Both the Enviro Maxx at home and the Harman PB105 at the in-laws accumulate hard black deposits in the firepot that have to be scraped off weekly to maintain a good flame. These deposits are HARD - especially on the Maxx, where sometimes I have had to resort to a cold chisel & hammer to remove them. For a long time I assumed that this material was carbon, but recently I questioned that, and began to suspect that it must be minerals. If it was carbon, why wouldn't it just burn up?
Does anybody know the scientific facts? Is there anything to the idea that different pellets might have an effect on this, or is that just folklore? Have been burning hardwood pellets: Northern or New England. Some say softwood pellets produce softer ash, but does that relate to this type of deposit in any way?
TIA
