Appliances

Our homes are equipped with a number of appliances, all of which make life easier and more comfortable. However, using them consumes energy; we can reduce the amount of electricity we consume, while using appliances, by up to 15% with just a few simple tips.

The most energy-hungry appliances in our homes are:

  1. Water heaters
  2. Washing machines / clothes dryers
  3. Fridges and freezers

Residential water heaters range in capacity from 30 litres to 150 litres, with ratings of 1.2 kW to 1.5 kW. This means that when the heating element inside the water heater is on, it uses 1.2 kW to 1.5 kW per hour depending on its capacity. The most important factor is the thermostat setting. 

To understand how much it costs to operate water heaters, let’s consider a 1.5 kW water heater running for 1 hour (i.e. the heating element is on for 1 hour):

Cost of running a 1.5 kWh water heater per month:

Amount of electricity consumed will be (1.5 kW x 1 hr/day x 30.5 days/month) = 45.75 kWh/month

Unit cost of electricity is shown in the following table:

For the calculations below, we use the example of an expat villa without accounting for any other electricity use. It is intended to give you a general idea. Your results may vary.

Cost per month = 45.75 kWh/month x AED 0.21/kWh = AED 9.61/month

 

Power tip intext 1  Fact:  Did you know that for every hour that the heating element in your water heater is not on you can save up to approximately AED 10/month? This is just for one water heater. Multiply that amount by all the water heaters in your home and imagine the savings! Better yet, imagine the savings if you turned off all of your water heaters except for the few hours per day you need them.

 

How to Save on Your Water Heater Consumption

There are few simple measures that you can take to help reduce your water heater electricity consumption. We have highlighted these measures below: 

Measures: 

  • Only heat water when needed. This can be accomplished by turning the water heater on half an hour prior to use.
  • Consider using a timer; you can heat water at a set time every day, eliminating the need to turn off the water heater manually.
  • Consider adjusting your water heater’s thermostat down to 55°C. Most people don't need water hotter than that and every 2 degrees lower uses up to 6% less electricity.

Most washing machines give us the option to select between hot or warm or cold water to wash our clothes. Although the use of hot water will potentially give the best cleaning results, it consumes a lot of electricity and isn’t really necessary. Keep in mind that not all your clothes require cleaning with hot water. In fact, the majority of your clothes can be cleaned effectively using water that is either cold or warm. Running a cold wash uses almost one quarter the energy required for a warm wash cycle.

Monthly cost of running a 1.2 kWh washing machine 1 hour every day:

Amount of energy consumed by running a 1.2 kWh washing machine for an hour every day = (1.2 kW x 1 hr/day x 30.5 days/month) = 36.6 kWh/month

Unit cost of electricity is shown in the following table:

Cost per month = 36.6 kWh/month x AED 0.21/kWh = AED 7.69/month

How to Save on Your Washing Machine Consumption

There are few simple measures that we can all take to easily help reduce our washing machine electricity consumption. We have highlighted some of these measures below.  

Measures: 

  • To ensure optimal performance and avoid wasting unnecessary electricity and water, always wash with full loads whenever possible. Never overload your washing machine.
  • Use lower temperature settings. Use warm water or cold water for the wash cycle instead of hot water.
  • Experiment with different laundry detergents to find one that works well with cooler water.
  • Buy a 5-star energy-efficient washing machine.

Refrigerators are considered one of the most-used home appliances. They vary in size and ratings and the larger a refrigerator, the more electricity it consumes. For example, a double-door refrigerator consumes a lot more than a small one.

Every time we open the refrigerator door, we allow cold air to escape, and this prompts the refrigerator’s compressor to start up in order to maintain the set temperature. Every time the compressor is on, the refrigerator consumes electricity and costs you money.

 

Power tip intext 1  Fact 1:  Did you know that estimates show that approximately 7% of the energy used by refrigerators is due to opening its doors?

 

How to Save on Your Refrigerator Consumption

There are some measures that we can all take to easily help reduce our refrigerator electricity consumption. Some of these measures are given below.  

Measures: 

  • The older your refrigerator is, the more inefficient it is likely to be. If your refrigerator is 15 years or older, you should definitely think about changing it.
  • You should never put warm or hot food into the fridge as this will make the fridge work extra hard to try and keep it cold. Always allow food to cool down first. It is also better food safety practice to allow food to cool before refrigerating it.
  • Don’t leave the fridge door open any longer than absolutely necessary. Leaving it open will allow the cold to escape and the fridge will then have to use more energy to cool down again.
  • Remember to regularly defrost manual-defrost refrigerators and freezers.
  • Buy an energy-efficient refrigerator.
  • Buy a refrigerator that is suitable for your use. For example, if you are a single person, who doesn’t cook very often, then you may only require a small refrigerator.
  • It is more energy efficient to purchase one large fridge rather than two smaller units.
  • Make sure your refrigerator door seals are airtight. An easy way to tell if the door seals are in good condition is to conduct the following test:
    Close the door on a piece of paper that is half in/half sticking out. If you can easily slip the paper out, the seal may need replacing, or it may be time for a new unit altogether.
  • The location of your fridge can make a difference in how energy efficient it is. Make sure it is out of direct sunlight and not close to the oven.
  • It is best to keep the refrigerator against an outside wall so that the heat it generates can escape easily, and always make sure that there is a little space all around the unit so that air can circulate easily.


Power tip intext 1  Fact 2: Did you know that refrigerators set 10 degrees lower than needed or freezers set 5 degrees lower than needed can increase energy use by as much as 25%?

 

Power tip intext 1  Fact 3: Did you know that allowing frost to build up more than a quarter of an inch will make your freezer run less efficiently?
