Well I know it's cheaper and if we are strictly talking emergencies it might be the way to go. We have a fireplace here so if we have a power outage, I don't use it to heat a large area, but it has kept the room in our hunting tailer..roughly 10 x 8..comfortable when the temperatures dipped into the low 30's.

As far as a case of propane...you can buy an adaptor so you could hook it to a 20 lb tank..although if storage is a problem...you can figure conservatively 6 hours on a 1 lb canister.. so you would need 12 for 72 hours of continuous use..easily stored, but I won't suppose to know how much space you have to deal with. <img src="/images/graemlins/smile.gif" alt="" />
