Wash with a cold cycle
This is the easiest way to reduce electricity use, regardless of kind of washing machine you have. Washing with a cold cycle can save you more than 80% of your energy consumption and cost. This is because most of the energy is used just to heat up the water in warm washes.
The answer to when to do laundry to save money
Take a look at your energy account and check your tariff rate. Most people will see that they have a lower tariff overnight, usually between 11 pm and 7 am. This is the best time to do your washing as you'll save money.
Wash clothes on the shortest cycle (often referred to as "quick wash") that's practical for your needs. This means less water, heated to a lower temperature and a shorter spin cycle to save water and energy. Bonus - this cycle causes less damage to your clothes over time so helps them last longer.
Given that energy prices are at their lowest between 10pm and 5am, I would advise scheduling your washing machine to run into the early hours of the morning. Doing this can help you to significantly cut down energy costs."
What is the cheapest time to use your washing machine? According to the Daily Record, the most expensive time to use your washing machine or tumble dryer is between 4pm and 7pm. Energy prices are at their lowest between 10pm and 5am, but make sure you never leave it on over night as this could be a fire risk.
You can quickly wash a few clothes without using a lot of energy, in fact, a quick wash can save up to 60% of energy* compared to a regular cotton cycle, and that's not all.
But the eco mode is almost always worth using. With your washing machine, make sure you lower the temperature. Switching to a lower-temperature wash yields an energy saving of 35-59% according to a report from the University of Surrey. Pressing the eco button on a hot wash doesn't do much at all.
Whether it's your washing machine or dishwasher, some energy suppliers offer cheaper tariffs if you run your appliances during off peak times, when fewer people are demanding energy supplies. While peak hours will vary slightly by area, it's a great way to save money and keep those bills down.
It's cheaper at night, when demand for power is at its lowest. This quieter period is called the off-peak hours, which usually falls between 10pm and 8am. Conversely, peak hours are during the daytime, when more people are using electricity and demand is higher.
Electricity prices are higher during peak demand hours and lower during off-peak hours. Peak times may vary by rate and/or energy provider but are generally defined as the hours between 4 to 9PM.
By using less energy, a quick was will also save you money, too. But, a quick wash isn't the best option if you need to wash stained clothes. The temperature is too low to lift a stain properly, so always use a full wash for this.
It depends. If you're not washing heavily-soiled clothes or dishes, you can probably expect a decent result from using your washing machine or dishwasher on eco mode – the worst that can happen is that you might need to wash them again. But it's worth a shot for the water and energy savings you could make.
Wash at 30°.
This is adequate in most cases and is gentler on your clothes! If you are washing at a lower temperature, choose a liquid detergent. These are more effective because they are already dissolved. Give preference to longer but more economical eco programmes (30 to 45% energy saving).
How much energy am I actually saving? In Eco mode, a wash cycle uses 0.73 kWh*. Compared to the Auto programme, that will save you around 523 kWh over a year. That's enough to power an energy-saving lamp for about 28 months.
30°C washes softer fabrics better than 40°C, which is why 40° is better for your everyday clothing, and fabrics that are harder e.g. wool. This is the temperature that most consumer testing boards use to measure the performance of the machine. materials at 40°C and the results will be just as good.
Generally speaking, cold wash cycles are best for delicates, colored, and normally soiled clothing; warm water is best for more soiled clothing and whites; and hot water is best for very soiled clothing or for loads, like underwear and towels, where you want to remove germs and allergens.
Electricity still runs inside an appliance even if it's switched off. If electricity is present, there is always the possibility of something overheating or shorting out. However, it is far more likely that if something was to go wrong it would be whilst the appliance is in use.
The most expensive time to wash your clothes is between 4pm and 7pm. You could save cash if you're on an Economy 7 or off-peak tariff by putting your load on during less busy times of the day. Martin Lewis said, for those on eco tariffs, the cheapest rates are usually available between 11pm and 8am.
Prices are higher during times of day when demand for electricity is generally higher and the cost is greater, called peak times. Monday through Friday 4 to 9 p.m. are the only hours that are higher-priced (peak). All other times are lower-priced (off-peak).
There is no definitive answer to this question. Washing your clothes by hand will use considerably less water than using a machine but unless you use cold water, the energy required to heat the water in your home probably outweighs the electricity usage by your appliance.
Given that energy prices are at their lowest between 10pm and 5am, I would advise scheduling your washing machine to run into the early hours of the morning. Doing this can help you to significantly cut down energy costs."
