I use this wood burning stove in a 7M Bell tent

a 7M bell tent is 23 feet round (415 square feet) I have had the tent and Grizzly in temps -10 degrees in Co elk hunt, to the 80 degrees of offroad riding in Glamis camping in the sand. High winds, lots of snow, and hot days but COLD nights. I love this stove and once you learn how to use it, (that goes for all wood stoves) you will love it.
