10 Common Heating Mistakes

Here are some useful, eye-opening tips on 10 common mistakes to avoid when heating your home.

1. Maintaining a constant temperature

Cause: A persistent myth suggests that you can save energy by leaving the house at a comfortable 68 degrees (a widely recommended winter setting), even when you are sleeping or away at work.

The idea is that it takes more energy for the furnace to reach a comfortable temperature than to maintain that temperature.

Effect: You could miss out on significant potential energy savings by not using a programmable thermostat and adjusting the temperature overnight and during the workday.

Though the impacts of adjusting the thermostat vary based on your climate and other factors, studies show that knocking the temperature down by 10 degrees for eight hours per day can cut heating bills by 5 to 15 percent.

Sure, the furnace will cycle on for a longer period to return to the more comfortable temperature, but it will be far outweighed by hours of savings when it didn’t have to work as hard.

2. Cranking up the temperature to warm up the house

Cause: You come home in the middle of the day to a cold house. You want to warm back up to 68 ASAP, so you crank the dial up to 78 to get the furnace working harder and faster.

Effect: No time is saved in reheating the house. Most furnaces pump out heat at the same rate no matter the temperature. They just cycle on for a longer period to reach a higher temperature.

The furnace will take the same amount of time to return to 68 degrees regardless of the thermostat setting. By cranking up the thermostat, you are likely to overheat the house past 68 degrees and waste energy. Just reset the thermostat to 68, make some hot chocolate, and wait.

3. Closing off vents in unused rooms

Cause: You don’t want to waste energy heating rooms you aren’t using.

Effect: Again, this just wastes energy and makes your furnace run inefficiently because it changes the air pressure in the whole system.

Experts recommend never shutting off more than 10 percent of vents. Sealing your ducts is a more efficient way to save energy.

4. Using the fireplace

Cause: You found some free firewood on Craigslist and think you can burn up some free heating energy while enjoying a romantic fire.

Effect: While we can’t make any promises about increased romance, we can predict increased energy bills. An open fireplace flue may suck more cold air into the house than the fire can radiate into the living space.

5. Using electric room heaters

Cause: You spend most of your time in a couple of rooms, so you figure you will just heat them with space heaters.

Effect: This could lead to higher energy bills and greater fire risks. Generally, a central gas heating system is cheaper and more efficient than a set of electric room heaters. Electric heaters also can be a fire hazard.

There are exceptions. A single energy-efficient space heater in a small, well-insulated room can save energy if the central heater is switched off.

6. Switching to electric heating

Cause: Electric heaters are more efficient than fuel-based systems, so they must be cheaper and better for the environment, according to this popular idea.

Effect: In most areas, simply switching to electric heat leads to higher energy bills and a bigger carbon footprint. Your heater may be more efficient, but most U.S. homes are still linked to coal-fired power plants. These coal plants and their transmission systems are extremely inefficient.

Of course, it’s a different story if you have a large photovoltaic solar array or your utility company uses renewable energy.

7. Replacing the windows

Cause: Those big pieces of glass get so darn cold. They must be the reason your house is so drafty.

Effect: You could spend a lot of money to only take care of part of the problem. Windows must be installed properly to avoid drafts, gaps, and leaks.

Moreover, more heat is typically lost through poorly insulated walls and ceilings than through windows.

8. Replacing the furnace first

Cause: You blame high energy bills on an old, inefficient furnace.

Effect: Your energy bills will still be higher than necessary if you don’t start with cheaper, smaller upgrades to improve the energy efficiency of your home, such as caulking around windows and doors and adding insulation.

9. Upgrading to the most efficient furnace on the market

Cause: You want the sleekest, most energy-efficient furnace available because it will be the most cost effective as well.

Effect: You may end up replacing an over-sized furnace with another (albeit more efficient) over-sized furnace. The U.S. Department of Energy reports that most U.S. homes have over-sized HVAC systems.

Again, insulate and weatherize to maximize efficiency, then get the smallest system that will comfortably meet your heating needs, which will be substantially reduced. Also make sure it is professionally installed.

10. Using incandescent light bulbs for heating

Cause: Incandescent bulbs give off more heat than light, so they must be warming up the house.

Effect: It is hard to see this logic as anything but a weak excuse for holding on to the Edison bulbs rather than switching to CFL and LED lighting.

