Weatherizing For Winter

Heating
Remember our Energy Star mantra: Set heater 2 degrees lower in winter - energy efficient setting is at 68 degrees, so try to go 2 degrees lower to 66 degrees.

If you don't already have a programmable thermostat, get one now. This ensures you will be heating or cooling hour house only when you are home and it is necessary.

Portable heaters can be a good option to warming one room where you spend a lot of time, rather than heating the whole house or a whole floor. Portable heaters operating @ 1500 watts can cost 20-25 cents an hour. The most energy efficient and safest portable heaters are radiant heaters with both a thermostat and timer; can be purchased at Target on Broadway..

At night turn thermostat down to 62 degrees or less. If still cold, sleep with a down comforter or electric blanket.

Change the air filter for your heater as frequently as monthly. Purchase filters with the maximum number of pleats; the more pleats the more efficient the filter.

Insulation
Attic insulation is one of the most effective ways to keep your house warm in winter; 40-60% of heat loss is through the attic/ceiling.

If your insulation is more than 15 years old, chances are it has settled and/or it doesn't meet today's standards. Current standards call for at least R-30 in the attic, R-13 in the walls, and R-19 in the floor. Don't insulate above R-38 in the attic or insulation won't breathe.

Rake and fluff old insulation if mashed down before adding new.

Cellulose and fiberglass are the most common form of attic insulation. Either is effective.

Even if you have poor insulation in your walls, it's still effective to add or beef up attic insulation.

Weather Stripping
Older homes have nooks and crannies where air escapes. Heat inside finds its way to the cold outside, minimizing the work your heater is doing.

Because up to 20% of the heat inside a typical house is lost through the windows, check the weather stripping and caulking around doors and windows.

If you can easily slide a piece of paper under your door while it is closed, this indicates a gap that's letting too much air in or out. Local hardware stores sell pre-made rubber strips for the underside of doors.

Foam switch plate backing for light and electric switches help seal pathways around this little air conduits. Local hardware stores sell packets of these foam insets for easy installation.

Fireplaces
Use a flash light to check inside your fireplace to make sure damper has a good seal. If not, contact a chimney sweep for help.

Close fireplace damper when not in use. This prevents warm air from escaping up the chimney.

HVAC Ducts
You can have the most efficient heating unit, but if ducts aren't sealed tight and run correctly, your heater won't be doing its job properly.

SMUD will come check your ducts for just $25. Call them at 1-888-742-7683.

Hot Water Heaters
Make sure your hot water heater is insulated. Newer models come already self-insulated. But if you have a model more than 5 years old, look for the manufacturer's phone number on the hot water heater to verify the appropriate insulation.

If you are considering purchasing a tankless hot water heater, make sure it has the capacity you need. Gas tankless hot water heaters are best; electric ones use too much electricity to be energy efficient.

Hot Tubs
Hot tub heaters use 5,000 - 6,000 watts. In winter, turn down the hot tub to 80 degrees or turn off completely when not in use. Newer models will reheat quickly; older ones not so much. Purchase a thermal blanket that lays on top of the water to hold heat in and a cover that fits snugly to insulate and keep heat from escaping.

Phantom Loads
We hear a lot about reducing phantom loads - electric currents being drawn from appliances not in active use. Here's the latest on this subject from SMUD.

It is not necessary to unplug appliances that do not have digital clocks or internal timers, such as toasters, blenders, portable heaters, when not in use.

But electronic appliances like computers, TVs with Tivos and DVRs should be turned off when not actively used. Tivos and DVRs can run $12-14 per month in electrical costs, not to mention the wasted energy.

Thinking of buying a plasma TV? Look for the Energy Star label to ensure energy efficiency. Plasma screens can generate a lot of heat, so look for one with a cooler screen.
