Stove temp mode will always give you a more steady consumption rate, however as stated above due to the control panel controlling only the exhaust temp the main factor affecting consumption will be the temperature of the room. The feed rate on Harmans is a max number only and the control panel decides how much to feed based on what you're asking from the stove.Not trying to accomplish anything really. Everything else is explained but what those numbers means to the user...other than a warmer environment. Though, it would be nice to know that if I set it on 4, I am burning 4 pounds and hour or 96 pounds a day or about 2.5 bags a day.
Not sure if the math is right though on the pound per hour. If it is a 50k btu pellet stove, 50k btu per hour and there are about 8700 btu per pound, then (my math) says something like 5.75 pounds per hour (that would be at full throttle, at least for that stove).
I know this isn't an exact science, just trying to figure the relation of those numbers to burn rate. With temp setting I know what I am getting, usage is based on room temp.
Thanks and thanks for the welcome!
In short there is no real accurate way to estimate this, it's always going to be variable. Howver if the temp outside remains reasonably steady i have found my consumption to be within a 1/3 of a bag day to day.
