When I posed a question about switching your iron on and off whilst pressing, you answered in your droves. Thank you all! I never knew irons existed that switched themselves off automatically.
There was one particularly interesting response from Stitch and Witter. (Have you SEEN her cord Beignet? I’m so going to make a version.) Stitch and Witter works for a company that monitors energy wastage. She offered to ask her boffin colleagues which was better: to leave the iron on for an hour, or keep switching it on and off.
Yesterday, she came back with a response. The Boffins had spoken! I know we’ll all find this really interesting, so here’s what they said in full:
I have a response from our boffins! Here’s my question and their answer:
Q: As a seamstress I have to use the iron a lot when making clothes (you have to press every time you sew a seam). I’m not sure if it’s better to keep the iron on for (typically) an hour or whether it would be more energy saving to turn it off in between. But say for example over the course of the hour I have to turn it on and wait for it to heat up maybe six or seven times… is it better just to leave it on for the whole hour?
A: Interesting question! The way to find out the answer for sure would be to find out how long it takes to warm up from cold, and then how long it takes to warm up when it’s already fairly hot (you can tell by listening to it click on and off).Our estimate, based on the data we’ve seen, is that turning it on only when needed is probably slightly more efficient, but it probably won’t make a huge amount of difference. Running a typical iron for an hour costs about 7p, so the amount you’d save by turning it off for some of that time is probably only about 1p. So if it makes life easier to just leave it on, it’s probably reasonable to do that, and look for other ways to save more significant amounts of energy!
Hope that helps everyone! Joanne x
Woah! I love it. The boffins are giving us permission to stop feeling guilty about ourselves. We can do what the heck we like.
Thanks so much for finding out, Stitch and Witter!
