Single-family house, approximately 160m², Bauhaus style; first draft according to our wishes

Maybe it's also because our living/dining room is 52sqm and open to the hallway and upper floor.

Yeah, well, if you have a mansion with several open floors, that certainly puts things into perspective. But for me, it was more about the fact that the desire for a fire doesn't arise. When I think of the cold shacks of the past, I would have loved to have a fireplace. But now the place is so cozy, why have a fire? I'd rather look into the aquarium – it's greener. :P

Yes, well, if you have a castle with several open floors, that surely puts things into perspective.

Even if you write it with a wink, I understand something different by a castle.

A fireplace is "luxury," and there are people who gladly spend money on it, accept the dirt, willingly clean the glass, haul wood, etc. And there is no need for negativity here just because some users have a different opinion on the subject.
This has become increasingly noticeable here lately; I remember how an architect user was badmouthed here even though he was still in the initial planning stage.

I also look into the aquarium, and I curse that thing because it causes me more work and dirt than my fireplace.

Dude, the original poster explicitly asked for my opinion - not yours.

I have now stoked it for the 3rd time. It is 24.2 degrees on the ground floor.

I really like the new draft

Very beautiful fireplace.
What is its nominal output?

Well, a fireplace. More like a little stove. But that only makes sense, it probably won't have more than 6-7kW usefully.
