The company's brochure says it can run up to 24 hours, but is it really true?
It's a little like gas mileage claims.
When something says "...up to..." that means that, yes,
you "CAN" get that. But you probably won't...
For the most part, unless you are WAY off, there is X amount of heat
per pound of coal. So it depends, like others will tell you, on how much
heat you need to stay warm.
I have a Mark III.... I can make it go 24 hours.
As long as I'm not interested in staying warm.
If, when it's 3° and the wind is howling at 20mph, I'm putting coal
in that baby every 10-12 hours. With the side of my stove at ~575°-600°.
But. What I prefer doing, is putting smaller amounts of coal on,
maybe every 6 hours, just to avoid any big drop in temperature,
due to covering a smaller fire, with a large amount of coal.
