I set my thermostat to 60 degrees and then use a space heater to heat the
office as that is the room I'm in mostly, and that works fine but I'm
wondering how much money it really saves instead of just setting it to 68
and leaving it there? I live near Chicago if that helps.

Thanks, Rich

It may be costing you. Electric in our area is at least four times the cost
of heating with oil or gas. YMMV so check out the different rates. I tried
doing something similar and all I did was increase my electric bill. Check
the comparative costs here
