Agreed and leaving max displayed at a 40 feed rate keeps it feeding at 40. (45 seconds out of 120)
I should run the test again but it seems the 110,000 BTU rating is with the feed motor running all the time.
I have an old triple beam scale and got 4.18 lbs in an hour at 40, 51414 total BTUs -25% gets me 38560 BTUs of heat out of the stove. I'm not sure what the thermal efficiency of modern stokers is but I think the combustion efficiency is 80-90%
At 20 I get 2.15 lbs. in an hour, 26445 total BTUs -25% gets me 19833 BTUs of heat out of the stove.
A 10 I get 1 lb. in an hour, 12300 total BTUs -25% gets me 9225 BTUs of heat out of the stove.
