Greetings All, I have only had my Regency H2100 Hearth Heater for less than a month, but I have been burning wood pretty much every day since during the day (seldom overnight). It has recently come to my attention that my firewood has been wet; perhaps not all of it was wet as we did cut some dead-standing trees, but since I mixed the wood when it was being stacked I cannot recall what was wet and what was dry. Today I noticed a small, speckled, glowing ember-like movement across the back of the fireplace. It wasn't very large (maybe nine or ten glow points), but it slowing moved along the back of the stove until it, presumably, used up its fuel source. Was this creosote buildup within my wood stove that was simply burning up? There were no flames, but something was definitely burning/melting at the back. If this was creosote within my wood stove, should I be worried about creosote within my chimney lining even though I have only had the stove for less than a month? I am unable to get up on my roof to check my chimney, so I would have to call someone to do this, but do you think it is worth doing right now? Is it foolish of me to keep burning the wood I have when it will be a mixture of wet/dry wood? Finally, how can I tell if my wood is dry enough to safely burn if I am unaware of how long it has been seasoning. I have been told that the check marks on the end of the wood is a good sign to see if it is dry, but is this a reliable way of determining the greenness of the wood? Are there other ways of determining the dryness of wood? As well, I have read that different types of wood require more/less drying time than other types of wood, but everyone seems to recommend one year of seasoning. Is this the safe bet? Thank you all for your responses and helping me figure out how to best use my stove. Cheers.
