We decided to lower our thermostat this winter to see what effect it would have on our Progress Energy bill. Cutting it down to 64 degrees at the beginning of December proved to be quite chilly and we used our gas logs to help out. It was soon apparent after having to order another propane tank 3 weeks into the season, that using our logs daily to help out wasn't going to save us any money. It would take hours of running the gas logs to raise the temperature from 64 to 68 degrees, especially since our home's living room, dining room and kithen are open to each other. No partition walls between rooms means you have a greater area for the heat to dissipate and lose warmth(or at least it sure feels that way).
So, we upped the thermostat to 66. If we needed to turn on the logs to take the chill off, it of course didn't take as long to raise the temp up to 68. We started layering our clothes and have found 66 degrees to be quite tolerable by doing so. I put an electric radiator heater in the bathroom and turned it down to the lowest setting. Surprisingly it has done the trick to take the morning chill off when we shower.
Did we save any money? Well, yes we did. To the tune of $40 less this month compared to the same time last year and we did it during one of the coldest winters our area has had. The proofs in the pudding, lowering the temperature down a couple degrees has definitely saved us a few bucks this winter season.
