Eddie, you are not that much north of me and I also have an open concept home, similar size, electric baseboards and no basement. When we built 30 years ago, we looked at propane and heat pumps and both were expensive and with many drawbacks. We put in a mid-sized Vermont Castings wood stove and we save at least $1,000 per winter on heat. At first, I had to buy wood and used the stove less but now I have abundant wood and it is on 24-7. Our VC is 2.4 cu ft and it is great to supplement but not as a sole heat source.
Last winter was brutally cold for all of us and the VC has had a great life but needed to be replaced. There are lots of great buys on larger stoves on Kijiji if you take the time and effort to search and the time to research. A PE Summit will heat your home very well, as will a Blaze King King, a larger Regency, etc. I have seen all of these used on kijiji except the King and I bought a Hearthstone Equinox at half of new $$ a few weeks ago. If you have the $$, there are lots of dealers near you but shop around and do your research first. I bet you are burning softwood and that is why you are not getting a long burn. Even the ancient VC I have will still have lots of coals in the morning after a night of burning well dried oak or maple.
Personally, I know a lot of people with inserts and I considered a ZC fireplace but a stove will give you the heat you need. Any larger (3 cu ft +) stove will heat your home. Get a ceiling fan and turn it on very low to get the heat circulating.[/quote
