If I average 50 pounds a day at 80% it turns out to be just under 21,000 BTUs per hour to heat mine. Then subtract a little for the water coils, subtract a few percent for some coal going out with the ashes, subtract a little more for variable inefficiencies lol so probably closer to 18,000 BTUs per hour.

And if you apply my "Rule of 2.5" to your daily average you will pretty much know what you will burn on the single coldest day of the year. It will be around 2.5 times your annualized seasonal daily average.Lightning wrote: ↑Wed.

2.5 x 50 = 125 lbs. burned for the coldest nominal day(s) of the year. At ~80% efficiency overall that is about 51,000 BTUH on average for that day (with more than 51,000 during the night, and less than 51,000 during the day, averaging to 51,000 BTUH). Does that sound about right?

Yeah that's perfect. I normally have two or three 120-130 pound days. Most times they are consecutive days when we get a blast of arctic air and mean OATS are well below zero.

The results are in....
Since last Friday the 8th
6 days
390 pounds
65 pounds per day
40 pounds of ash.
It’s currently 5 OAT.

Sorry no outside air temp.
The average temp for today is 6. Hi of 11, low of 1. Not counting the useless windchill, says it feels like -2.

Larry, how accurate would you say it would be to gauge coal usage on ash motor time? As that is technically what feeds the coal.
If I put a hour meter on the ash motor to monitor its time cycles, and correspond that to coal fed per day.

I would think that should work quite well over the long haul. Your results may even inspire me to follow suit.hotblast1357 wrote: ↑Thu. Dec. 14, 2017 7:11 pmLarry, how accurate would you say it would be to gauge coal usage on ash motor time? As that is technically what feeds the coal.

My plan is to mount it in my control box if there is enough room.
