Choosing the most energy efficient fridge

There are many factors to consider when purchasing a new fridge. According to Energy.gov.au fridges and freezers account for around 10% of a home's energy bill1, so it's worth considering an energy efficient model that can help save on running costs. Fridges last 10-15 years so it could be worth investing in an energy efficient model that repays the up-front cost many times over its lifetime.

Energy rating

As a fridge is always on, choosing an energy efficient fridge could potentially save you more money on your bills. When shopping for a fridge for your home, make sure you check the energy star rating before making a purchase. More stars = higher energy efficiency rating which could help you save on overall running costs in the long term.

Energy consumption

Look for the energy consumption numbers on fridge labels – this tells you the expected energy use in kilowatt/hour per year so you can compare different models and choose the most energy efficient fridge.

Size

Choose the right size fridge to save energy – if it’s too big for your needs it just wastes electricity. As a general guideline, 200 to 400 litres are needed for one to two people, 520 to 600 litres for three to four people, and 700 litres for five or more people.

Style

French door fridges help you save energy because you can open one door at a time so less cold air escapes, while top-mount fridges could also help you use less energy than side-by-side fridges of the same size.

Location

Don’t put your fridge in the path of a heat source – oven, dishwasher or direct sunlight – if you do it has to work harder to stay cool. If it can only go beside a heat-generating appliance put insulation between them. Don't forget to ensure there is a 5-8 cm gap around your fridge so air can circulate.

Seals

If a fridge door is accidentally left ajar cold air escapes and more has to be created to maintain the temperature. Some energy efficient fridges have self-closing mechanisms that keep doors sealed to prevent energy waste.

Drinks access

Having a hatch or drinks door on the front gives you access to frequently used drinks without opening the door all the time so you save energy.

Ice and water dispensers

Ice and water dispensers reduce the need to open the door, helping the freezer maintain a consistent temperature more easily.

Features

Some energy efficient fridges have holiday mode, while others have temperature-regulating technology that can help you save power.

What is a star rating?

The star rating is about energy efficiency – that is, how much energy a product uses compared to similar products. More stars means more efficient, when compared to other models of a similar size and features. The more stars shown on the Energy Rating Label, the less energy the product will use and the more money you will save on your energy bills.

Most products are given between 1 and 6 stars. Technology keeps getting better as does energy efficiency! This is why nowadays you’ll see some super-efficient models in shops and online with an extra row for stars that go up to 10. For more information on how to estimate your running costs, go to the Energy Rating Website.

How to read the Energy Rating Label

In Australia, fridges and freezers are required to meet Minimum Energy Performance Standards and must carry an Energy Rating Label. The more stars, the more energy efficient. Estimated annual energy use in kilowatt hours (kWh) is displayed on the middle of the label.

FAQs

What temperature should my fridge be?

CSIRO recommends fridge compartments to be 3°C and freezers to be -18°C to -20°C2. Getting a fridge thermometer can ensure your food is kept at a safe temperature to prevent food spoilage and slow loss of food quality.

What is the lifespan of a refrigerator​?​

The lifespan of a fridge often depends on the brand, size and usage. Generally, most refrigerators can last for 10-15 years, however, proper maintenance (like regular cleaning and replacing broken parts) can help extend a fridge's lifespan.

How much energy does my refrigerator use?

The amount of energy your refrigerator can depend on a few factors like size, type and temperature setting. Smaller fridges can consume around 300kWh annually while larger fridges could consume up to 800kWh. Energyrating.gov.vic has a fridge calculator that lets you compare the running costs and energy efficiency of fridges available in Australia.
