Is it expensive? Where would you get it??
I know coal and coke used to be sold from the same dealers around here anyway. I've seen old newspaper ads and such.
I found this little bit on Wikipedia.
Some cokemaking processes produce valuable byproducts, including coal tar, ammonia, light oils, and coal gas.
So maybe if you were coking coal to produce those other things then coke is basically a waste product that can be sold cheaper but it still has value because the coke can be used to make heat for other uses.
That's just a guess on my part. Maybe someone else has a better explanation.
I have to say that it seems to be slightly hotter than coal in my extremely limited experience. Normally, the house drops to ~64* over night when the outside temp is in the 20's but I got up this morning and it was ~68* with the air intake set the same as where I normally have it.
I just gave it another 1/4 turn open to see if the fire recovers at all. It seemed pretty low but still making good heat. I didn't shake it yet but will in about an hour. I'm interested to see if there is more or less ash.
From playing around with it the other day, it seems like the individual pieces don't break down like coal does. A couple pieces fell out of the firebox when I was poking through the pile to break up some ash and after sitting on the concrete a few minutes, they went from orange to black and looked exactly like it did when I put it in.
