Feeling the Heat

I am doing some research to install a stove on the first floor of my 2-story colonial, which also has a finished basement. If I turn off the furnace in the basement, it will stabilize around 55 F. That's a little too cool for comfort for the kids playing down there. I currently have an oversized Dutchwest stove in the basement, and experiments to get that heat upstairs have been unsuccessful: https://www.hearth.com/talk/threads...-distributing-heat.151712/page-2#post-2067343

I would like the main-floor stove to keep that floor at 70, with the basement and second-floor bedrooms at 65. Is that realistic? Of course I could run the furnace to bring the basement from 55 to 65, but that would cut into the cost savings of wood heat.

So, those of you with a similar setup, do you successfully heat your finished basement from the floor above, or run the furnace, or just let it stay cool? What sort of temperature differentials do you achieve between floors, and do you use any fans to assist?
 
I find when I'm burning my unit on the main floor I turn on the hvac fan. It seems to level things out throughout. This works very well in shoulder season and when not too cold in winter. When we are in the thick of winter it won't keep up and I have to run my electric forced air furnace or my wood furnace in the basement. Only time I need to run both the main floor and basement unit is when we get past -35c so not very often. 3200sq ft house with basement. Basement partially finished. 26 yr old house, original Windows which are getting drafty seals.
Depending on the size of your house
And insulation/Windows stove may not have enough btu's for you.
 
You really aren't going to get heat from the first floor down to the basement without your HVAC. I have a BK ashford 30 in my finished basement and the heat migrates very well to my first and second stories. My steps to go up a level are across the room from the stove and the stairs to go up to the second story are directly above the first set.

The second floor stays nice for sleeping (65•) but that is probably only because of how well i insulated up there. It's also a cape so slanted ceiling and indhlstef knee walls so the only place I have exterior walls up there are the gable ends.

I also cut an old floor register from an 1800s era Philadelphia home into the floor directly above my stove. This moves SO much heat from the badent to my first floor. Pretty sure it's a safety hazard but it sure as hell helps with heating my house.
 
I've been wondering the same. Right now my basement drops well below 55 in winter, and the big smoke dragon down there can sort of heat it but even with it cranking the heat doesn't migrate to the upper floors very well. It chews through the wood, and I don't use the basement much, so I just let it get cold. But in a future house I'd really like to get back to a one-stove solution and one that will work for all three levels if I go that route. I think I'd prefer a house with basement and sloped walls in the upstairs - partly for cheaper taxes. If I was designing one built I'd probably use oversized and unshrouded stairways to allow heat to more easily flow and not get trapped anywhere.
