The number Codehead posted is correct and is for Bioheatusa in Lyme, NH. I called on Dec 22 and ordered and received the baffles on Dec 23. Really outstanding service. The cost was $255 plus shipping (to Vt that was about $22). I found a bulletin from HS Tarm on the coal baffles somewhere on the net and printed it. I think I have the PDF file on my computer. The prints are not too clear but if you are interested I can post the PDF (or the link if I can find it). The baffles have significantly improved coal burning. However, keeping them in place is a bit challenging. I think the design could have been better. I am also worried about the longevity of the cold rolled steel plate that holds the base of the cast iron baffles. It sits very close to the base of the fire. Time will tell I guess.
