I'm in a tiny rental house-built within the last 20 years and is pretty tight. 1K sq ft upstairs and it is heated by the wood stove only. It's a small all steel instead of cast iron stove, so it warms up quick but also drops off quick. It has electric heat as a backup that I set at 50 and it never comes on.

Edit to add, no circulation needed due to the layout of the house. The general theory with circulation is push the denser cold air towards the heated part.

The downstairs(house is on a slab so it's a garage) is another 1K sq ft with all the water stuff and laundry room. It is heated by electric garage heaters. Those heaters are crazy expensive to run.

Downstairs is set at 50 with the temp checked a few times a day, upstairs is whatever the woodstove feels like doing. See the above post of the guy at 91. With the exception of just before bed time, I try to keep it in the 70s but sometimes it gets nuts.

I'm having a 1400 sq ft house built in Coös County. The basement will be oil fired radiant heat in the floor. So will the main floor, but I plan on heating it with a wood stove and using oil as the backup. I have a Hearthstone Green Mountain 60 sitting at the dealer, waiting for my builder to be ready for it. I may need to use some sort of circulation to move heat around. I'll find out next winter.
