Lets Talk Numbers

A Coal stoker furnace or stove controls most operations including automatically feeding the coal. They are quite similar to any conventional oil and gas units and easily operated for extended periods of time. They commonly use rice coal but may use larger sizes like buckwheat. They can be used as primary heat, supplementary heat or have a dual set up with your existing oil/gas furnace.

Like Isayre my Jan. consumption will be around 1750 lbs. , I hit 2 ton on Jan. 20 with a start up on Oct. 9 . I am very happy with the 110 performance .

Around 2 here this am plus the wind. Barn/shop area steady at 68- stove temp 550- no clue what I am burning only that
it burned half a bin over night- 50lbs maybe. No oil or gas, coal only heat source, it's working great, and it is cheap. Life is
good :D Aside from being really warm, the next bonus of coal is not thinking about cost. On oil, I used to obsess over usage,
supply etc. Now I do not even think about it- I've been set free!

About as free as we can be in MA. ;)

Hit -4° last night for the low early in the morning. Cranked the Harman to 3 turns out yesterday afternoon around 15:00, fire was burning good by 16:00. Side at one point was 750° and rising. Pipe 300° right at the stove outlet. My drafty house got up to 63°. That load has been burning for 18 hours now, so it's starting to taper downward. House has dropped to 60° while the outdoor temp has hit 10°. Usually burn about 60-65 lbs.a day (est.). Today will be double that.

More numbers:

This winter season (to date) I'm averaging 1.47 lbs. of coal burned per HDD (Heating Degree Day) while burning Harmony pea. Last winter for the entire season my average was 1.57 lbs. per HDD while burning primarily a 2/3 Blaschak and 1/3 (presumed to be) Stockton blend.

Democracy rests upon the principle that collective wisdom arises from a pool of individual ignorance. A Republic rests squarely upon objective law, and fundamentally upon those laws which restrict the scope and actions of government.

I am using about 200# of coal every 24 hours during this cold period compared to the 120# during the warmer weather. I feel I am burning more coal than many others but still very happy that I am not using oil.
