Well...that's sort of true. But sort of not. I work for a company
which makes one helluva lot of burners--we make wood, gas, and pellet
stoves and fireplaces.

I promise you that it wouldn't be too hard to design a 30,000 BTU
grill that uses 2 or 3 times as much fuel as, say, a Weber 30,000 BTU
unit. Bad design's easy to do. :\

So, what you said is true if we assume (and that's not necessarily a
good thing to do) that the burners are equally efficient--which of
course is dependent upon their being designed, and made, well.

Uh, we can't change the laws of physics. It takes a given amount of fuel to
make 30,000 Btu of heat. Not every grill will utilize that 30,000 Btu the
same way, but every single one of them will use the same amount of fuel to
generate it. I didn't write the laws of physics, but we all have to abide
by them. Propane has 91,044 Btu per liquid gallon no matter how good or bad
the burner is.
