Irons are a common household appliance used to remove wrinkles from clothes. They work by converting electric energy to heat, with the heating element reaching temperatures of 130–270°C. Irons are available in a range of wattages, from 500 to 3000 watts, and the higher the wattage, the more electricity the iron consumes. The amount of electricity consumed also depends on how long the iron is used for and the temperature setting. Steam irons, for example, consume more electricity than dry irons because electricity is used to convert water to steam.

What You'll Learn
Wattage and electricity tariff
The wattage of an electric iron typically ranges between 500 and 2000 watts, with an average iron using 1100 watts when heated on high. Irons with a steam function tend to consume more electricity than dry irons. The wattage of an iron essentially indicates the rate at which it consumes electricity.
The electricity tariff is the cost per unit (kWh) of electricity charged by your provider. This can be determined by reviewing your previous month's electricity bill. Divide the total monthly electricity consumption by the total bill amount to estimate the tariff per unit of electricity. For example, if you live in Mumbai, India, the electricity tariff is Rs 12/kWh.
To calculate the power consumption of your iron, you can multiply the wattage by the number of hours of usage and the electricity tariff. Online calculators or a Kill-A-Watt meter can help determine the exact power consumption.
Let's assume you have a 2000-watt iron and you use it for 15 minutes every day for a month.
Daily power consumption = 2000 watts x 0.25 hours = 0.5 kWh
Monthly power consumption = 2000 watts x 7.5 hours = 15 kWh
Now, multiply the monthly power consumption by your electricity tariff to find the cost.
It's important to note that the actual power consumption can be 10-40% lower, depending on the operating settings and usage habits. Using appropriate thermostat settings, avoiding ironing damp clothes, and turning off the iron a few clothes before you're finished are ways to reduce power consumption.

Temperature settings
The electricity usage of an iron depends on its thermostat settings and the temperature of the clothes being ironed. The higher the temperature, the more power the iron will consume. Therefore, it is important to use the appropriate temperature setting for the fabric you are ironing. If you are ironing delicate fabrics, you may not need to use a high-temperature setting, which can save energy.
Electric clothes irons typically range in power from 500 watts to 2000 watts, with some irons consuming up to 3000 watts. The wattage of an iron indicates the rate at which it consumes electricity. Irons with a higher wattage will generally consume more electricity.
To minimize power consumption, choose an iron with a lower wattage. Many modern irons have an automatic temperature cutoff feature that saves energy and enhances safety. Some irons also have an eco-mode that automatically adjusts the temperature to save energy. Using this mode can help reduce power consumption. Additionally, look for irons with an adjustable temperature feature, which allows you to select the right temperature for different fabrics, reducing the need for multiple ironing sessions and saving electricity.
Steam irons consume more electricity compared to non-steam irons. This is because electricity is used to convert water to steam, which requires additional power. If you use a steam iron, consider the volume of water in the iron, as this will impact electricity consumption.

Steam irons vs. dry irons
The amount of electricity consumed by an iron depends on the type of iron and how often it is used. Steam irons and dry irons differ in several ways, including their power consumption, features, ease of use, cost, and effectiveness in removing wrinkles.
Steam irons have a water tank that produces steam to soften fabrics, making it easier to remove stubborn stains and wrinkles. They often come with special features such as temperature control and steam settings. However, they may be more expensive to purchase and use more electricity due to the power required for steam generation. The water tank also needs to be refilled, and there is a risk of water stains on clothes if not used properly.
On the other hand, dry irons use less power and are generally faster as they do not require time for water heating or steam generation. They are usually cheaper to buy and can last longer. However, they may require more effort to remove persistent wrinkles compared to steam irons.
Some people prefer steam irons for their ability to smooth out wrinkles effectively and for the additional features they offer. Others prefer dry irons for their simplicity, lower power consumption, and faster heating. The choice between a steam iron and a dry iron depends on factors such as the type of fabric being ironed, the desired features, and the user's budget.
To reduce electricity consumption, regardless of the iron type, it is advisable to hang clothes properly or fold them right after they come out of the dryer to minimise the need for ironing.

Energy efficiency rating
The power consumption of an iron depends on multiple factors, including its power rating, operational hours, energy efficiency rating, and standing loss factor. The formula for calculating an iron's power consumption is: Total Power Consumption = Power Rating of Iron x Total Operating Hours. For example, an electric iron with a wattage rating of 1000 watts, used for 1 hour daily, will consume approximately 1 kWh of electricity per day or 30 kWh per month.
The electricity usage of an iron is influenced by its thermostat settings and the temperature of the clothes being ironed. A test conducted with a non-steam iron set to a moderate temperature suitable for ironing adequately dry clothes found that the electric heating component was active only 30% of the time. This means that despite a high wattage rating, if used properly, an iron may not consume a lot of electricity.
To use an iron efficiently and effectively, consider choosing an iron with an automatic temperature cutoff, a safety feature common in modern irons that also saves energy. Opt for models with energy-saving controls that switch off the iron if it is not used for 10-15 minutes. Additionally, minimise ironing requirements by reducing the spinning cycle if using a washing machine and drying clothes on hangers, as they tend to leave clothes less crumpled. Use an appropriate thermostat setting while ironing, as extremely high temperatures can damage clothes and increase electricity bills. Avoid ironing wet clothes or dampening them before ironing, and turn off the iron when only a few clothes remain.
The choice between a steam iron and a dry iron depends on individual requirements and usage patterns. A dry iron is lighter, cheaper, and easier to use, making it a good option for those who do not iron frequently. On the other hand, a steam iron offers more efficient wrinkle removal and the flexibility to use it as a dry iron for certain fabrics, making it a better choice for regular users.

Operational hours
The power consumption of an iron depends on its operational hours, or how long it is used for. Irons are generally used for a small duration of time, with many sources assuming 15 minutes of daily operation.
The formula for calculating power consumption is: Power consumption = Wattage of the appliance x Operational hours. So, the longer an iron is used for, the higher its power consumption. This, in turn, leads to higher electricity bills.
For example, an iron with a wattage of 1000 watts, used for 1 hour daily, will consume approximately 1 kWh of electricity per day, or 30 kWh per month. A 2000-watt iron used for 15 minutes a day will consume 0.5 kWh of electricity daily, 15 kWh per month, or 182.5 kWh per year.
It is worth noting that the actual power consumption of an iron can be 10-40% lower than the calculated value, depending on operating settings. Irons with higher wattages may not consume excessive electricity if used for a short time. For example, an iron rated at 1200 watts, used for one hour, consumed 0.4 units of electricity in an experiment where the heating element was only active 30% of the time.
The power consumption of an iron also depends on other factors, such as its power rating, energy efficiency rating, and standing loss factor. Steam irons may consume more power than dry irons due to the additional steaming requirement.
