I've read over and over on this forum about guys going through 4.5-6 tons per year. Some houses are smaller then mine and others are larger. This is my second year using coal and I'm on pace to burn around 9 tons each year. 9 TONS!? I heat around 1600' sq ft. The house was built in 1884. Its a single house, 18" thick stone walls all around, the attic has blown in insulation. But the 3rd floor is unheated.
I have an EFM coal stoker. Its settings are 6 teeth, or 15lbs per hour. I have the t-stat set at 67 day (6:30am - 7:30pm) 66(7:30pm - 10:00pm) 64(10pm-6:30am). I do have r30 insulation draped over the boiler to keep the heat in the boiler. The settings could be reduced to 5teeth (12.5lbs per hour), 4 teeth(10lbs per hour). But I fail to see how changing these settings would alter the result. If I use less coal, then the stoker will run longer to raise the water temperature. Am I running at optimul settings or am I doing something wrong?

But the boiler does have an air intake setting. I guess this is like a damper? I believe the aquastat is set to turn off at 200 degrees. Maybe 210? The lower setting is around 170 degrees. I'll double check tonight.
The 1st floor and 2nd floors are around 800sq ft each. The first floor has 12 windows and 3 exterior doors. The 2nd floor has 10 windows and 1 exterior door. (2nd floor porch). The 3rd floor (which is unheated) is around 350sq ft. Then there's insulation blown in over the 3rd floor.
Are my aquastat settings wrong?
p.s. I installed the coal boiler after 1 winter in this house with natural gas. In that winter, I was only heating part time. No kids. Now its full time.
