The 7 most energy hungry appliances in your home

We have listed below the 8 most energy hungry appliances in your home, along with some helpful ways to reduce the amount of energy they consume


Are you struggling to get your electricity bill down, but no matter what you try it’s just not happening?  It helps to know which appliances in your home are using the most electricity.  We have listed below the 8 most energy hungry appliances in your home, along with some helpful ways to reduce the amount of energy they consume, which could have a massive impact on your electricity bill.


Air conditioning and heating

On average, heating and cooling uses by far the most energy in a typical home.  Unfortunately in many parts of Australia they are an necessity, especially here in Adelaide with our very hot summers and cold winters.  Luckily, there are a few ways you can reduce the amount of energy your air conditioner or heat uses.  If you are in the market for new heating or cooling, you have the perfect opportunity to find something that is energy efficient to use, which will save you in the long run.  Pay attention to the star rating of each unit, the higher the stars, the less energy it will use.  Inverter style air conditioners usually have the lowest energy usage.


If it’s going to be hot the next day, open up the house at night to let it cool down as much as possible, then keep the blinds and curtains closed the next day, which will keep the heat out.  In winter, keep the windows and blinds closed at night to hold the warm air inside the house, and open them up in the morning once the sun rises to let in the warm sunshine.


Hot water

Heating water is the next biggest energy user in an average house.  If you are building a house try place the hot water system as close to the wet areas as possible, which will mean the hot water doesn’t have to travel as far before it reaches the tap.  If you are searching for a new hot water unit, once again pay attention to the energy ratings.


You can cut down you hot water costs even more by reducing the temperature the water is heated to.  Between 60c and 65c is ideal, and it’s even better if you have an instant hot water system with a temperature controller.  Since heating water uses so much energy, it makes sense to also use as little hot water as is actually needed.  Keeping showers to only a few minutes (easier said than done) will make a huge difference to your energy bill.



When you think about it, hairdryers have to work quite hard, after all taking hair from wet to dry in 10 or so minutes is a big ask.  It’s a given then that hairdryers will use a fair amount of electricity.  Try letting your hair dry as much as possible before reaching for the hair dryer, even better if you can skip the hair dryer and let your hair air dry completely.


If you can’t give up the hairdryer, try using the cold setting instead.  The hot setting might use around 1500 watts of electricity, while the cold setting will only use around 75 watts, a massive difference!  If you are in the market for a new hairdryer, finding the most energy friendly model could cut your electricity bills in the long run.  I have been using this Parlux eco hairdryer for the past 6 years and it’s amazing!


Bathroom heat lamps

Heat lamps in bathroom are amazing, but that heat use a decent amount of energy to create.  Many people turn on the heat lamps with the light, so it’s a good idea to make sure the light and heat lamps are on a separate switch, and only turn on the light unless heat is needed.



Fridges and freezers are always on, but there are still ways to cut down the amount of electricity they consume.  Older fridges can use far more than newer versions, so it might be worth upgrading to a newer model if yours is getting quite old.  Be sure to take note of the energy star rating if you do decide to upgrade; the more stars the fridge has, the less electricity it will use.


Many people have at least two fridges, which is effectively going to at least double the amount of money you spending on running fridges.  It might be worth considering whether you do in fact need more than one fridge, or whether you can instead fit all of your food in the one fridge/freezer.  It could dramatically drop your bill.  Also make sure that your fridge has plenty of ventilation space around it, and routinely check that the seals are in good condition, otherwise cold air could be escaping, making the fridge work harder.


Stand by power

Keeping appliances on stand by uses way more energy than most people realise.  I experimented with switching absolutely everything off at the wall once it was not in use, and the effect it had on my electricity bill way massive (you can read about it here).


Swimming pools

Not everyone had a pool in their backyard, but many people do here in Australia.   A swimming pool pump running between four and six hours each day will cost around $1,500 every year.  To reduce this amount, use a pool cover, make sure your pump isn’t too big for the size of your pool, and consider switching to a solar powered pump.
