There are also Swedish stoves that really look stylish. We only wanted a fireplace for the eye and the feeling of warmth - not for energy reasons. At the time, we received an offer of 13k+ built-in fireplace, but that was too expensive for us. In the end, we managed to get a Swedish stove bargain for under 1000€ and the thing is really wonderful. As with almost all cheap fireplaces, you have to be careful not to put on too much wood, so that you don’t get steamed in the living room even at the lowest air supply setting, but you still have to put on enough so that the wood burns properly and cleanly. You get a feel for it after lighting a few times, but at the beginning it’s a bit tricky. In my opinion, for the eye and the nice fireplace feeling in winter, these things are no less suitable than a 10k+ built-in fireplace if you know how much wood to put on.
