From the Forums: Programming Your Thermostat
camerson wants to know:
Is there a good way to determine how I should program my thermostat for maximum efficiency? I've only had my new thermostat for about 6 months but I'm not sure I can see a real difference.
My wife and I both work at home. During the day we keep the heat at about 68º. After 6pm we like to snuggle at about 71º, but we only heat the living room/kitchen via the gas fireplace about that time. At night we crawl into a warm electric blanket and the thermostat turns down to about 62º at 10pm (as low as 55º in early/late winter).
The simple act of lowering the thermostat for 8 hours at night can save you 1%-3% in energy for every degree you drop. Turning your thermostat from 72º to 65º eight hours a day can save as much as 10% on your annual heating costs.
