I've lived in cold homes and I've lived in hot homes, personally I much prefer cold homes - heating in this country is pretty good, cooling not so good. I guess the great summers of 2003 and 2005 were just so unpleasant I am scarred by the memories of them.
You have AC in the UK? Did you install it yourself or was it pre-installed by the builder?
Yep, AC in the UK (bizarre I know). We didn't install, the developer put into every flat. Rarely gets hot enough to use, I recall about 10 occasions we've used it. Costs a bit in maintenance as well to boot.
