I have the furnace set to 65 at night and 70 during the day. The furnace isn't coming on much at night. I put a thermometer in the master bedroom. It's more than 10 degrees colder back there than out in the front of the house. I sleep in a recliner in the front of the house because of reflux issues. The wife can bundle up on 55 degree temps under quilts, I'm OK with that.
If you get to thinking you’re a person of some influence, try ordering somebody else’s dog around.
