I have a natures comfort wood burner. Works awsome. I wish it was more efficient, but, it is what it is. The gasifiers, are just too costly. I would say, if you have a free supply of wood, its worth it. I'm lucky, all my neighbors have a lot of acres of woods. I can have all I can cut. and all within 2 miles of my house. Last month, Rick, my neighbor, said he was cutting out a drainage ditch between fields. about 200 trees were coming down. He is cutting them and dragging them up to a lot by the road. All I have to do is take my trailer up there, cut up logs, throw on trailer and take home. My friends laugh at me, But as long as its free, Im taking all I can get. For those that say its too much work, I like it. I like getting outside and cutting wood. Its good exercise for me.
I might be satisfied when I have 5-6 yrs worth...LOL.....
