The biggest source of trouble with wood stoves in houses are old chimneys 
catching fire or poor installation decisions causing trouble (ie- flammable 
floors and walls to close.  IF your chimney passes an inspection after 
cleaning finding a good quality wood stove becomes a matter of a few simple 
decisions.   Catylist or no?  A catylist wood stove should burn cleaner and 
more efficiently, and I think they are supposed to keep the chimney 
cleaner.  You may also want to make some provision to vent combustion air 
near the stove in order not to create negative pressure in the whole house 
with the stove's demand for air.  If your chimney is junk you may be able 
to drop a tipple walled stainless steal flue down the existing pipe.  You 
may also find your home owners insurance demands this or at least gives you 
a better deal with one.  The out door furnaces are a matter of continuing 
controversy.  Personally I like them, keeps all the fumes, bugs etc out if 
the house, lets you heat multiple building with one furnace, can't burn 
down the house.  There definitely is some loss of heat in the run of pipe 
from the furnace to the buildings, might be better if there was sufficient 
insulation of the pipes.  Also might place a greenhouse etc. over the pipes 
run to try and capture that waste.  Given that you have so much fire wood 
and a relatively short heating season (compared to WI anyway) I think I'd 
give that serious thought.  remember to factor in your insurance savings on 
the outdoor furnace.
