We were able to exchange our remaining 4 tons of athens pellets with the distributor in our area in the past week. Sad to say the "new and improved" athens pellets produce no less ash than the ones we replaced. I will say they (finally) throw more heat, we can actually heat our home now without being on the highest setting continuously....but still *several* cups of ash to be vacuumed on a daily basis - can't go longer than 24 hours. Will just have to grin and bear it for the last 4 tons and pray we can find lignetics in the Spring!
