ᐅ Issue with Chimney Sizing – Panorama Fireplace as a Room Divider

Good evening everyone,

We have planned a panoramic fireplace as a room divider in our living area.

The living area is about 60sqm (646 sq ft) with a volume of 150m3 (5,295 cu ft).

There are some nice fireplaces from well-known manufacturers that we find visually appealing, but in our opinion, all good fireplaces have a rated output between 9kW and 12kW.

According to online research, this is probably a bit too much... however...

Are there any experiences from people who have already had to make such a decision?

What happens if you simply use less wood...
(I know it is said that the glass then gets dirty more quickly – any experiences?)

Thanks in advance!
