I ordered 4 20# bags of the char/hickory blend pellets before the NewYear. I was hoping for more heat due to the fact they had 20% charcoal in them. What I have noticed is they heat up very slow and do not produce the heat of a solid hickory or oak. These pellets are very long in length and I believe that I am not getting enough into the auger compared to a shorter pellet.
Also on my 055 Traeger, the flame feeds down the auger and gets my hopper smoldering, smoke spews out of it while grilling. I cleaned out my grill each time and this has happened 3 out of the 4 cooks I have done with them. I cant blame the pellet yet since I have noticed my firepot is starting to deteriorate letting more air in and may be the issue. I have another Traeger I will be using these in to see if it happens on this model also.
This is absolutely contrary to my experience with Char Hickory pellets. When I burned them, they very clearly had higher heat output... and while I could clearly smell the charcoal smell while they were burning, I personally did not notice any flavor that I could describe as better than 100% Hickory smoke produces.
On my PG500, with a typical wood pellet ( lets say 100% Hickory, from LumberJack ) , if I run the grill at a constant feed rate , where the auger runs for 1.5 seconds, then turns off for 13.5 seconds, I typically see temperatures around 180F on a day when ambient temperatures are around 72F. If I run LumberJack Char Hickory, at those same settings, with same conditions, I can't get my grill to run less than 225F.
So, I don't know exactly how you were trying to figure out if your Traeger got hotter or not, but your information is very different then my own experience with Char Hickory pellets...
