◆ Install an automatic setback thermostat that adjusts room temperature according to your daily schedule. If you have a heat pump, be certain to use a special thermostat designed specifically for heat pumps.
◆ Install do-it-yourself weather stripping and caulking to seal air leaks. Seal all perimeter wall penetrations and ceiling and floor penetrations to stop all air movement between heated and unheated spaces.
◆ Install do-it-yourself storm windows that cost less than $1/sq.ft. such as flexible vinyl glazing.
◆ Use motion sensors or timers for outdoor lighting. You’ll still have security and save energy.
◆ Replace incandescent light bulbs in common areas (where lights are on most of the time) with compact fluorescent lamps (CFLs). They use about a quarter of the energy.
◆ Replace the halogen torchiere floor lamp with a CFL model. They’re safer, use 70 percent less electricity and produce as much, if not more, light.
◆ Tune up the furnace annually.
◆ Replace furnace filters. The dirtier they are, the harder the fan furnace works. Clean filters are essential for heat pumps – airflow is critical and can add years to the life of your heat pump.
◆ Add water heater tank and hot water pipe insulation especially if in an unheated space. Don’t cover the thermostat or, for natural gas models, the air inlets.
◆ Install a sheet metal fireplace cover, especially if the flue damper does not fit tightly
