Delmarva Power recommends customers take advantage of the mild weather now to prepare for the winter months ahead. Cold temperatures during the winter can cause customers to use more energy and experience higher bills, but by following a few simple tips and making straightforward energy efficiency improvements during the fall, customers could save 20 percent or more on their winter heating bills.

• Keep it sealed. A poorly sealed house is costlier to keep warm. Caulk around doors, windows, and any openings for utility services. Using the locks on your windows helps make a tighter seal that is more resistant to drafts. If you have a fireplace, keep your damper closed when the fireplace is not in use.
• Upgrade your insulation. Insulating your home can significantly reduce your heating costs, while also increasing the comfort of your home. Reducing air leaks – around floors, walls, ceilings, ducts, fireplaces, doors, windows, vents, and plumbing – could cut your home’s average monthly energy bill by 10 percent.
• Check ducts for air leaks. Look for joints that are no longer connected. Leaky ductwork can increase your energy bill significantly.
• Warm up your system. Service your heating system before winter begins. A well-maintained system will last longer, operate more efficiently, and save you money. The potential for carbon monoxide exposure is possible if home heating equipment is not properly tested, serviced, and maintained.
• Manage your thermostat. Keep thermostats set at a comfortable level. You can save about two percent on your heating bill for every degree you lower your thermostat. When you are asleep or out of the house, try turning your thermostat back 10 to 15 degrees for eight hours to save approximately 10 percent on your heating bill. Consider investing in a smart thermostat that can connect to your mobile devices, helping you stay on top of your energy usage.
• Be prepared for cooler weather. Remove screens and air conditioners from windows and install storm windows.
• Take advantage of the sun’s heat. Open curtains on your south-facing windows during the day to allow sunlight to naturally heat your home and close them at night to reduce the chill from cold windows.
• Shorter days and longer lights. Adjust outdoor lighting timers as the nights grow longer. Replace older incandescent bulbs with new energy efficient LED bulbs.
