ok, help me out here. ( i must be tired) I understand the logic of heat rises. However, I put a thermometer up stairs just to see the different in temps with the diffferent air moving options I try. I can have it 80 °F down stairs and only about 69 or 70 upstairs. Today, I haven't really ran the stoves and my temps downstairs was 64 and temp upstairs 74. What sense does this make. I know without knowing the layout of my house, this maybe difficult to determine. The attic is right above the room I have the thermometer in if that says anything.
