Getting my morning dose of CO. Yum! Testing out the heater before I put it away, hopefully never to be needed. It gives off a lot of heat! It made the room jump two degrees in just a few minutes. Nappy Knolls isn’t that big. One cylinder lasts about five hours, and I got six to keep with my gear. I also have a cute one burner butane stove with cylinders – the kind that’s in a little metal suitcase – so I can heat up soup in an emergency also. Or even make a grilled cheese! Cut to me being a prepper.
