If the inside is the same as a 55UL, yes Ive had some. My Dad has one. His chimney doesnt have enough draft for ant full time but did burn some in really cold windy weather. I thought it was very very efficient with the thingy?? closed above the fire. My Dad absolutely loves the stove and uses it mainly with wood, which it burns really nice as well. If you let it idle away real low, it will hardly use any fuel but still put out a lot of heat. It will give you good burn times, dont worry about that. I think its a little less then 100 pounds but could be wrong. I think you will be very happy with it.
If you ever burn wood in it, cover one grate with firebrick or let it ash up. It burns slower that way and leaves coals for reloading.
