I really appreciate anybody’s insight into this dilemma. I purchased a 3 level 2400 sq ft home (800 sq ft per floor).
My layout:
Basement is in ground and my furnace (aire-flo 80 eff) is also in basement. I have forced air in the basement and on the main level. I also have a gas fireplace (with no fan) on the main level. Baseboard heating upstairs.
Problem:
I’ll set my thermostat to 20 and it will feel great in the basement and main floor. But upstairs it is about 4 degrees different (crude test but my baseboard thermostat clicked on around 16 degrees). When walking upstairs to top floor you can almost feel cold air rushing down the stairwell.
Solution: the only things that I can think of are a ceiling fan upstairs to pull air up. Install a fan in fireplace to push air up the stairwell.
Thank you for reading this and am looking forward to seeing your responses
