countess I can assure you my wedding cost a shit load and I can only get 1 proper meal out of a chicken but I do genuinely keep our temp to 15 when we turn it on, think we've got at least another few weeks yet.
We lived without central heating through some of the worst winters we've ever had (snow up to our knees) so it seems luxurious to us.
My mother despairs, telling me this wasn't how I was raised! Hers is currently on at 30.
