After years of using small woodstoves to heat 2 permanent box blinds at a friends property, I'm looking to invest in a Buddy heater. Life has gotten busy and we no longer have the time to spend multiple weekends in the woods between crops off and the start of the season to prep firewood so we can have heat. I realize it is a 1st World problem, but when we are in the blinds, it's more about friends, cooking, and community than hunting. I prefer the wood heat but it requires work and I'm not so sure that our activity in the woods before firearm opener has reduced our luck in past years. So I'm looking at the Mr. Heater Buddy line of heaters and looking for suggestions on what size would be best. The box blind I typically use is 8x8' and uninsulated. Since it is portable, I have other uses in mind: - 2 man pop-up hunting blind - 3-4 man pop-up ice shanty - 8x8 or 6x8 box blind I hope to build on the back of my property I would plan to use a 20# tank and adapter hose. I would just leave the tank at the blind and transport the heater and hose. Is it best to go with the Big Buddy or is the regular Buddy adequate? Thanks!
