I only have room in my shed for 2 tons, and I am certain I will need at least 1 more to get me thru the heating season. That said, I would like to purchase an additional ton should I come across a place that has some in stock, sooner than later. I have plenty of room in my cellar. The problem I have is I have a very high water table, thus a damp basement. It dries up entirely in the drier summer months and mid winter, but in the fall/early winter and early spring, my sup pump will run every few minutes. I am planning on buying a hygrometer to know exactly what the humidity is down there. I would store the pellets on pallets, raised off the slab on concrete blocks. Does anyone know what an acceptable high humidity threshold is? Has anyone any experience with storing in a damp basement? I have emailed the manufacturer, Lignetics, but haven't heard back yet.
