Just curious what everyone's DIY shacks are heated by. Most commercial shacks use vented camper style furnaces. But the DIY ones I see are mainly Blueflame or buddy heater styles. I know what I prefer but I want to hear from everyone else, like an interactive poll. I also find it interesting that geographical area also tends to change preferences, my current location is dominated by propane heat, Near my in-laws, its dominated by wood stoves.
What do you have an why?
