(1) Find your thermostat “sweet spot” ““ that perfect degree that is just warm enough. Perhaps you could stand it a touch cooler, and just don't know it. Start by setting it two degrees lower than normal and see if you can go lower.
(2) Stop leaks. Put up window plastic; install door sweeps and weather-stripping on exterior doors.
(3) Cover exterior doors you don't use in winter. Slider door size “window” plastic will help trap heat, but still be quick to tear down in case of emergency.
(4) Hang heavier drapes over windows. Sturdy drapes keep cold out and warm in.
(5) Turn the heat down at least 1/2 hour before leaving, before bed, and when you are able to wrap up. Most homes retain heat for a while. Learn your home's heat retention time-frame and use it to your advantage.
(6) Only operate kitchen and bath vents when you really need them. They pull heat out of the home.
(7) Buy inexpensive slippers and actually wear them. (Or at least wear socks.) Keeping your feet warmer helps your whole body feel warmer.
(8) After using the oven, turn it off and leave the door open for a few minutes. (Of course, if you have small children, be careful with this tip.) The heat released as the oven cools will help warm the kitchen.
(9) Replace your furnace filter. A fresh one increases efficiency.
(10) Rearrange furniture to allow better airflow. Having furniture too close to vents can block, redirect, or absorb heat.
(11) Use more blankets. In addition to bed times, keep blankets handy for use whenever sitting – at the computer, watching TV, even during meals.
(12) Be old-fashioned and wear more layers. It's less expensive to pull things out of your closet and put them on, than it is to turn up the heat.
