Here's my take on it.... If you have the time to cut the wood, or maybe you don't have the time, but are willing to spend the time, then get an OWB. My house is a little more than 5000 sq ft. I used to burn propane and spent at least 300 to 400 per month in LP. I was using it to run two furnaces for my house. I kept my thermostat at 68 and at night, went down to 60. My basement was always cold.
Now I heat my basement floor (I ran the lines when I built the house just in case) my garage floor and 2 heat exchangers for the furnaces. I go through about a cord every two weeks. Cut and split mixed and old dead wood. Anything I find laying down in my 20 acres of woods. If I had to buy the wood, I would still do it because I'd be at 300.00 per month, but I have a real warm basement, it stays about 77 or so, my main floor is always 74 and my garage is always 60. There's never ice or snow within about 1-2 feet of my garage door, and it just feels toasty warm in my house all the time, plus I love the smell of burning wood.
Now I could turn the thermostat down in the garage... I could also finish installing my thermostats in my basement to even that out a little, but I've gotten spoiled. You have a smaller house, and is probably better insulated than mine. You should go through less wood because of that. And if you cut your own wood, you will save a bunch of money. This is the first year Ive had to buy wood, but I'm still ahead of money.
I have a CB6048 and have no complaints at all about it , but I think pretty much any well known stove will be fine. I spent around 10,000.00 on my stove and all the extra stuff that it needed which includes all plumbing, both HX;s, rental of the trencher cement pad etc...
It should have paid for itself this season or next I can't remember.
Keep in mind though, I'm sure you realize it's alot of work to get all that wood and then there's all the loading and stuff. I load mine twice a day at 6 am and 6pm, but it's well worth it in my mind.
Good luck!