In fact, one German entrepreneur is marketing incandescent bulbs as “heat balls” to skirt EU laws against the old-style bulbs. However, I doubt he is keeping cozy this winter simply by sleeping with the lights on.

CFLs contain a small amount of mercury sealed within the glass tubing. Here are some detailed instructions from the Environmental Protection Agency on how to safely clean up and dispose of a broken CFL bulb:

Before Cleanup: Air Out the Room

  • Have people and pets leave the room, and don’t let anyone walk through the breakage area on their way out.
  • Open a window and leave the room for 15 minutes or more.
  • Shut off the central forced-air heating/air conditioning system, if you have one.

Cleanup Steps for Hard Surfaces

  • Carefully scoop up glass pieces and powder using stiff paper or cardboard and place them in a glass jar with metal lid (such as a canning jar) or in a sealed plastic bag.
  • Use sticky tape, such as duct tape, to pick up any remaining small glass fragments and powder.
  • Wipe the area clean with damp paper towels or disposable wet wipes. Place towels in the glass jar or plastic bag.
  • Do not use a vacuum or broom to clean up the broken bulb on hard surfaces.

Cleanup Steps for Carpeting or Rug

  • Carefully pick up glass fragments and place them in a glass jar with metal lid (such as a canning jar) or in a sealed plastic bag.
  • Use sticky tape, such as duct tape, to pick up any remaining small glass fragments and powder.
  • If vacuuming is needed after all visible materials are removed, vacuum the area where the bulb was broken.
  • Remove the vacuum bag (or empty and wipe the canister), and put the bag or vacuum debris in a sealed plastic bag.

Disposal of Cleanup Materials

  • Immediately place all clean-up materials outdoors in a trash container or protected area for the next normal trash pickup.
  • Wash your hands after disposing of the jars or plastic bags containing clean-up materials.
  • Check with your local or state government about disposal requirements in your specific area. Some states do not allow such trash disposal. Instead, they require that broken and unbroken mercury-containing bulbs be taken to a local recycling center.

Get Your Kids Involved in Saving Energy

Getting your kids excited about saving energy helps them adopt lifelong values about energy use, money, and the environment. By turning energy-saving tasks into games, you can make learning about energy fun and easy.

Bring home real results by encouraging games and activities such as:

  • Keep count of how many times your kids turn off the lights in unoccupied rooms, and reward them after they reach a certain number each week.
  • Ask your children to track down all the incandescent lights in the house, and replace them with efficient bulbs together.
  • Use a Kill-A-Watt electricity usage monitor with your kids to identify which appliance or electronic in the house is the biggest energy hog. If you decide it’s time to replace it, shop for a new one with an Energy Star label together.

Check out the U.S. Department of Energy’s site for other games, tips, and facts.

Americans Don’t Know Jack About Saving Energy

TAGGED WITH  • • • • • • •

In this illuminating post by Grist, we learn through a recent survey by The Earth Institute at Columbia University that Americans really don’t know jack about saving energy.

The largest group, nearly 20 percent, cited turning off lights as the best approach—an action that affects energy budgets relatively little. Very few cited buying decisions that experts say would cut U.S. energy consumption dramatically, such as more efficient cars (cited by only 2.8 percent), more efficient appliances (cited by 3.2 percent) or weatherizing homes (cited by 2.1 percent).

About 2.8 percent of those responding said they could save energy by sleeping or relaxing more, compared with 2.1 percent who said they could do so by insulating their homes (can you guess which is actually more effective?).

Jonathan Hiskes of Grist asserts:

The theme of the confusion was that participants tended to name steps that involved doing less or using less of things — turning off lights, turning down thermostats — rather than solutions that allow them to get the same amount of light and heat through less energy (via insulation and LED bulbs). That gets at a key difference between conservation and efficiency. The first means using less; the second means getting the same results through more intelligent use of resources. Both have a place, but it’s a problem if people understand all of efficiency as “sacrifice.” A home retrofit that cuts $500 off your heating bills for the year isn’t a sacrifice — it’s a financial and environmental win.

