I want to second an electric blanket! I’m in the US, so our numbers might be different, but the comparisons should be equivalent.

I have an electric space heater and an electric blanket. The heater uses 1500W, and the electric heater uses only 100W. So while the space heater will warm up the whole room, if I’m watching TV, I might prefer the electric blanket – it’s much cozier. And it costs 1/15 as much to use!

It’s tougher at Publix. They have that southern passive-aggressive niceness in their DNA
