Investing in energy-saving devices like programmable thermostats and ENERGY STAR®-qualified products, can save you money over the long run. Home energy efficiency also helps you do your part to protect the environment. This guide provides easy and inexpensive projects that can help reduce your home's energy costs.
Install Ceiling Fans
If you don't already have fans, installing them helps save energy and beautifies your home, which ultimately adds value.
Ceiling fans can help you save on energy costs year-round since they allow you to adjust your thermostat accordingly when they're running.
- In the summer, fan blades should revolve in a counterclockwise direction. Using ceiling fans in the summer allows you to raise the thermostat temperature, reducing the workload of your air conditioner.
- In the winter, set your ceiling fan to revolve in a clockwise direction. Set it at its slowest speed in order to gently push warm air down from the ceiling without generating a breeze. Then lower the thermostat temperature, reducing the workload of your heating unit.
Invest in Energy Saving Products
An investment in energy saving devices and products can save you money:
- Install programmable thermostats. They improve home energy efficiency by lowering energy use during those times when you are away from home or asleep.
- Replace single-pane windows with properly installed ENERGY STAR®-qualified windows. You can save up to $500 a year in energy costs.
- Use Light Emitting Diode (LED) or Compact Fluorescent (CFL) light bulbs. LEDs save up to 85% in energy costs and last up to 20 years; CFLs save up to 75% in energy costs and last up to 9 years.
- Replace appliances with ENERGY STAR®-qualified dishwashers, water heaters, refrigerators and washer and dryers for significant cost savings over their lifetime.
- Consider energy-efficient replacement doors for for maximum energy efficiency,
Insulate Your Water Heater
Insulate your water heater with a water heater blanket. For a small investment, you can significantly reduce the amount of heat lost by the unit, particularly if it is located in an unheated area.
Lower your water heater's thermostat setting to 120°F. Purchasing a timer help water heaters adjust to your water usage schedule.
Wrap Your Pipes
Do your water pipes pass through an unheated area? Wrapping your pipes is another inexpensive way to conserve energy.
Insulating your hot water pipes keeps them from losing heat. Insulating cold water pipes can prevent them from sweating and dripping in heated areas or freezing in unheated areas.
Replace Furnace Filters
Changing furnace filters conserves energy. Most furnace filters are inexpensive, disposable and easy to replace.
For optimal performance replace your furnace filter monthly. If you use the more expensive disposable filters designed to filter out allergens and extremely small particles, replace at least every three months.
Self-charging electrostatic filters that require no electricity are also available. Clean these filters by rinsing once a month.
Cover Windows and Seal Doors
Heat lost through windows and doors represents a significant chunk of most heating bills. Loss through windows alone could account for up to 35% of heating bills. Here are some ways to put that money back in your pocket:
- Caulk around the doorway to keep out drafts.
- Check windows and doors on a windy day with a candle or a light piece of thread to determine where drafts are and what areas need immediate attention.
- Remove and replace damaged caulk and weather stripping. Self-stick foam and rolled rubber weather stripping are easy to install and help create an energy-efficient house.
- Consider using inexpensive window weatherizing kits consisting of thin, clear plastic film and two-sided tape. After film is attached to two-sided tape, film is then stretched taut using heat from a blow dryer to remove wrinkles and creases.
- Use energy-efficient window treatments — closed shutters, window shades, blinds, curtains and lined draperies contribute to energy savings by helping to insulate windows.
Install Fireplace Dampers and Doors
A fireplace can rob your house of heat. Fortunately, there are solutions that allow you to enjoy your fireplace while minimizing heat loss. Here are some energy-saving tips:
- Consider adding a well-designed fireplace heater insert. These units come with blowers and thermostats. They are designed to significantly increase the heating efficiency while maintaining the classic fireplace atmosphere.
- Check to make sure that your damper is in good working order.
- Add glass doors to reduce heat loss as the fire dies down.
