Save Money on Your Heating Bills

In most parts of the country, it’s time to turn on the heat.  On average, each American household spends over $500 a year on heating.  Regardless of how old your home is, there are some things you can do to save energy.  According to Allison Rutter on Green Yahoo  “by paying attention to your building envelope, your heating system, and your behavior, you’ll be well on your way to saving dollars and carbon.” She offers the following money saving tips on Yahoo Green.

Sealing the envelope
Your home’s envelope (the walls, windows, doors, foundation, roof, attic, etc.) matters a lot when it comes to heating.
Leaky envelopes mean cold outside air can easily seep inside. Warming this inflow of cold air can account for 25-40 percent of the load on your heating system.
To improve your envelope, try:
Discovering where your leaks are. A professional can administer a “blower door test” to find out where envelope leaks originate. For an inexpensive option, try holding incense near places where different materials meet, such as window frames and where the walls meet the floor. Send your buddy outside to sniff for any potential gaps.
Caulking and weather-stripping cracks and holes. These materials can be found at any hardware store, and a store expert can guide you to the best materials for your house.
Plastic-wrapping your windows. Not the kind that covers your leftovers, but a shrink wrap version that stretches over window glass and frames to seal warm air in and cold air out.
Using door snakes. Less scary than they sound, door snakes can block air from traveling under your doorjambs. Try the traditional fabric-filled kind or rubber versions sold in hardware stores throughout the country.

Looking to make greater changes? Consider:
Replacing your windows. New energy-efficient windows sport higher levels of insulation.
If replacing windows is too expensive, consider storm windows. According to EERE, interior or exterior storm windows can reduce the heat loss through your existing windows by 25 - 50 percent.
Adding more insulation to your envelope. See how one of my employee’s upgraded her old Victorian house to be 311 percent more efficient with the help of insulation.
Enhancing your heating system In addition to these measures, you can improve the efficiency of your heating system by:

  • Insulating heating ducts. This keeps air warm and minimizes leaks while transferring air from your furnace to your rooms.
  • Keeping your systems maintained regularly. When your air filters are replaced consistently, air can flow more freely. Plus, an expert can ensure your system is working at its optimum performance.
  • Unblocking vents. Help the warm air travel throughout your house. Don’t block air vents with couches or drapes; doing so traps the air and doesn’t let it circulate.
  • If your furnace is older than 10-15 years or your boiler is older than 20 years, then a new heating system will be at least 30 percent more efficient and will pay for itself in 5-10 years. The American Council for an Energy-Efficient Economy has detailed information to help you determine whether to replace your furnace or boiler, find a good contractor, size your heating system, and calculate your return on investment.

Changing your behavior. Some of the most substantial energy savings can come from small habit adjustments like:

  • Consciously setting your thermostat. Would you be comfortable if it were three degrees cooler? By paying attention to your set points, you can save up to $180 a year. If this seems tedious, consider a programmable thermostat. EnergyStar offers a calculator that estimates savings.
  • It may seem obvious, but keep your windows and doors closed.
  • Layering! Though we can’t grow a thicker coat of fur, we can wear layers of clothing, and add to or take layers off to suit our needs. This method of “adaptive thermal comfort” is easy to do, and lets you get more use of all those clothes in your closet.
