Get a big old hunk of flagstone for the base of it. My friend had a little stove like that for his workshop. It might heat a 15'x15' space at best in winter. If you're not going to use it very much, I'd say just get wood chunks for it (like 12" long) and have a nice pile of them next to it handy to burn. Learning how to burn coal in that could take a while and by the time you learned the power would be back on. LOL But if you do want to use it in emergencies, play around with it in non-emergencies, especially with coal, as you will see with the many threads started by clueless coalburners like myself!
