So if you came in here to read that one is hot as hell and the other is like turning on the ac, hit the back button now.... First things first, temp readings were taken with 2 cooking probes, one a digital placed thru the middle slot of the heat exchanger and touching the metal on the top of the firebox, the other is a 12" long mechanical gauge inserted right of center, and not touching any of the metal surfaces. I used the 2 gauges this way as the air only gauge gave me an approximate temp of the output air, but is slow to react to temp changes, and the one touching the metal would show quickly any changes to adjustments being made. Stove was run on heat/blower settings of 9-9 and when adjustments were made they were allowed to run until the stove settled in, I would then back out and then go back to the changes to verify that it was the adjustment making the difference and not just a fluke. Ok with that said on to the results.... First up the Somersets, stove was run on factory fuel/air settings of 1-4-1 temps settled in between 300-315 digital, 200 mechanical, changed to 1-5-1, temps jumped to 325-335 digital, 210 mechanical, went to 1-6-1, hottest yet 335+ with a high of 352 on the digital, and 225 on the mechanical. Stove then ran for the next 24 hrs on the Somersets on hi/low off the thermostat. Got home from work tonight with 4 bags of Green supremes and started test two. Started at the Somersets hottest setting 1-6-1, stove maxed out at 290/180ish, so its true the GS pellets aren't anywhere close.... but wait.... went back to 1-5-1 temp jumps up to 315-320 digital and 200 mechanical, INTERESTING... go to 1-4-1, and, 330-340 digital 220 on the mechanical. This got me thinking, how many of the pellet tests on here were done at an optimal air/fuel setting for a particular pellet, and then tested another pellet at same setting only to report back that the second pellet sucked? Another thought was that with the CPM, clinkers or other build up really isn't a problem due to the stirrer, are some of these "inferior" pellets plugging the air holes on the burnpots of the pellet only stoves and creating a poorer burn that ends up as a low heat rating???? Ending thoughts.... If I had my choice between the two, at the same price, obviously I would, and did take the ton of Somersets, (only one my local blowes had) but at least in my stove there isn't a huge difference between the two.
