Outdoor wood boilers are somewhat popular (don't help much without power though), but I'd hazard a guess that more homes than not just have a small backup generator rather than rely on any kind of wood heat. Might be different elsewhere; propane is cheaper than the national average where I live, so my experience might be skewed.
