You can stay warm for less this winter  by making energy-smart improvements and easy adjustments to your household routine.
Here are eight ways to stay warm this winter while spending less green:
Seal out drafts: Eliminate air leaks and drafts  around the house, and you’ll trim seasonal heating costs by up to 20 percent. Sealant, caulking and weatherstripping are all easy to use.
Insulate heating ducts: Keep the warmth of your forced-air heating system moving in the right direction by sealing and insulating ductwork . Pay special attention to ductwork in unheated areas like attics, crawlspaces and garages, giving it a wrap with insulation that has an R-Value of 6 or higher.
Schedule a tune-up: Natural gas, propane of oil heating systems  creat combustion deposits when they burn that build up and can make the system both unsafe and ineffcient. Get the most out of your heating equipment by having it serviced at least once a year by a qualified professional.
Clean furnace filters: Dirty filters slow air flow and make your heating system work harder, so ensure efficient delivery by checking and changing filters monthly during the heating season.
Program for warmth: Install a programmable thermostat  and set it conserve heat while you’re away from home, then warm things up before you return.
Trim the cost of heating water: Keep your hot water heater’s temperature at 110 degrees, and insulate the tank  according to manufacturer instructions. Check out the U.S. Department of Energy’s Energy Saver Guide  for more details.
Get free heat: During the day, open shades and curtains on west- and south-facing windows to usher in the sun’s natural warmth, then close them once night falls.
