Apologies in advice, as I have not read through the entire thread.
I would roast if my thermostat were set anywhere near 63. Mine has been set at 46 for the last few weeks. Before that, it was set at 56ish, but then Bakari's postings inspired me to go lower.
This morning, I tried to set the thermostat even lower, but it apparently does not go below 45!! So I turned it off. Around the house, I routinely wear warm socks, down booties, long johns, cotton sweat pants, a few layers of shirts, a Buff around my neck, a Turtle Fur hat, a down jacket, and wool fingerless gloves. Right now, in this getup, I am too warm. It is 53 degrees in my house.
Hard to know how much $$ I have saved, because my utilities are tied to those of my rental house, and my tenant has his thermostat set at a crazy 68 degrees. But, the total savings for the last 3 months compared to these 3 months last year is $70. It also helps that I had new insulation put in the rental house.
