"Wood Henge" is about 96,000,000 Btu and I used about 155,000,000 Btu last year. I have 1.5 ton in garage. We keep house warm. They will stay there till used. I bring in 8 bags at a time. I'm putting another R22 in attic on the R30 something that is already there. We will see if we can bring the Btu's down some
I plan on adding more insulation as well. Problem I have is time. I have plenty of pellets for this year. Figured out last year where to have everything set to get the best efficiency. I used to pick up no more than 3 tons at a time, but now should be able to haul 5 to 6. Which should be plenty for myself, and anybody else in the family that needs pellets. Shouldn't have to make that trip till next summer.
