Energy efficient mechanicals in your home is the first step to reducing the amount of fuel you use. At Wyman Energy, we can get your old system running optimally and help you compare that cost versus replacing with new and cost effective equipment that can save you money in a few short years.
- Turn down the thermostat. “The rule of thumb is that you can save about 3% on your heating bill for every degree that you set back your thermostat” full time, says Bill Prindle, deputy director for the nonprofit American Council for an Energy-Efficient Economy (ACEEE). Turn down the thermostat 10 degrees when you go to work, and again when you go to bed — a total of 16 hours a day — and you can save about 14% on your heating bill, says Prindle.
- Use fans wisely. In just one hour, a hard-working bathroom or kitchen fan can expel a houseful of warm air, according to the Department of Energy. Turn them off as soon as they’ve done their job.
- Keep the fireplace damper closed. Heat rises, and an open damper is like a hole in the roof. Also, limit use of the fireplace, since fires actually suck heat from a room, says Harvey Sachs, director of ACEEE’s buildings program. Close off seldom-used rooms. And shut the vents inside.
- Turn down the water heater. Lowering the temperature of water in the water heater to 115-120 degrees reduces power use often without a noticeable difference to the user, says Prindle.
- Keep heating vents clear. Vents blocked by rugs and furniture prevent heated air from circulating efficiently.
- Use curtains. Opening curtains and shades on south-facing windows during the day allows solar radiation to warm a living space; closing all curtains at night helps retard the escape of that heat.
Web sites on the topic abound, but one of the best is run by the Department of Energy.
So you’ve put the easiest, and free, ideas to work. Now you can really make a dent in that heating bill with one cheap trip to a hardware store (Home Depot, for example, has all of the items below) and a few hours of work
Block that leak!
The small gaps surrounding windows, doors and other areas in the American house, taken together, are like a 9-square-foot hole in the wall, according to EarthWorks Group’s “30 Simple Energy Things You Can Do to Save the Earth.” Plugging them can save you up to 10% on that heating bill, and the materials will pay for themselves within a year, ACEEE says.
First, find the leaks: On a windy day, hold a lit incense stick to the most common drafty areas: chimney flashing, recessed lighting, sill plates, window and door frames, all ducts and flues and electrical outlets.
Buy door sweeps ($3-$10) to close spaces under exterior doors, and caulk ($2-$5 per roll, plus a $10 caulk gun) or tacky rope caulk to block those drafty spots around window frames. Apply weather-stripping ($3-$6 for up to 17 feet) to movable joints. Outlet gaskets ($10 for 10) can easily be installed in electrical outlets in a home’s outer walls, where cold air often enters.
Keep your ducts in a row
A home that uses ductwork to move heated air can lose up to 60% of that air before it reaches the vents if the ducts are poorly connected, not well insulated and travel through unheated spaces such as the attic or crawlspace, says the government. “If you are a halfway savvy do-it-yourselfer, and your ductwork and heating and air-conditioning equipment are in the attic, you can do an awful lot to fix your system, at low cost,” says Sachs.
First, look for obvious places in the attic, basement or in crawlspaces where ducts have become disconnected. Reconnect them, and fix places where pipes are pinched, which impedes flow of heated air to the house, says the Department of Energy’s Ryan.
Fix remaining gaps with tape, but don’t use traditional duct tape, which deteriorates; instead, use metal-backed tape ($6-$10 per roll) or aerosol sealant. Where possible, wrap the ducts’ exterior with special duct insulation ($8-$12 for 15 feet). Though the cost will be substantially more, it’s a good idea to get a professional to help insulate ducts when electrical wires or lighting fixtures are nearby.
- Swaddle water heater and pipes. Unless you’ve got a newer water heater that already has built-in insulation, covering your water heater with an insulated “jacket” ($17-$20) will keep costs down, especially if your heater is in an unheated place like a garage. Also, wrap water pipes ($1-$5 per 5-foot section) when possible, especially when they run through uninsulated areas.
- Winterize windows. If you can’t afford storm windows, put plastic film on those windows ($6 covers three windows) where a clear view isn’t crucial, which will curb drafts and keep windows from rattling.
- Buy a low-flow shower head. A water-efficient shower head (often less than $20) can use 25% to 50% less hot water, saving both on water and power bills, with little to no reduction in user satisfaction, says Prindle.
- Buy a smart thermostat. If you’re the kind of person who forgets to turn the temperature down at night and before work, but who doesn’t mind programming things like the TV remote control, a “smart” thermostat ($50-$100) can be set to change the temperature for you.
- Keep your furnace in shape. “It’s amazing how often a heating or air conditioning unit stops working because a $3 or $15 air filter is clogged,” says Sachs. Replace the air filter ($4-$16) according to manufacturer’s directions and your heating system will operate more efficiently. Oil-fired boilers should be cleaned and tuned annually, and gas systems, every two years($100-$125). By maintaining your heating unit, you can save between 3% and 10% on heating bills, says ACEEE.
- Look for other insulation opportunities. Some well-placed insulation, especially in the attic of older homes, can save a bundle ($7-$16, in rolls from 22-32 feet, depending on insulation value).
