I wish I could lend some advise to Bit burning that might help
I will say that as with anthracite coal stoves im sure there is a VAST difference between a great burner vs a crappy miserable burner. Im not so sure the model you have does anything great (wood, bit or anthracite)... it appears to be the most basic design from 1800 reproduced as cheaply as possible for decoration more than "real, functional, quality home heating unit. I would not believe that Home Depot and Chinese ebay companies really have a handle on anything coal, other than profit margins and supply ability. I dont say this to offend you (My opinion is based on zero real world experience with bit)... I would just hate to see you base your experience on this one stove. Its sometimes amazing how you can spend pennies on the dollar for a tried N true quality stove VS. buying Junk brand new
maybe someone can offer you some quality Bit burners that may turn up used that you can keep an eye out for??? this may be the best avenue to pursue at this point? One stove that comes to mind is called the "Warm Morning" (massive amounts of preheated secondary air flows to all levels of the firebed via firebrick) and a stove that is very controllable to hold heat and maintain a steady burn OR knock your socks off if needed.
I hope some folks who know bit. stoves well can make some suggestions on models... happy Thanksgiving!
