Colorado, I've found a 20# tank will last about 30 days of hunting in one of our box blinds....based on our average use. I can't really put that in hours but I don't think its excessive. I fill the tanks once a year and there is always some left in them. Our blinds are 5-1/2'X6' and not insulated. Plexiglass windows. Some of my oldest stoves are nearing 20 yrs old now. They have a burner in them similar to a coleman stove and burn very quietly.
We eat organic in our house, we just have to shoot and gut it first.....
