revised Is placing a heater in the coldest part of a room the most efficient place to put it?
nope .. "best" is less specific, and I noted two notions of "best" in the question. (uniformity and cost)

comment How much heat from a fire actually warms your home?
@ Steeven @ Floris @tpg2114 @ WetSavannaAnimal I guess another issue that would change the radiation /vs/ warm gas tradeoff, is something like a roaring fire must radiate more, whereas smoldering embers could transmit slower heat more efficiently?

@Floris Sorry to make it complicated!

@Steeven Or maybe there's a way to slow down the smoke / heated air leaving the chimney, thus "lengthening" the chimney without actually lengthening it. Or like pipes that snake through a house are "tall" (long) but don't require the house to be tall.

@Steeven Well, maybe the "house" is actually a "factory" or "school building" or …

@Steeven Ah, nice to know. So would a very tall chimney capture more of the convection products? Or maybe a tall one with thermally conductive "bricks"?

@Steeven If the plate model is valid, I would be saying: fire ⊂ chimney air ⊂ bricks ⊂ house, as like encased sets. But with an opening/connection between chimney air ↔ house.

@Steeven I'm thinking of "heating the house" as heating the air in the house. So the bricks store some of the heat from the flames but I'm only considering "the house" to be heated by the bricks when they give off that heat to the ambient air (outside the chimney).

comment Is there any place for teleology in physics?
I like the fork example at the top of Wikipedia. We could also talk about teleology in evolved body parts, in some sense. (Wings had an intermediate "purpose" which was not flying.) But here's the important issue for me: Can you design crucial experiments proving one view or another about teleology correct? If you can design such an experiment whose conclusion convinces basically all comers, then the teleology debate could be like ideal science.
