I love these kids of threads!
Your decision can be easily answered with just a few secondary questions because these two stoves are quite different! 1. Do you want stainless steel or carbon steel? 2. Do you want natural draft or forced air? 3. Do you want to be able to burn coal? 4. Do you want to pay $12-$13 thousand or less than $10,000?
I'm heating 3,000 aft of terribly insulated house, 800 Sft of garage, domestic water, and my hot tub. I still have room for the bonus room above the garage when I get that exchanger hooked up. I'm only into my first season, so I don't have very good wood consumption estimates. I've never had to load more than twice in one day, and I've burned some seriously junk wood.
I strongly endorse Heatmaster. I love my stove simply because of the design. I think CB makes a quality stove, but I just can't get past their salty prices. I just don't think they are worth what they charge. I think P&M boilers are in their price range and offer a better product.
