Power consumption & energy usage of electric iron

An electric iron or a steam iron or an iron box is a tool used to press the wrinkles out of your clothes so that when you dress up you look smart and neat. It is a basic tool that converts electric energy to heat. It consumes more electric power than most of the other appliances you have at home. This energy usage calculator for electric iron can help you calculate the energy consumed by the iron box and the usage charges.

Electric iron shall not remain ON always. Once the set temperature is reached the power to the heating element is cut off. Electric irons are available in various ratings and features. Electric irons consume roughly 350 watts to 3000 watts of power, varying from one model to another.

Enter the wattage, hours of usage, and cost per kWh. This electricity usage calculator for electric iron gives you the total energy consumed by an electric Iron and utility charges.

The electricity usage depends on the wattage, number of hours of usage. The utility company charges you for total number of kilo-watt-hour of energy you have consumed. Kilowatt hour is the product of power consumption of the load and the number of hours of usage.

Working of electric iron

An American mathematician Henry W. Seeley invented the electric iron, in 1882.

A temperature of 130 degree Celsius to 270 degree Celsius is needed to remove wrinkles from the fabrics. To attain this temperature, an electric iron makes use of heating element called Nichrome (80% nickel, 20% chromium). When electric current flows through the heating element, it is heated up. This heat is transferred to the base plate of the electric iron.

An electric iron consists of a temperature regulator and bi-metallic strip to limit the temperature of the base plate. When the desired temperature is reached, the bi-metallic strip cuts of the current flow to the heating element. Hence, it prevents overheating.
