I realize this isn't really comparing apples to apples, but I'd like some opinions from those of you who have used both. We've always had a wood stove, and they're wonderful, best way to heat in my opinion. However, the outdoor wood boiler has a lot of good features as well. We like the idea of radient floor heat, and using the wood boiler to power it, also the fact that it could heat a greenhouse or a shop as well. I've heard they're very inefficient however. I'd love to hear some feedback comparing them. Thanks!
