How To

Winterizing Your Home: Reduce Heat Loss & Energy Bills

By Nina Golgowski on

Basic insulation and sealing techniques can reduce your home's heating costs up to 20% according to the Environmental Protection Agency. With winter just weeks or days away, now's the perfect time to ensure your home will retain the most energy and heat possible to get your family through the season toasty and affordably. Here are a few inexpensive, simple and fun ways:

1. Update or add to your attic insulation:

Your attic is one of the biggest zones of energy loss, potentially losing up to 45% without proper insulation, according to the Department of Energy, which makes it the perfect place to get started.

While it most likely has some form of insulation in place, it's still a good idea to make sure whatever padding you do have is up to date with the current recommended insulation levels. Depending on when your house was built, the levels may have been much lower than those suggested today.

To stay further green conscious, newer products are available containing recycled and natural material. Cellulose, for example, an insulator scattered or blown, is the most family friendly composed of recycled paper.

While over time cellulose does settle, reducing its efficiency compared to fiberglass, it's known to provide greater insulation than its competitor.

If you do use fiberglass which offers exceptional durability, adding an extra layer across what you already have will also make a noticeable difference. Just make sure there are no air pockets between layers or that any of these extra are the kind with a paper backing on one side (this backing which lists its R value - the higher R value equals a higher heat retention - is a vapor barrier which could actually trap water between the layers rather than keep it out).
Make sure there's a minimum of 12 inches for it to do its job.

2. Reverse your ceiling fan

Most ceiling fans today have a feature that will reverse the fan's blades pushing heat that accumulates at the surface of your home downward. It's a simple measure, but one that could save up to 10% in heating costs. Just don't forget to make the switch again when the season warms up.

3. Find and seal a room's heat leaks

The average American home has heat leaks enough to amount to a nine-square-foot hole according to the EarthWorks Group. Finding them and sealing them is essential to keeping that energy in.

Once a leak is found, you can seal the source - a window, lighting fixture, outlet, etc. - using either a foam sealant or caulking ranging from about $4-7. These small leaks can add up to 5-30% of your lost energy a year, according to the DOE. 





4. Sealing window and door leaks

While replacing your current windows and doors with storm doors/windows can increase your energy efficiency by 45%, there are other minimal steps, just as good, if your budget isn't in the clear this season.

A simple door snake purchased or made at home will block out a gusty drafts as well as keep the warmth in. Better yet, installing rubber sliders, using (removable) gel weather strips, vinyl gaskets (nail on) or rubber/foam tape, will more surely guarantee protection from potential heat leaks.

An additional option is a window insulation kit. While applying the film across the glass is said to be mildly tricky by users, it's an inexpensive application ($6-14) which promotes up to 90% heat retention. Have no fear of cold winter windows again!

5. Insulate your pipes


If a pipe is warm to the touch, that heat should be wrapped. Purchasing foam padding, some which are pre-cut, to wrap around these pipes will help insulate costly heat already generated by your house for better savings and less wait while standing in the shower. Look for padding with the highest R-value for the greatest insulation.

6. Replace or clean your furnace filters

A dirty furnace filter will promptly restrict air flow requiring an increased amount of energy to push through. That's extra energy totally wasted.  If using a disposable filter it's recommended that you change the filter once a month during the heating season. Switching to a permanent filter however will not only prevent waste, but they clean better too! While a bit more expensive, Electostatic filters trap around 88% of debris with disposable fiberglass filters in comparison are said to trap only 10-40%.
