I know there's alot of people burning wood pallets , I have pretty good access to get them for free , are they worth the work or do they burn up to fast . I thought they would be good in the spring and fall when you don't need alot of heat and on weekends when your around to tend to the stove more often . I would think they would burn pretty fast and hot !!!! Also was wondering about the nails , whether they would get stuck in the grates ?? Any ideas??
