Whitegoods energy saving tips

Fridge and freezer

  • Choose an energy efficient model by comparing the star ratings.
  • Newer, high efficiency refrigerators use half as much energy as older models, so they cost half as much to run.
  • Fridge/freezer combinations with the freezer on the bottom are typically more energy efficient than freezer on top.
  • If you're not keeping a fridge at least two-thirds full or a freezer at least three quarters full, it's too big and therefore costing you more money to run.
  • Keep your refrigerator at constant temperatures, and use a thermometer to help you accurately set temperatures:
    • fridges = 3 to 4°C
    • freezers = -15 to -18°C
  • Defrost your freezer every six months or when there is a one-centimetre frost build up.
  • A refrigerator that is not level may cause the door gasket to seal improperly, letting cold air leak out. Adjust the legs until the refrigerator is level.
  • Make sure the door seal is tight and free from gaps. Replace door seals if they are not sealing properly, cracked, or you feel cold air leaking out. To test for tightness, close the door on a piece of paper and try to pull it out. If it slides out easily, so does air.
  • Freezers operate most efficiently when they are full. To help retain the cold temperature when the freezer is less full, freeze jugs of water. Also, more cold air spills out when you open the door if the freezer is nearly empty.
  • In freezers, food packages should be scattered and should never be grouped or stacked together until they are completely frozen.
  • The more air space in a fridge, the more power it will use to keep that air space cool. Refrigerators operate efficiently when full. Also, more cold air spills out when you open the door if the refrigerator is nearly empty. A good idea is to fill air spaces with containers of water, but not overloaded, overloading prevents cold air from circulating properly.
  • To ensure proper cooling, don't crowd food items. Too many things may obstruct air circulation.
  • Don't put hot foods into fridge/freezer, allow food to cool down.
  • Choose a cool position, place refrigerator/freezer away from direct sunlight or an oven.
  • Leave an area around and above the fridge and freezer for ventilation.
  • Keep the fridge and freezer condenser coils at rear free from fluff.
  • Do not open the deep freezer or refrigerator door too often, think ahead and plan what you need to take out.
  • Keep refrigerator and freezer organised so that the door isn’t kept open while searching for items.
  • Paper is an insulator – replace paper wrappings on food items with aluminium foil or plastic wrap.
  • If you have two fridges/freezers, fill one of them up and turn the other off if possible.
  • If you will be gone for an extended period of time, consider cleaning out your refrigerator, unplugging it and leaving the doors open.
  • Upright freezers cost more to run than chest models because more cold air escapes.
  • Self-defrost models use much more energy than non-defrost models.
  • Cover liquids and wrap foods stored in the refrigerator. Uncovered foods release moisture and make the compressor work harder.
  • Automatic ice-makers and through-the-door dispensers will increase both the energy use and the purchase price.

Dishwashers

  • Choose an energy efficient model by comparing the star ratings.
  • Dishwashers use between 25 and 80 litres of water per full cycle, which can often be less water than washing up in a sink 3 times a day.
  • Run the machine only when it's full.
  • Don't rinse dishes in hot running water before you put them in dishwasher.
  • Use the setting with the lowest temperature or the shortest running time – if it gives you a satisfactory result.

Washing machine and dryer

  • Choose an energy efficient model by comparing the star ratings.
  • Use the sun to dry clothes whenever you can.
  • Wash clothes in cold water with coldwater laundry detergent.
  • Load your washer fully each time. If you do an extra wash you'll be using more power.
  • Adjust the water level of your machine when you only have a small load.
  • Don't put soaking wet clothes in the dryer.
  • Don't over dry clothes.
  • Clean clothes dryers filter regularly – it speeds up the drying time, as well as being safer.
  • Don't overfill the dryer.
  • Choose a clothes dryer that turns off automatically as soon as the clothes are dry.
  • Dry consecutive loads as the residual heat will help dry the next load.
  • Front-loading washing machines are up to 15% more energy efficient than top loading machines.
