If you have access to mixed hard and softwood for the wood stove, I think you will find that the wood stove may be the better option. I am very happy with my wood furnace, and if I could have used a wood furnace in my shop I sure nuff would have. However, because it was a commercial business an highly flamable liquids were present (usually sprayed), an open fire was out of the question for insurance coverage. They did allow me to have a propane forced air system which was kind of weird, cause the pilot light was open.. :? :roll: ... Oh well.. that is life.
I do have an older Enterprise that was in the old house that was on the property when we bought it. It is stil over at my father-in-laws place. I am thinking on putting that in the pole barn to help heat.. should be economical as well as warm once it is insualted.
I do like the Tenons for the rails and stiles.. nice work :!:
