Does it not go through the chimney? Have llivewd in flats all my life.
Depends where the burner is. Folks have them in rear extensions which means they can't use the chimney, and they put a twin wall flue out through the wall instead. Ugly as fuck, but when you are using it, you don't have to look at it. Neighbours not so lucky.
Cam imagine a lot of folks take one look at how fucking ugly a radon sump flue is, look at the percentage chances, the cost and faff, and sack the thing off.
