I have used the jet type job heaters, big draw back is that they are very loud, kerosene really stinks, propane isn't that smelly but will get to you after 8 hours. Barrel stoves are cheap to set up and use if you have a good wood supply but on windy days you can get smoke fumes coming in. I have used one of those infrared overhead heaters but they must be used in a well insulated room to work good.
