Stopped in my local Coastal Farm and Ranch yesterday and took a look at some Quadrafire stoves. I was very surprised to see the 5100 insert quoting 14 hr burn times and the 5700 stove right next to it, with the same 3.0 ft^3 firebox quoting 21hr burn times. These stoves looked identical except one is an insert, the other free standing. Neither has a cat, and both sport the "Automatic Combustion Control" technology.
What could possibly explain such a big difference in burn times?
