i don't heat my house, but the furnace is natural gas, our house is really cold all the time though so I suppliment that with several computers running distributed.net
i think whoreable's av kicks ass, i don't know why. i just chuckle whenever i see it.
I prefer cold, to be honest. When my dad's gone for a long time I will open all the windows in the house (except those without a screen in them) and maybe take a fan and put in one of them to bring a bunch of cold air in.
(Yes, I'd be a horrible roommate unless your interests are 50% overclocks and subzero temperature watercooling )
we have night-storage here [block heaters] which are sodding useless so we don't use them. sadly we also have a massive victorian bay with sash windows, all with original glass and frames that have dropped over time.
when it's 0 outside it's not a lot over 3 in here and the wife and resort to heat through shivering
