I 110% agree, re: "fireplace novelty." Worthless, as in the heat goes up the chimney, mostly.
However, as one that has a wood burner, I disagree with the/your notion, "that in order go heat a house full time you need exponentially more wood." So what? A $25 permit allows all the wood we need...plus great excercise (cutting, loading, splitting, stacking).
We have to open windows, no matter how cold it is (sub zero - regularly) once a wood burner is cooking.
The radiant heat that eminates from a wood burner fire (about 30 minutes in), is unreal - heats our house rapidly.
Disadvantage. If one is in need of a steady "68-whatever," wood burners ain't gonna suffice.
Plus, the futzing around with a wood burner...kinda tedious. Then again, me and my gal? Less time in front of our monitors!
