We live in Maryland and are trying to find the best type of pellet to burn in our Harman Insert. We have used 2 tons Lignetics but they didn't seem to have much heat out put on the really, really cold days, they did well on the milder days. We are currently burning a ton of O'Malleys...love the heat out put hate the fact that I need to empty the ash pan every 2 days...they burn really dirty! Any suggestions? I've also been told to try Hamer's or Turmans but havn't been able to find a dealer in the Annapolis area. We are willing to drive if necessary.
