How many of you guys out there have had experience with pellet furnaces? I am looking into a Harman PF100 for my new home I am building next year. I don't have natural gas available to me and if I do use propane, I have to bury the tank. If that is the case, then I have to buy it. In my area, things are super expensive. That alone is $3500. So I am thinking about a forced air heating system with this pellet furnace, but I have not found a whole lot of reviews online about them. I hear Harman is supposed to be good brand, but not much info out there on there furnaces. Plenty of reviews on the stoves, just not furnaces. I was planning on installing a backup electric coil downstream of the furnace, just in case I ever had a problem with the furnace and it went down for a short time period. Any personal experience would be gladly appreciated!!!
