Hmmmmmm so our flat has this weird temperature differential, its never above about 15 degrees downstairs compaired to either upstairs or the outside world. Which leads me nicely into even if its about 25 and humid as a bastard outside as I have just found out I mean how can it be that different, we dont have double glazing, AC or any other temperature altering device. We have some freak heat sink of a living room, hmmm I'm thinking House or the school in Buffy, take your pick.
