WELS Star Ratings and Water Efficiency in Australia

Understanding WELS Star Ratings and Water Efficiency in Australia

Water efficiency is a crucial aspect of sustainable living, especially in a country like Australia where water conservation is vital. The Water Efficiency Labelling and Standards (WELS) scheme helps consumers make informed choices about water-efficient products. Here’s a detailed look at how WELS star ratings work and what they mean for your water usage.

What is the WELS Scheme?

The WELS scheme is an Australian government initiative that labels products based on their water efficiency. Products such as taps, showers, toilets, urinals, dishwashers, and washing machines are tested and rated under this scheme. The more stars a product has, the more water-efficient it is.

How to Read the WELS Label

The WELS label provides essential information to help you understand a product’s water efficiency:

  1. Star Rating: Located at the top of the label, the star rating indicates the water efficiency of the product. More stars mean higher efficiency.
  2. Water Consumption Rate: The middle section shows the amount of water the product uses. This is expressed in litres per minute (L/min) for taps and showers, litres per flush for toilets and urinals, and litres per wash for dishwashers and washing machines.
  3. Product Details: At the bottom, you’ll find the registration and product information, including the company name, licence number, and model details12.

Why Water Efficiency Matters

Choosing water-efficient products can significantly reduce your water and energy bills. For example, a 6-star rated tap uses 4.5 litres per minute or less, compared to a less efficient tap that might use over 16 litres per minute3. This not only saves water but also reduces the energy needed to heat the water, leading to further savings.

Benefits of Using WELS-Rated Products

  • Cost Savings: Lower water consumption translates to reduced water bills.
  • Environmental Impact: Conserving water helps protect our natural resources and reduces the strain on water supply systems.
  • Energy Efficiency: Using less hot water means lower energy consumption, which is beneficial for both the environment and your wallet.

How to Choose the Right Product

When shopping for water-efficient products, look for the WELS label and compare the star ratings and water consumption rates. You can also check the WELS product database to verify the water rating information and ensure the product meets the required standards2.

By choosing products with higher WELS star ratings, you contribute to a more sustainable future while enjoying the benefits of reduced water and energy costs.

WELS Star Ratings FAQs

What is the WELS scheme?

The Water Efficiency Labelling and Standards (WELS) scheme is an Australian government initiative that labels products based on their water efficiency. It applies to products like taps, showers, toilets, urinals, dishwashers, and washing machines.

How do I read the WELS label?

The WELS label has three main sections:

  1. Star Rating: Indicates the water efficiency of the product. More stars mean higher efficiency.
  2. Water Consumption Rate: Shows the amount of water the product uses, expressed in litres per minute (L/min) for taps and showers, litres per flush for toilets and urinals, and litres per wash for dishwashers and washing machines.
  3. Product Details: Includes the company name, licence number, and model details.

Why should I choose WELS-rated products?

Using WELS-rated products can help you save water and reduce your utility bills. For example, a 6-star rated tap uses 4.5 litres per minute or less, compared to a less efficient tap that might use over 16 litres per minute.

How can I verify the water rating of a product?

You can check the WELS product database to verify the water rating information and ensure the product meets the required standards. This can be done on the Water Rating website.

What products are covered under the WELS scheme?

The WELS scheme covers a variety of water-consuming products, including:

  • Taps
  • Showers
  • Toilets
  • Urinals
  • Dishwashers
  • Washing machine.

How does the star rating system work?

The star rating system ranges from 1 to 6 stars, with 6 stars being the most water-efficient. The rating is based on the product’s water consumption rate, which is tested and verified by a government regulator.

Can using WELS-rated products help the environment?

Yes, using water-efficient products helps conserve water, reduces the strain on water supply systems, and lowers energy consumption, which is beneficial for the environment.

WELS Star Ratings and Water Efficiency Table

Here’s a table summarizing the WELS star ratings and their corresponding water consumption rates for taps and showers:

Table Water Efficiency

Star RatingWater Consumption (Litres per Minute)
0 StarsMore than 16 L/min
1 StarMore than 12 L/min, but not more than 16 L/min
2 StarsMore than 9 L/min, but not more than 12 L/min
3 StarsMore than 7.5 L/min, but not more than 9 L/min
4 StarsMore than 6 L/min, but not more than 7.5 L/min
5 StarsMore than 4.5 L/min, but not more than 6 L/min
6 Stars4.5 L/min or less
