What You'll Learn
Dryers use more energy than washing machines
There are several reasons why dryers use more energy than washing machines. Firstly, the drying process itself requires a significant amount of energy to generate heat and circulate air. Secondly, dryers often run for longer periods than washing machines, especially if the load is heavy. Thirdly, older dryer models with worn parts tend to consume more electricity than newer models.
To reduce energy consumption when using a dryer, there are several steps you can take. Firstly, try to dry your clothes on a lower heat setting and opt for a longer drying time instead. This will help you use less energy overall. Additionally, remember to clean the lint trap regularly, as dirty lint traps block airflow, causing the dryer fans to work harder and consume more electricity.
Another way to reduce energy consumption is to opt for a ventless dryer, which uses heat-pump technology to recycle hot air within the machine, resulting in lower energy usage per cycle. Alternatively, you can choose to air-dry your clothes, especially during the summer months when electricity prices tend to be higher.

Factors affecting energy efficiency
Several factors affect the energy efficiency of washing machines and dryers. Firstly, the type of machine is a significant factor. Front-loading machines are generally more energy-efficient than top-loading ones, as they use less water and require less power to operate. ENERGY STAR-certified front-load washers, for instance, use approximately 45% less energy and 50% less water than top-load agitator washers. Top-load impeller washers are also a more energy-efficient option compared to traditional top-load washers.
Secondly, the presence of energy-efficient technology and features can make a difference. ENERGY STAR-certified washers, for example, incorporate advanced features that result in 25% less energy consumption and 33% less water usage. These machines use sophisticated wash systems that are gentler on clothes and can handle hand-washables, increasing their efficiency. Additionally, smart washer-dryers can help monitor and control energy consumption through dedicated apps, providing suggestions for improving laundry habits.
Thirdly, the wash cycle and water temperature play a role in energy efficiency. Selecting the appropriate wash cycle for the laundry is essential, reserving hot water cycles for heavily soiled items and using cold water for regular loads. Cold water washes can significantly reduce energy consumption. Running full loads is also more energy-efficient than multiple small loads, although overloading the machine should be avoided as it can decrease efficiency.
Lastly, the frequency of use impacts energy efficiency. The more frequently a machine is used, the higher the energy costs. For example, using a dryer every day for a year will result in higher electricity costs than using it only once a week. Similarly, washing machines used daily will incur higher costs than those used weekly. Thus, reducing the usage frequency of these appliances can lead to significant energy and cost savings.
Other factors that can contribute to energy efficiency include proper maintenance of the machine, including regular cleaning of the lint filter, and choosing the right time of day to operate the appliances, as electricity costs vary at different times.

Energy-saving tips
A washer-dryer is a convenient solution if you don't have much space or time for laundry. However, it's important to note that it can significantly contribute to your energy consumption and bills. Here are some energy-saving tips to help you optimise your washer-dryer usage:
Wash with Cold Water
Switching from warm or hot water to cold water can reduce energy usage by up to 50%, according to ENERGY STAR®. This is because water heating accounts for about 90% of the energy used by a washing machine. Using cold water detergent can ensure your clothes still get a thorough clean.
Wash Full Loads
Your washing machine will use the same amount of energy regardless of the load size. Therefore, it's more energy-efficient to wait until you have a full load to wash. Remember to separate heavier items like towels and cottons from lighter-weight clothing to avoid overloading the machine.
Use High-Speed Spin Cycles
High-speed or extended spin cycles remove more moisture from your clothes before they go into the dryer, reducing the time needed for drying. This not only saves energy but also reduces wear and tear on your clothing.
Make Use of the "Cool Down" Cycle"
If your dryer has a "cool down" cycle, utilise it! This setting allows your clothes to finish drying using the remaining heat in the machine, reducing the overall energy used.
Opt for a Smart Washer-Dryer
Smart washer-dryers, such as Candy's, can help you monitor and manage your energy consumption. Through connected apps, they can suggest the best programs and provide insights to improve your laundry habits.
Time Your Laundry
If possible, do your laundry during off-peak hours when electricity costs are lower, typically from 7 pm to 8 am. This way, you can save money on your energy bills.
Choose an Energy-Efficient Machine
When purchasing a new washer-dryer, look for the ENERGY STAR® label. These machines use about 20% less energy than conventional models. For even greater energy savings, consider a heat pump dryer, which can be up to 60% more efficient than traditional dryers.
Air-Dry Your Clothes
Consider air-drying your clothes on a clothesline or rack whenever possible. This is an excellent way to save energy and prolong the lifespan of your garments.
By implementing these energy-saving tips, you can optimise your washer-dryer usage, reduce your environmental impact, and lower your utility bills.