Home energy fixes for under $100

Here are some easy and effective home energy fixes you can do around the house for $2 to $90:

  • Light switch and outlet sealers: under $5
    Two of the most frequently overlooked sources of air leakage in a home are light switches and outlets. Dodge those drafts by sealing up any switches and outlets where you can feel a draft on your hand.
  • Hot water heater pipe insulation: $2 per foot
    Use this cost-efficient fix as a quick way to reduce wasted energy on water heating. Insulating just the first 6 feet of pipe from your water heater will cost $12 and will save you over $5 a year on water heating while reducing CO2 emissions by more than 55 pounds. We typically recommend insulating the first 10 feet of pipe.
  • Monitor your meter: $20
    Purchase a Kill A Watt electricity monitor and plug in your appliances and electronics to find out which ones are the biggest energy culprits. Use this to inform your future upgrade decisions or see how much energy you can save with easy adjustments like turning down your refrigerator’s temperature.
  • Smart powerstrips: $20-90
    Cut back on phantom power by plugging electronics into smart powerstrips, such as the one by Wattstopper which turns devices on and off based on occupancy and uses a motion detector to manage energy use. Our recommended smart strip is Belkin’s Conserve.
  • Faucet aerator: $2
    These handy products are one of the least expensive ways to increase your water efficiency by mixing air into the water stream. When installed, each aerator will save 500-2,000 gallons of water a year.
  • Chimney balloon damper: $35-50
    The fireplace is a common area for heat loss in your home, as most dampers don’t work well and many older homes don’t have them. Inflatable balloon dampers fit in most chimneys to keep heated air in, and you can remove them whenever you want.

Got a Light?

Lighting accounts for 10% of all electricity consumed in the United States. Over half of that electricity is used in business and manufacturing.

Flicking a light switch is a simple motion. You do it dozens of times a day without thinking. It’s time to give it some thought. According to the World Resources Institute, the production of energy for lighting accounts for 10% of all the emissions of carbon dioxide, the main greenhouse gas. From 5% to 10% of your residential energy bill goes to paying for lighting. So it’s important to conserve energy by lighting right.

Energy Facts

  • Are “long-life” incandescent bulbs better for the environment? No. They’re actually less efficient than the regular ones, and can easily cost more in extra energy than they save on replacement bulbs.
  • It’s a trick: “Energy-saving” incandescent bulbs usually save energy simply because they put out less light than their regular counterparts. Check out the “lumens” rating on the package for the amount of light emitted.
  • Believe it or not: Dust on a light bulb or dirt on a glass fixture can reduce the light it gives off and make it seem that you need a brighter, higher-wattage light.
  • Even the paint color you choose can affect your energy use. The more light the walls reflect, the greater the chance that the light can be “recycled” by striking the wall, bouncing off, and still illuminating the room. A lighter wall can lead to a 25% energy reduction.
  • Opening curtains during the day will save lighting energy. Direct sunlight is 100 times brighter than the light from a strong reading lamp.
  • It used to be a good idea to leave fluorescent lights on if you were just going to be out of the room for a few minutes. But new fluorescents last longer even when switched on and off frequently.

Simple Ways to Save Energy

  • When you leave a room, turn off the lights. People commonly think it takes more energy to turn a light back on than it does to leave it on. But that’s not true.
  • Use only as much wattage as you need. Why waste energy with extra light? If you think you can get away with a lower-wattage bulb, try it out and see if it still seems bright enough.
  • Dust the bulbs and get the dead moths out of the fixture before you try a higher-watt bulb.
  • Use fewer bulbs in multi-bulb fixtures. Most people don’t realize that one strong bulb is more efficient than several weaker ones. For example: A single 100-watt bulb uses the same amount of energy as four 25-watt bulbs, but gives off about twice as much light. And it uses less energy than two 60-watt bulbs, but yields approximately the same light. Note: for safety’s sake, put a burned-out bulb in any empty sockets.

Save Energy with Light Switches

  • If any lights in your house are frequently left on when they shouldn’t be – in the garage or basement, for instance – you can install a timer to shut them off automatically. The timer plugs into the wall and the lamp plugs into the timer – simple!
  • Light timers are available at most hardware stores. If you’re a competent do-it-yourselfer, you can install them easily.
  • You can install dimmer switches wherever you need bright light only occasionally. If it’s an energy-saving dimmer switch (check it out when you buy it), you’ll have the option of using less energy on lighting at other times.
