My house came with a pellet stove. It's nice when it's working, puts out lots of heat, runs for several days without refilling and it has an option to run on a 12V battery at reduced output. But it's finicky to keep running, I have to be really diligent about cleaning. The ignitor went out a couple times. There are safety interlock microswitches that get dirty and don't work.
The pellet market is weird here too. You basically have to wait for Home Depot to restock them in late August, them buy a year's worth before they sell out. It's a niche product that is bulky and the bags are easy to damage, not many businesses sell it.
