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!.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
