A fridge is the single biggest power consumer in many households, because nearly all households have at least one fridge and they run for 24 hours a day. On average, 13 per cent of Victorian household energy costs are spent on running refrigeration.
Choose an efficient fridge or freezer
Compare star ratings
The energy rating label helps you compare the energy efficiency and running costs of different fridges and freezers. Labels display a rating from 1 to 6 stars, but super-efficient models can receive 7 to 10 stars, with the additional stars displayed as a crown on top of the label. The more stars, the more energy efficient the fridge or freezer will be, and the lower the running costs.
Compare the energy efficiency of different models, using the star rating system, then use the numbers in the energy consumption box to find out the model's annual energy consumption. If you know your electricity tariff, you can then estimate what your annual running costs will be using the Energy Rating Calculator.
When it's time to buy a new fridge or freezer, replace your old one with the most energy efficient model that will suit your household's needs. Try to buy a two-door fridge with at least 2.5 stars, a chest freezer with at least 3 stars, or an upright freezer with at least 2.5 stars. Every extra star will reduce your running costs by around 20 per cent.
Choose your fridge/freezer wisely
- Choose the right size: If your current fridge is usually less than two-thirds full, it is probably too big for your needs. Consider a smaller version.
- Look for models with door alarms: Door alarms will remind you to close the fridge or freezer door quickly.
- Thermostat controls: Buy a model with thermostat controls that are easy to read and use.
- Two-door fridges: If you are shopping around for a two-door fridge, choose a model with the freezer on top, as these models generally consume less energy than those with the freezer at the bottom.
- Chest freezers: Consider buying a chest freezer rather than an upright freezer. Chest freezers are generally more efficient because cold air doesn't spill out when the door is opened.
- Check the energy consumption box: Remember that models with built-in icemakers tend to use more energy. Refer to the energy consumption box on the energy rating label to see what the annual electricity use will be.
- Look for brands that are designed for recycling: recycling whitegoods will reduce landfill, conserve resources and reduce the amount of greenhouse gases created in the production of new materials.
Running costs for fridges and freezers
The table below provides estimated running costs for different types of fridges and freezers based on star rating and volume.
|Volume (litres)||Energy star rating||Annual running cost*||Energy use (kWh/yr)||Annual GHG emissions (kg)**|
|2-door frost-free fridge|
* Calculations assume an electricity tariff of 31.9c/kWh, based on a typical Melbourne tariff. This does not include any pay-on-time discount, which would reduce the amount paid.
** GHG = Greenhouse gas emissions, expressed in kg of carbon dioxide equivalent. A greenhouse coefficient of 1.18 kilograms per kilowatt hour of electricity has been used.
Use your fridge and freezer efficiently
Regardless of the type of fridge and freezer you own, you can reduce your energy bills by running your machine efficiently:
- Location: Fridges and freezers should be located in a cool and well-ventilated space, with a gap of at least 5cm around the appliance for ventilation and heat dispersal.
- Temperature: Set the thermostat at 3ºC for the fresh food compartment and -18ºC for the freezer compartment.
- Door opening: Don’t open doors too frequently or for too long. Every time the door is opened cold air is released and warm air flows in.
- Stocking: Don't overfill your fridge or freezer, as this will interfere with the circulation of cold air.
- Door seals: Keep door seals clean and replace damaged seals.
- Defrosting: Regularly defrost fridges and freezers if they don’t automatically defrost.
- Coils: Keep any coils at the back of the fridge free of dust, as dust on coils can have an unwanted insulating effect and force your fridge to use more energy than necessary.
- Second fridge: If you have a second fridge that you only use on special occasions, it is better to turn if off for most of the year and only turn it back on as needed.
Dispose of your whitegoods responsibly
Ensure that when you buy a new product to replace an old one, you take the necessary steps to dispose of your old product responsibly. Recycling whitegoods will reduce landfill, conserve resources and reduce the amount of greenhouse gases created in the production of new materials.
