lazyarcher - are you 100% sure that the propane catalytic heaters are approved for use in enclosed spaces? I would love to have one but I read the outside of the box thoroughly and could not find anything that indicated that it is safe for enclosed spaces. I'm especially cautious of this because my hunting buddy lost his brother several years ago to carbon monoxide poisoning in a hunting shack. His heater was a flameless catalytic white gas heater and it killed him. They always say that the CO is tasteless and odorless so you can never smell it. And the effects of CO are acumulated in the blood stream over a period of time and are not reversable. I guess that means that we could do just fine for the first night, hunt the next day, and then during the next day at dinner time pass out from acumulated effect of the CO. Kind of scary stuff.
