I am in my 2nd season with a Harmon p35i. In warmer Temps (32 or so) I will run the stove on room temperature. Once it gets colder,I like to have it on stove temperature so that it doesn't start and stop all day. But this year, I am noticing that on stove temp, I can't get it to burn low enough. Feed rate is on 4. Temp dial is all the way down. I live in a split, the outside temp is in 20s and the house is 74. I don't need 74 and it is burning a bag a day. Last year I know that I was able to get a lower burn. Is it possible that the esp has anything to do with this?
