After my research into how much tumble dryers cost to run - I wondered how much it costs to use an iron. Unfortunately it only costs 10p per hour. So in my house that's less than 40p a month.
It has always seemed a strange thing to me. Flattening clothes. I was really hoping it was going to be expensive and un-environmentally friendly so that I could give it up and tell everyone I'm doing it to save the planet. Sad times.
It still uses electricity which takes resources to produce so only have the iron switched on while you are using it. Only iron what is necessary and be mindful of the electricity you are consuming...
