This is my little experiment this year. I installed some new air tight doors on my livingroom fireplace more for keeping the cold down drafts out, but still like an occasional fire every now and then. I saw some pellet baskets on the net and figured it might be a good idea for my fireplace. I didn't want to pay the $100 or more they were charging, so I had a local metal fab build me one for $40. It's just a basic basket made out of 13 gauge expanded metal that I sit right on top of the grate. It holds a max of 20 lbs of pellets and from start to ashes is about 6 hrs. It does put out some decent heat out my top fireplace vent.
