Fire Place Inserts: Wood, Pellet, or Gas?

As I mentioned in this post, we had a few pangs of eco-guilt about using our wood fireplace.  Wood not only emits more pollutants into the air than other fuels, it doesn’t even do a good job of keeping our house warm during the cold winter months.  We started looking into a fireplace insert that would allow us to sit by a greener, cleaner fire.

First we looked into a gas fire insert.  We already have a gas line to our house, so we thought this might be the way to go.  Natural gas is the cleanest burning fuel out there.  However, we were not big fans of the fake-looking logs or coals that come with gas fires.
