IPE or HEA for a 6 x 6 meter room

[Leet]

Hello.

I want to remove a wall and replace it with a load-bearing beam. The length of the beam will be about 6 meters, and the entire width of the "new" room is 6 meters (the beam is in the middle of the room, so it's 3 meters per side). The house is a 1½ story villa, and the existing joist is 220x45. Will IPE 220 be sufficient, or what do you think I should use for the beam?

Thanks in advance

Moved from technology. I believe more "dimensionerings freaks" read in this subject.

A relevant question is what it looks like upstairs; is there any load-bearing wall that helps the roof trusses?

Upstairs, there are no load-bearing walls supporting the roof trusses in the middle over this wall, instead, there is an open room. The roof trusses rest entirely on the outer walls and maybe a little on the middle wall in the house (The wall I want to replace with a beam). The main purpose of the wall is to support the floor structure between the levels.

On the upper floor there are no load-bearing walls supporting the roof trusses in the middle over this wall, instead there is an open room. The roof trusses rest entirely on the outer walls and maybe a little on the central wall in the house (The wall that I want to replace with a beam). The main purpose of the wall is to support the floor joists between the floors.

There is no problem calculating if it's just the intermediate floor/upper floor that will load the beam.
But I'm not really clear on your latest post, is there a load-bearing wall upstairs that supports the roof trusses or not?
This is very important to establish first, a "maybe a little" is not sufficient as fact.

Will fix a picture with measurements and everything when I get home tonight so maybe it will be clearer.

I don't dare to have an opinion on the beam dimension. But another thing you should investigate is how to attach the beam. If I interpret it correctly, you have a 36 sqm room above this beam. In homes, you design for 200kg/sqm plus the dead weight (which can almost be disregarded, I think), i.e., 7.2 tons. Half of that load is placed on the beam, i.e., 3.6 tons. It then distributes so that it becomes 1.8 tons per support point.

Often, you have to reinforce the foundation to be able to handle such a point load.
