Fit well in an urban-semi fireplace I would think?
Have to say I agree with Darren - fit it yourself it's not tricky. Some of the quotes we had for fitting a stove were just a joke!
For what it's worth based on previous experience we're expecting to burn about 15 tons of seasoned wood this year - giving all our heating and hot water. That's for a smallish 3 bedroomed old cottage made of mud and stone (impossible to insulate well). We keep it warmer than most would choose to at the moment though as we've got two young children.
BTW everyone I know with a Jotul thinks they're great
