It's day and night compared to that same house back when it had a regular open fireplace: smoke would drift inside the house, no matter how cautious I'd be. And the efficiency was terribly bad.
Now I still get to enjoy the view and once the fire is well started and the smoke correctly goes through the chimney, I can even open the enclosed fireplace's for a while and hear the crackling / get the full ambiance.
Lovely. I hope to go there in december. Falling asleep in front of the fireplace is one of my greatest joy in life.
It did cost about 5 K EUR IIRC (to transform the open fireplace into an enclosed one) but then warming the house with wood is super cheap (an enclosed fireplace is much more energy efficient than an open fireplace).
FWIW I warmed the house during the entire summer with five "stères de bois" [1] (an old french unit that isn't used for anything anymore beside wood logs meant to be used as fuel), paid 60 EUR each. So 300 EUR to warm the house (south east of France, mild winter).
BTW: house in the middle of nowhere, hardly any neighbors. So they don't get my smoke and I don't get their.
