I watched the inside temp and when it finally hit 63 I turned the heat on and set it for 67.Ofcourse some rooms are warm,and some(like the master) is an ice box.Oh well. Our gas bill for winter is usually in the $200's each month.
I've been turning it on in the morning long enough to take the chill off on cold mornings. Probably won't run it full time until November. We have no heat in our upstairs so running it at night doesn't really do us much good.
