Had it up from 16 to 20 for a couple of hours twice in the last wee/10 days or so. Just when it was (or I was) feeling chilly even with a fleece hoodie on!. I almost put the electric blanket back on the bed but I have a new mattress and even with a light duver (4.5 Tog) I’m still too hot and wake up during the night!. Last cold spell I had my 13.5 Tog duvet on, tried it last week and had to take it off again!, too heavy and too warm!.
I’ve read electric blanket is very cheap to run 2p an hour ?
