Just that really. We've got a 1970's gas fire which chucks out amazing amounts of heat and I'll be sorry to see it go but I think it's time for something a bit more modern as I can't see it becoming fashionably retro any time soon... 
I love being warm but the fire is in a small room - bog standard 1930's semi detached, so it doesn't need to heat a massive space.
Ideally I'd have liked a wood burning stove fire but dp has said no that's been ruled out....
Any idea what kw I should be looking for - would be very sad if we got a new fire and it was crap.
