I bought a 55-shp10 about a week ago on clearance at lowes. I have been using it for a few days now to see how it heats, I have not run it all night yet but I start it at about five in the morning run it at 4-4 till it gets to about 70 than turn it down to 1-3 i am heating a little less than 1000 feet and even at that setting it drove me out of the house yesterday with the premier pellets I used it got to about 82 temps about 30 outside, after reading about trying other brands to see what burns best for you I tried lg today and it is only getting to about 76 same temp outside so is the premier a better pellet?
