From what i gather, op has to carry stuff to his area. Probably snowed in.Is where wind you can harness? Running water? Pellet stoves work better then wood for generating heat. And you can fill the bin and go all night without needing to add any more fuel.
I have a rpg rocket stove (from, "shtf and go") with a "griddle me that" stainless cooktop thingy, it uses 4 inch stovepipe. That has a pellet hopper option. The thing gets scary hot! It really requires some kind of heat capture device to be cheap on wood or pellets. But for fast super boiling it's pretty good. I mainly use mine to quick boil or cook, multi gallons of water... As i said. It's scary hot. Apx 900+f at the burner area.
If i was to use it inside, I'd want stainless pipes. Luckily they exi$t... However it's kind of a hassle to use with pallets without the large hopper add on. With regular wood it's easy to use. But it doesn't hold much.
The manufacturer says he heats a large area with one using a metal 55 gallon drum with piping inside and filled with sand. It's really heavy.
