but requires a plumbed in central heating system which we don't have.
Air to Air split systems are a thing and would be efficient most of the time in Scotland. There's probably several days per year when it's below 5ish degrees and damp air which will bring the COP down closer to 1
I like heat pumps, but we had below freezing for a month, now thinking, UFH ground floor and panel heaters upstairs but just need to make sure it is at least cost neutral and still warms the house properly.
