That's very different from benefit. Also I don't see how that's related to what your original comment was arguing for (cost of replacing stoves).
Maybe I should add that I do agree with your conclusion (that replacing the stoves makes sense). I just disagree with the argument from "basic thermodynamics" which gives you "100% confidence".
