Northern N.Y.,we get real winters here.I cut and burned wood for myself and my parents,30 cords per year on our property.Wood itself was free ,the rest not!
I replaced my wood stove with a Vermont Casting propane unit(38K) ,primary is forced air oil.That was 25 years ago and don't regret at all.Plus with the propane stove,it works if we loose power.
My son as an out-door boiler,again wood is free outside of labor,gas,tractor ect.He burns at least 30 cords per year.
There are more efficient units but they require dry wood and cost 2k more.
If you have neighbors smoke may be a problem.
One of my sisters tried a pellet stove;big mistake;they switched to a propane boiler.
As you get older;wood looks a lot less appealing.
Put your money into insulation I.M.H.O.
