I am burning reading coal in a hand fired Fire Chief furnace and it seems like I will get 10 or so bags of coal every now and then that does just not seem to have as much heat in them. I seem to have to open the damper up and run the stove harder than other times last night it was zero here and I had the damper just cracked and furnace did fine earlier in the week it was in the lower 20's and I had to have the damper open almost all the way. Does any one else run into this?

The weather conditions have a lot to do with how well coal

burns and the perceived heat it puts out. A cold day with no wind

and a low barometric pressure seems to lower the heat output ,

more than anything else.

Heating appliances work best with a steady draft and fuel supply ,

disrupt any of those and your results will vary quite a bit.

Its usually some other factor not the coal , which is pretty consistent

in BTU but maybe not in its volatile content or ash content.

A barometric damper can take one variable out of the equation by

supplying a consistent draft under nearly all weather conditions.

It could be like the TSC coal and every once in a while a bag has more fines in it, or is wetter, slowing it down. Just a couple other things besides what Barney listed.

Recently purchased Reading and find it very consistent. In my stove after 5-7 days it does become ash bound and needs the grates sliced which is better than some which clog sooner. Reading seems dry so may not be washed like TSC and others?

I have posted on here earlier that I dont think Reading Coal today is the Reading Coal of yester-year....My father had a trucking company and 1 of his contracts was coal...back then Reading Coal was awesome as we used to heat the uninsulated workshop my dad had....heated well, I bought it about 3 years ago and burned like crap and ashed my stove closed.....Blaschalk never does this as I light in Nov and turn off in March...now I have a stoker with rice coal so I know they usually have a tendency to produce more ash....But never with Blaschalk...
