Welcome to the forum. I am a new full time coalologist this year and I am also burning pellets and have been the last 3 years. I have been heating a 1300 sqft raised ranch wth a Breckwell Big E in the kitchen and going through 3 ton a year keeping house at 72-78 deg but my basement is not finished and I hated to go downstairs to 50 deg temps.
The last two years I have been burning coal on a part time basis in the basement on the weekends for the kids play down there. They could go down there and ride scooters, roller blades and pogo sticks. The older Alaska stoker stove I had down there was old and I went through alot of coal with it but it was 75 deg down there. One thing I noticed was my pellet stove upstairs worked alot less when the stove was on in the basement.
Long story short, this year i bought a used 01 Harman Mag Stoker for $1000 ( from a guy in Keene) and I absolutely love it. I have heard horrible things about Harman as a company from when I was pellet stove shopping years back. I would not buy a new Harman because of the things I heard. I actually looked a few years back at coal and came very close to buying an Alaska (I love the looks of them)
It has not been very cold yet here but theHarman stoker is keeping my entire house, including the basement at 72 deg and the stove is running at a pretty low setting. My pellet stove is feeling extremely neglected.
I apologize if I am rambling here but...when it comes down to it..... I should have bought a coal stove to begin with.
FYI if you are up for a ride:

seems to be a great deal, I drove 1.75 hours for my Harman
A friend of mine said he would buy a ton of pellets off me. Sounds like a good op for me to get a ton of coal.
As for the carbon footprint A question I have to the experts on this forum is:
Don't home heaters burn coal alot more complete and efficient than the large industrial plants?
My newbie advise? used coal stove
OK I will now shut up as this must be a record post.

Sorry
