Even worse, all that exhaust gas that goes up the chimney has to be replaced. And it's replaced by cold air from the outside coming through all the little books and crannies of your house.

I have seen slow combustion fireplaces still drawing in air from the room in front of them, leading to your exact comment.

Seems like it could be fixed with a simple design change.

But I am not a fireplace lawyer so I won't profess to know.

There are many different designs that have tried to solve the issue. Both from capturing the heat lost up the chimney and supplying combustion air from outside. They all come with downsides and ultimately forced air heating won out.
