Hope you're doing it the Scandinavian way, and installing a log burner as well.
As if you aren't, you'll have to give your air con unit a day or twos notice when it gets cold.
The Scandinavian way is to eat rotting fish so no, I won't be installing anything that burns things. I don't give my fridge notice when I buy ice cream, and I won't be giving my heating notice of cold weather. Mind you, I won't be giving my car notice of fuel price increases, since it runs off cheap electricity now.
You pay to fill your car up?
Peasant.
Anyway, it's a bit chilly to going to chuck another log on.
Ah. Lovely.
