I doubt you'll ever get 12 hours using sub bit coal. 3-4 hrs is about right with decent sub bit. The only way you'll ever get 12hrs out of that furnace is by using anthracite or good Kentucky lump bit coal. That's just the way of the world, the nature of the beast etc... The only guys getting those burn and shake times are NOT using sub bit. Sorry to be the bearer of bad news, but you need to know what you're chasing is not really viable with that fuel.
You can easily get 12 hours out of sub-bit. I burn sub bit and can easily get 12 hours between fillings. You just need to have a stove that is large enought that you can bank the coal well and allow the fire to burn through it slowly. This won't happen if you have a stove that is just large enough for the area you are heating. With my experience with sub bit, it helps to have a stove that is a little larger for your house rather than just right or too small. I heat about 1800 SQ feet with a vogelzang norseman which is very similiar to a hotblast. It will hold 100 lbs of coal and if you heap it good you could probably squeeze in 125lbs.
