Impressed how BIO BLOCKS burned in fireplace insert!

Last winter I burned BIO BLOCKS in my fireplace insert for the first time. I was greatly impressed with the product. Not only were they easy to stack in my garage, but they were very easy to start, gave very good heat, and also had a nice flame. It only took 2 of the 12 packs to last for a 24 hour period. I’ll certainly use them again this year!
