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.

Our blower will not shut off!!! Do we need a new thermostat? If so, is this easy to install ourselves? ( I am asking - my husband will be doing the repairs if needed)
Has anyone else had a problem like this?

This furnace is about 3 months old.

Are you referring to the big blowers on the back that force your heat into the duct work, or the small induction blower on the middle-back of the furnace?

If it's the big blowers, and no one has added the induction blower kit (furnace is bone stock), the on the back, top left of the furnace is a black or green cover held on by 4 10mm bolts... under that cover is what's called a thermo-disc... this is what controls when the blowers turn on/off and more than likely this is what needs replaced... VERY easy to do, just unscrew it, and there's two wires going to tabs on it... the clips just slide off, slide on the new thermo-disc, and put your screws back in, then the cover....

Now, IF in this spot you have a silver cover that just sorta 'snaps' on, remove that and if there is a round disc behind said cover with three small tabs, then follow what buffalo bob said. The device he's referring too is called a Fan Limit Control and typically with the hotblasts they were not factory installed unless you had the induction kit installed.
