Interesting review. Basically well insulated cookers vs minimal insulated cookers.This guy on youtube, I generally like his videos. Skip to the 16 minute and 22 second mark.
He compares a kamado Joe classic, the kamado pellet joe, traeger Pro 575, and traeger timberline 850.
Here's a down and dirty on the data in case no one wants to view the video.
Based on his test results ( the burn rate of the individual cookers), he then went ahead and calculated what it would cost in terms of the number of 20 lb bags per year based on 10 hours of cooking per week. And that 10 hours is based on one low and slow during the weekend, and one to two short Cooks during the week like steak or chicken.
Kamado Joe classic: 13.5 bags of big block lump (0.52 lb per hour)
Kamado pellet Joe: 13.6 bags of pellets (.52 lb per hour)
Traeger Pro 575: 25 bags of pellets (0.96 lb per hour)
Traeger timberline 850: 36 bags of pellets (1.38 lb per hour)
The 2 Kamado grills were very comparable lump vs pellet. Theses 2 seem like a good comparison lump vs pellet.
The 2 Traeger pellet grills are a good comparison of Kamado vs Pellet and the extra pellet weight it takes to use the 850 over the 575. Great read, thanks for posting.
