I have a medium sized insert and I'm always experimenting with my wood ratios, I have been burning mostly Norway Maple with a lot of other stuff, I have A cord of red oak, black locust and beech, well tonite I loaded with only beech after having the insert run all day, I must say, this is the hottest I have gotten my room, does anyone else use beech on a regular bases or occasionally? Thanks for any and all input....
