute or less. Using a water saving shower head, a family of four annual water savings² can be as much as 221,000 litres and $660 per year.
Showers use the most hot water in a typical home, with a standard shower head using 15 – 25 litres per minute. If you want to conserve water, replacing your old shower head with a water saving shower head can make a big difference. By choosing the right shower head, you can drastically reduce your water consumption but still enjoy your shower.
With a water saving shower head and very little effort or investment you could be saving money on hot water running costs, water usage & the cost of gas or electricity for hot water.
So, how do you do it?
The use of a water saving shower head and taps is the answer. WELS is Australia’s Water Efficiency Labelling and Standards scheme.
The scheme helps consumers make informed decisions, when buying water-using products, to help them save water and money.
Water Saving Shower Head – Saving² up to $660 and 221,000 Annually
A 3-star water saving shower head uses 9 litres per minute or less. A family of 4 could save $315 per year¹ or more on their water bills and 105,000 litres of water or more with a water saving shower head. And that doesn’t even include the electricity or gas savings on the hot water.
In the best case scenario, a family of four annual water savings² can be as much as 221,000 litres and $660, based on switching from a 25L/min to 6L/min water saving shower head. This also doesn’t include the electricity or gas savings on the hot water.
For reference, a family of four will save* about $35 per year and 12,000 litres of water for each 1L/min reduction in water use.
A water saving shower head is the quickest way to save water in your home. Showers use the most hot water in a home, so switching to water efficient water saving shower head is just common sense.
A standard showerhead uses about 15 to 25 litres of water per minute, while a WELS 3 Star rated water efficient water saving shower head uses a maximum of 9L/min.
The results are even better with a WELS 4 Star rated unit, with a maximum of 6L/min.
So, assuming an 8 minute shower, a standard showerhead uses 120 to 200 litres of water whereas a water saving shower head uses between 48 and 72 litres, or 40 to 75% per cent less water.
¹Assume switching from 15L/min to a 4 Star 6L/min shower head with daily 8 minute showers for a family of four and a $2.99/kL average water price based on the national average price reported by the ABS for 2014–15*.
²Assume switching from 25L/min to a 4 Star 6L/min shower head with daily 8 minute showers for a family of four and a $2.99/kL average water price based on the national average price reported by the ABS for 2014–15*.
Saving Energy and Money with WELS Water Saving Shower Head
People generally shower for 5 to 10 minutes. Assuming you have a 3 Star water saving shower head and you mix in some cold water with the hot, the typical hot water consumption would probably be in the 7L/min range.
If you also assume an 8 minute shower, you will consume about 56 litres of hot water per shower or a family of four would consume 224 litres versus.
That same family would use as much as 640 litres of hot water with a standard showerhead, assuming 20L/min consumption.
The use of WELS 3 star rated water saving shower head is an important factor in saving energy, as hot water typically accounts for about 25% of the average home energy costs.
Your actual savings depend on the type, size and energy efficiency rating of the hot water system you currently own.
You can also save money on the purchase price of a new hot water system, as the WELS water saving shower head help reduce the size and cost of the hot water system required.
If you also choose a 5 Star or better hot water systems, you will further minimise your hot water energy costs

Saving with WELS Taps & Water Saving Shower Head
You can also save money, energy and water by using more efficient tap fixtures, in addition to water saving shower head.
Before purchasing a new tap, check the WELS star rating.
The higher the rating, the more efficient the model.
Your family’s annual water savings could be as much as 25,000 to 35,000 litres.
The range is based on a comparison between 0 Star (16L/min), 3 Star (8.25L/min), 4 Star (6.75L/min) and 5 Star (5.25L/min) kitchen or bathroom taps.
Once again, you can save energy and money, too. Annual energy savings can be up to $297 per year*.
To save even more, make sure you fix all leaks and avoid unnecessarily running taps when washing, shaving or brushing your teeth.
