Washing machines are a staple in most households, offering convenience and efficiency for one of life’s unavoidable chores. However, this convenience comes with a cost. Washing machines are among the most energy-consuming appliances in your home, and their frequent use can significantly drive up your electricity bill. But what if there was a simple adjustment you could make to drastically reduce this expense? Surprisingly, the answer lies in a small, often-overlooked feature: the temperature control button.
The Hidden Button That Saves Energy
Every washing machine is equipped with a temperature control button or setting, though its location can vary depending on the model. This button allows users to select the water temperature for each wash cycle. Despite being a standard feature, it’s often ignored because many people simply stick to the default setting, which is usually set to 40°C (104°F). This temperature setting is chosen because it’s effective at removing stains and sanitizing clothes, but it comes at a steep energy cost.
Heating water accounts for the majority of the energy a washing machine consumes during each cycle. The higher the temperature, the more energy is required to heat the water. Thankfully, reducing this setting is not only easy but also incredibly effective in cutting down your energy usage.
The Viral Energy-Saving Tip
Recently, Ms. Beth, a mother of two from the UK, shared her simple yet impactful energy-saving tip on social media. She pointed out that most washing machines default to 40°C (104°F), but washing at such a high temperature isn’t always necessary. Beth recommends lowering the temperature setting to 20°C (68°F) for most laundry loads.
By doing this, she claims you can save up to 62% on energy costs per load. This is because the washing machine no longer needs to expend significant energy heating the water to a higher temperature. For households that run multiple loads of laundry each week, this small adjustment can add up to substantial savings over time.
Does Washing at Lower Temperatures Still Clean Effectively?
One common concern about washing clothes in cold water is whether they’ll come out clean. Fortunately, modern detergents are specifically formulated to work efficiently in cold water. These detergents dissolve well, penetrate fabric fibers, and lift away dirt and stains even at 20°C (68°F).
Cleaning experts confirm that most daily laundry—like lightly soiled clothes, shirts, pants, and linens—can be effectively washed in cold water. There are exceptions, of course. Hot water is still recommended for heavily soiled items, grease stains, or bedding and towels that need to be sanitized. However, for your everyday laundry needs, cold water is more than sufficient.
How Much Can You Actually Save?
Energy efficiency experts and electronics manufacturers agree that reducing the temperature from 40°C to 20°C can cut washing machine energy consumption by as much as 62% per cycle. Over a year, this can translate into hundreds of dollars in savings, depending on how frequently you run your washing machine.
For example:
- Washing 4 loads per week at 40°C could cost around $150-$200 annually in electricity.
- Dropping the temperature to 20°C could reduce that cost to around $60-$80 annually.
These numbers will vary depending on electricity rates in your area, but the savings remain significant across the board.
How to Adjust Your Washing Machine Temperature Setting
Switching your washing machine to a lower temperature setting is incredibly simple. Here’s how you can do it:
- Locate the Temperature Control Button or Dial: Look for a button or dial labeled “Temp,” “Temperature,” or a symbol showing a thermometer.
- Adjust the Setting to 20°C (68°F): Rotate the dial or press the button until it displays 20°C. Some machines might also have a “Cold Wash” option.
- Choose the Right Detergent: Use a detergent specifically formulated for cold water washing to ensure optimal performance.
- Start the Wash Cycle: Load your clothes, add detergent, and run the machine as usual.
Some newer washing machines also come with an Eco Mode or Energy-Saving Setting. These modes are specifically designed to reduce water heating and optimize energy efficiency.
When to Use Hot Water Instead
While washing at 20°C is ideal for most everyday laundry, there are certain situations where hot water is still the better choice:
- Heavily Soiled Clothes: Items stained with grease, mud, or stubborn grime.
- Sanitizing Bedding or Towels: After illness, hot water helps kill bacteria and germs.
- Removing Certain Stains: Some stains respond better to hot water treatment.
For these special cases, it’s fine to increase the temperature, but keep in mind that these situations are exceptions, not the rule.
Environmental and Longevity Benefits
Lowering your washing machine’s water temperature isn’t just good for your wallet—it’s also beneficial for the environment. Reduced energy consumption means lower carbon emissions, contributing to a greener planet. Additionally, washing at lower temperatures places less stress on your washing machine’s heating element, extending the appliance’s lifespan and reducing the risk of costly repairs.
Final Thoughts: Small Change, Big Results
Sometimes, the simplest solutions can have the most significant impact. Adjusting your washing machine’s temperature setting from 40°C to 20°C is a small change that delivers major benefits. With energy savings of up to 65%, lower electricity bills, and a reduced environmental footprint, it’s a win-win scenario for any household.
So, the next time you’re about to start a load of laundry, don’t just press “Start” without thinking. Take a moment to adjust your temperature settings. Your wallet—and the planet—will thank you for it.
