How much can I *with margin* load a floor with joists of 175x45, cc60, pine floor 28 mm? Looking at a stove that weighs 255 kg with a load area of 635x485 mm. Of course, I would put a sheet under the stove. Would it work? Spontaneously, it feels doubtful even though I don't have a clue calculation-wise...
 
If you have a three-seater sofa where three people each weighing 100kg sit (not unreasonable). Distribute this on 4 legs each measuring 3*3 cm... I also have no idea about calculations but in relation to each other, it shouldn't be a problem. Others who know better about this surely have a better understanding

Thank you, yes the reasoning sounds reasonable.

Just talked to the neighbor who helped me with the new joist and his response was "255 kg? Are you kidding? That floor can support up to a ton." I don't trust that, but 255 kg feels quite safe anyway. Does anyone know if the floor plate distributes the pressure at all or if it doesn't have any practical significance (quite thin brass sheet)?
 
Actually, I think your neighbor isn't entirely wrong. I have a friend who has a 700l aquarium on the second floor. Not a hint of sag...

The sheet does not distribute weight over its entire surface, only very locally around the feet/base of the stove.

I also believe that the floor can handle this without any problem.

By the way, have you counted the chimney in the weight? If you are going to use a modular chimney and have high ceilings, I assume they can weigh quite a bit?
 
Probably not a problem. But if I were you, I would contact the chimney sweep (who has to approve it). There are some odd rules about load-bearing capacity when it comes to stoves.

Heard about a case in central Stockholm (albeit in a multi-family house, different rules), where they applied for and received planning permission for a tiled stove. When everything was ready, the chimney sweep ordered demolition, because the beam was too weak. His requirement was that there should be a fireproof beam under the stove. If the house burns down, the tiled stove should still stand on the chimney stock. The reason was that if it burns so that the beam collapses, a heavy tiled stove should not fall and break through the beam to the next floor below. But this was not discovered until the stove was in place.

As far as I understand, the chimney sweep's decision cannot be appealed.
 
Okay sounds good. No, there is no problem with the chimney - the stove is located by the old masonry where I currently have a cast iron stove. The only addition is a small bend in the stovepipe.
