ᐅ What should you consider when buying a tunnel or see-through fireplace?

We plan to use a tunnel/see-through fireplace as a room divider between the dining room and the living room.
The passage on the right side is 2m (6 ft 7 in) wide, and on the left side, the opening for the stove is 1.30m (4 ft 3 in). Wall thickness is 40cm (16 inches).
Attached are a current photo of the wall opening and an image (from Pinterest) showing how it should look eventually.

What should be considered when buying a stove?
How much does something like this typically cost?
Which stove manufacturers are recommended?
Can the stove and its surround be installed by oneself, or is a professional stove fitter required?

Thank you very much

No idea. But that wasn’t a load-bearing wall you demolished, was it?

I can only give you the cost, approximately 12,000 to 18,000 euros. Depending on the specification.

That’s true. That was my first thought as well. First build the wall up, then knock it down. Makes perfect sense. You probably did it yourselves, didn’t you?

"Build up and then knock out"—from two rooms before, to one room after. This approach is sometimes used during renovations...
No, it was not a load-bearing wall, and yes, everything was checked in advance with a construction company and a structural engineer. However, this is not relevant to the topic now.

Pay attention to the correct sizing of the stove – if the heating capacity matches the room size, everything works well. If not, the stove will soon be left unused.
