I'm finding conflicting answers to this, so I thought I'd go to you guys. Am I better off turning down my gas heat thermostat to 57 while I'm not home and turning it up to 70 while I am home.... or am I better off keeping it on maybe 62 while I'm away? Most days I'm only home about 4 hours before I head to bed and then I'd turn it back down to 57, so it's only keeping me toasty for those 4 hours. We've had plenty of 15-30 degree day time temps around here, so it's running all day no matter what. I'm in a 800 square feet house.
