Energy efficient kitchen appliances

Kitchen appliances make up 25% of household energy usage, so it’s important to make smart choices when it comes to buying that new fridge, dishwasher or washing machine. Here are some tips on how to use your kitchen appliances more efficiently, and how to find the most energy efficient appliances on the market.


Keeping it cool

Fridges are top of the list when searching for energy efficient appliances. They are responsible for a massive 18% of the energy your household appliances consume. 

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%.

Set your thermostat at  5°C for the fridge and -15°C for the freezer. Each degree lower takes 5% more energy.

Put the fridge in the coolest spot in your kitchen, away from the oven, dishwasher and direct sunlight.

Which fridge should I buy?
Fridges are among the few kitchen appliances that come with energy star ratings. Most fridges are only rated between two and three stars, but there are a few with four-star ratings.

LG’s GN-450UWL and GT-442BWL models are medium-sized, four-star fridges that consume about 340 kWh/year. Samsung’s four-star SRL455DLS and SRL458ELS models are large fridges, yet consume only 330 kWh/year.

What’s cooking?

The kitchen appliances you use for cooking account for 15% of your household appliances’ energy consumption.

Slow cookers are the shining stars among energy efficient appliances. They only require the energy of a light bulb to cook an entire meal.

Choose a convection microwave over an ordinary microwave, and a fan-forced oven with triple glazed doors and excellent insulation. On the cooktop, gas is more efficient than electric, while an induction element can boil a pot of water 50% faster than the average electric stove.

Cooking appliances don’t come with energy star ratings. Use Choice’s comparison review tables to compare the amount of energy each model requires. Sharp’s R60A0S microwave uses just 0.08 kWh to reheat a meal. Kambrook’s KMO400 microwave uses just 4.9 kWh/year on standby, while other models use up to a massive 36.83 kWh/year.

The 10-year running costs of duel fuel ovens start with Technika’s TEG64U at $272 but can be as high as $709. Miele’s H 2661 B CleanSteel wall oven costs $202 over ten years, while other wall ovens cost double this amount.

Wash the dishes, dry the dishes

You may think the most energy efficient method of washing and drying your dishes is the old-fashioned kitchen sink. But households without dishwashers use 31 litres of water a day rinsing and washing up.

Dishwashers, on the other hand, use about 10 litres. They account for 2% of household appliances’ energy consumption, though, so it’s important to buy a dishwasher with a high energy efficiency rating. Consider a hot water connection during any kitchen renovations too, especially if you have solar hot water.

Dishwashers have energy star ratings, but not all top-rated dishwashers are energy efficient on the ‘normal’ cycle. Choice tests dishwashers on the normal cycle and gives them an energy efficiency score.

Surprisingly, Choice’s top three energy efficient dishwasher models – Asko D5434WH, Baumatic BDWI660 and Samsung DW5343TGBWQ – are all rated just 3.5 stars.
