Absolutely heed the advice about dry wood, minimum 2 years split and stacked in the sun for oak and hickory, less for most other woods, if you don't have that wood already, you may be screwed for this winter. Also buy a good stove top thermometer and learn how to use it, you'll get the longest steadiest burn times that way. You'll never hear the fan on low, and should never need it any higher.
Mine easily heats this ~1900sqft, although we're south of you, my only problem is getting the heat around the house, that's not the stove's fault. I posted a picture here last Winter at 14F outside, 84F in the room with the stove, toasty.
Loading N/S and raking coals forward will give you longest burn times, but it takes practice and patience. Don't expect to throw in some logs 5 minutes before you leave for work and expect to come home to leaping flames 9 hours later, but if you plan ahead, choose the splits well, reload 15-30 minutes before you leave, give enough time to adjust the air, then you'll come home to a hot house and easy relight.
Enjoy, if you have dry wood you won't regret the investment. If you buy "seasoned" wood from a dealer now, you'll probably curse this site all the way through 2013/2014. There are strategies to help deal with less than ideal wood, but they're, well, less than ideal.
