10 -20% savings with proper use of a setback or programable thermostat.
Most energy studies find or quote 5 to 8 degree ranges to save energy. Both heat and Air.
I saved my old Honeywell round dial and put that back on the wall when I came home and found my house at 82 degrees several Winters ago.
Turning it up and down when I leave and go to bed isn't so hard.
It would be nice to have the house warm before I get up again, but when I had a wood stove someone had to get up to a cold house and get a fire going every morning, too.
I look for decent instructions right on a flip panel on the thermostat.
(for the other two houses I take care of that both have multiple zones and programmable t-stats.)
