Deb, You need to put upward-facing fans in strategic spots to get the air circulating vertically. With 8' to 10' ceilings, the temperature in the upper two to three feet can be 15 degrees warmer than the floor. With 10' to 12' foot ceilings, it can be 20 degrees warmer. Nothing complicated; just small fans tucked in a corner here and there. Stairwells are logical places too, to circulate the air through the entire house. I've lived in big, drafty old houses and I've lived where houses are heated with wood stoves. I've also worked in greenhouses. Trust me, vertical circulation works. I've known people who reduced their heating bill by 30%, maybe more.
