Being fairly new to pellets and being an old time wood burner 30yrs. I really havent had the opportunity to check out some of the pellets ive read about on this forum.

I may have burned a little more because more was going through the auger but at at feed rate of 1 fan of 5 38 degrees my little Summmer heat 1500 had the house cranked
