Protect Yourself From Higher Energy Costs This Winter

Count on it — this winter, energy prices are going up. Pacific Gas & Electric has already announced that natural gas bills for homeowners soon could increase by as much as 50 percent because of the escalating wholesale cost of natural gas. As a result, the utility says the January gas bill for an average Northern California home may jump from $50 to $75 a month.

Because of the higher cost of petroleum, prices are also going up for propane and fuel oil as well. And while electricity rates are still frozen by State law for most Californians, San Diego residents have already experienced a jump in their electricity rates.

So, despite forecasts of a normal winter, heating costs in most of the state will consume an increasingly larger portion of a household's energy budget. That's why it's more important than ever to check your home now to insure that your heating dollars aren't being wasted.

As winter approaches, use this checklist of simple ways to make your home more comfortable and keep those escalating energy bills at bay.

Check for leaks

Weatherstripping and caulking is probably the least expensive, simplest, most effective way to cut down on energy waste in the winter. Improperly sealed homes can waste 10 to 15 percent of the homeowner's heating dollars. Take these steps:

Check around doors and windows for leak and drafts. Add weather-stripping, and caulk any holes you see that allow heat to escape. Make sure doors seal properly.

If your windows leak really badly, consider replacing them with newer, more efficient ones. Keep in mind, however, that replacing windows can be expensive —it would take you quite awhile to recover your costs from the energy savings alone. But new windows also provide other benefits, such as improved appearance and comfort.

Every duct, wire or pipe that penetrates the wall or ceiling or floor has the potential to waste energy. Plumbing vents can be especially bad, since they begin below the floor and go all the way through the roof. Seal them all with caulking or weather-stripping.

Electric wall plugs and switches can allow cold air in. Purchase simple-to-install, pre-cut foam gaskets that fit behind the switch place and effectively prevent leaks.

Don't forget to close the damper on your fireplace. Of course the damper needs to be open if a fire is burning; but if the damper is open when you're not using the fireplace, your chimney functions as a large open window that draws warm air out of the room and creates a draft. Close that damper —it's an effective energy-saving tip that costs you nothing!

Examine your house's heating ducts for leaks. Think of your ductwork as huge hoses, bringing hot air instead of water into your house. Mostly out of sight, ducts can leak for years without you knowing it. They can become torn or crushed and flattened. Old duct tape —the worse thing to use to seal ductwork, by the way— will dry up and fall away over time, allowing junctions and splices to open, spilling heated air into your attic or under the house. It's wasteful. According to field research performed by the California Energy Commission, you can save roughly 10 percent of your heating bill by preventing leaky ducts.

Check your insulation

Insulate your attic. In an older home, that can be the most cost-efficient way to cut home heating costs. Before energy efficiency standards, homes were often built with little or no insulation. As a result, large amounts of heat can be lost through walls, floors and —since heat rises— especially ceilings.

How much insulation should you install? Typical framed homes now being built in California's Central Valley must meet insulation requirements of R-38 insulation in ceilings, and R-19 for walls and floors.

Check your heating system

Get a routine maintenance and inspection of your heating system each autumn to make sure it is in good working order.

Replace your heater's air filter monthly. You heating system will work less hard, use less energy and last longer as a result. Most homeowners can replace filters and do such simple tasks as cleaning and removing dust from vents or along baseboard heaters.

If your heating system is old, you might consider updating it. A pre-1977 gas furnace is probably 50 percent to 60 percent efficient today. That means only half of the fuel used by the furnace actually reaches your home as heat. Modern gas furnaces, on the other hand, achieve efficiency ratings as high as 97 percent. By replacing an old heating system with one of the most efficient models, you can cut your natural gas use nearly in half!

If you rely on electricity to heat your home, heat pumps offer the most efficiency. A heat pump can cut your electricity use for heating by as much as 30 to 40 percent.

Use your setback thermostat. California houses built today must have them —if you have an older home, consider installing one. A setback thermostat allows you to automatically turn down the heat when you're away at work or when you're sleeping at night, and then boost the temperature to a comfortable level when you need it. Remember —it takes less energy to warm a cool home than to maintain a warm temperature all day long. Properly using your setback thermostat could cut your heating costs from 20 to 75 percent.

Reverse the switch on your ceiling fans so they blow upward, toward the ceiling. Ceiling fans are a great idea in the summer, when air blowing downward can improve circulation and make a room feel four degree cooler.

A cooling draft is a poor idea when it's cold, however. By reversing the fan's direction, the blades move air upward in the winter. This is especially valuable in high ceiling rooms, where heat that naturally rises is forced back down into the room.

And, while you're at the store...

With shorter days, you'll be using electric lights more often. Buy a few of those odd-looking compact fluorescent light bulbs to replace the incandescent bulbs you've used for years. Compact fluorescent cost more to begin with, but they use one-quarter the energy and last as much as 15 times as long as incandescent do. Put them in locations where you have the light on often, and you'll recoup the up-front expense more quickly. It's another way to help take the sting out of higher energy bills.
