From a related yet different perspective, do I introduce any trouble by burningmy wood burning fireplace insert?://www.mail-archive.com/biofuel@sustainablelists.org/ Your insert with a fan is probably 300% more efficient than a fireplace. That means instead of 98% of the heating value of the

I know its not much better but, I believe our insert is rated at 40% efficiency. We plan to move to a more efficient catalytic wood burning insert as soon as we can swing the finances. Vermont Castings claims 78% efficiency of one of their models. Kirk wrote: Your insert with a fan is
