Jams,

I really don't know as I think it must have to do with the house and the layout. People kept telling me to close off the vents to two rooms that I don't use much and I did it for 3 months and never noticed a bit of difference in my electric bill. But others say they have seen a difference, so it must be in the way the rooms are built and if they get really cold or something. My air mover has to push the same amount of air with the vents closed as it does with them open and it has those rooms shut off to draw from, so I have re-opened the vents and at least the rooms are warm when I do go into them.
