i have a 2 story house with a wood stove insert in the livingroom /
diningroom. the stove has a blower. the room is approx 15x40'. it gets
very hot in that room and i'm trying to get the warm air to the second
floor. i can't cut vents in the ceiling as the 4 bedrooms are directly
above the main area and it would be too hot...

If the bedrooms are too cold now and "cutting vents" would make them
too warm, cutting smaller vents (or installing vents with dampers)
would make them "just right," no?

You will never get the even temperature of a typical house heating system

People like cooler bedrooms. How about 5 F less than the living room?

The cold air is coming down and the hot air is going up. Just not the
volumes you want.

It isn't hard to estimate the vent sizes needed to keep the bedrooms
65 F with a 70 F living room. Estimate the heat loss from the bedrooms
to the outdoors at 65 F... 880 ft^2 of R20 walls and 600 ft^2 of R40
ceiling would lose (65-30)(880/20+600/40) = 2065 Btu/h on a 30 F day.
And 2065 = 16.6Avsqrt(8')5^1.5 makes total vent area Av = 3.9 ft^2.

It was common to put floor vents above the stove and also at the other
end of the house. Ideally it was in a hallway. I'm told this is not
allowed by fire codes though.

We always have choices.
