In Germany they're called kachelofen - Wikipedia page here: https://de.wikipedia.org/wiki/Kachelofen (in German but Google Chrome will translate on the fly)
I know nothing of this company except that they have a nice mix of modern and old-fashioned styles: https://www.kachelofenwelt.de/design/bildergalerie/kachelofen-heizkamin/

A batch box feeding a bell....used as a wall between two rooms has always seemed like it had great potential,
Both to be aesthetically pleasing, and double your exposure of heated surface to two rooms at one burn!
If, (and mind you I'm stretching past my experience here) multiple floors had common wall lines a multistory bell could potentially expose 6 rooms over three floors to one batch box.
If overcooling the smoke was a concern then a narrow wall say four foot broad with a torturous path to ensure contact could still expose each room to heat.......

I dunno if your drawings are to scale but from a cursory look it seems that you have a common wall between the living and the music room that carries through the second floor bedrooms.
If a brick bell was built on the bottom floor with a batch box (preferably in the music room since it has outdoor access) carrying through to say at least 4' above the average floor level on the second floor you would have good exposure to four rooms.
At the least if building a 4' wide bell it would entail removing one stud from the lower wall and half of one stud from the upper wall, and the addition of a steel beam (supported by the bell itself!) to support the upper floor.
Alternatively it could be built against the wall, and the wall covering removed to expose the second room to the bell leaving he studs in place, but that seems like a far from handsome alternative.
The caveats are;
You need a solid foundation clear down into the earth for that much masonry, no stretch of the imagination will allow such tonnage to depend on framing.
$ 8,000 to $ 10,000 USD does not sound unreasonable if no unforeseen circumstances arise. Average heating costs run $1500 to $4000 yearly so the pay off is well within five years.
A sane man intending to occupy the home for generations would pay an engineer to ensure adequacy.
