Since I hit the one ton point, decided I should see how much ash I'm getting. Snowed yesterday, top of the driveway was a little slippery. Dumped the ash pan into the bucket so I could be totally accurate. Weighed the ash bucket, which contains all the ashes since I started burning, strewed the ashes in the driveway, weighed the empty bucket. 13 lb. of ash from 1 ton of pellets, half Energex, half Pennington. I make it to be .65%. Energex bags say less than 1% ash, Pennington just says "low ash". Just thought it was interesting.
