General contractor Tom Silva has been lending his expertise to viewers of the PBS show This Old House for over twenty years. He knows that in the drafty winter months, keeping a New England home warm can seem nearly impossible without spending a fortune on heating costs.  Here are Silva’s best home heating tips to maintain a warm, energy efficient house:

Heating Houses1. Block Cold Air:

Old houses are going to have air leaks: around your light fixtures; around your outlets; around your windows; around your foundation. Your mission: to fill as many of those holes as possible with insulation.

Tom Silva’s recommended weapon of choice: foam in a can. “It’s a magical instrument,” he says. “It sprays and expands, and you don’t have to worry about forming a vapor barrier because it is its own vapor barrier. Air can’t move through it.”

Consider a typical outside light. Installing it probably required cutting into your home’s insulation, creating holes that now admit cold air. Silva recommends taking out the light and injecting foam just behind the junction box to fill any void that may have been created.

2. Don’t Feed Your Warm Air to the Fireplace:

Those crackling flames need oxygen, and to feed that appetite, your fireplace pulls air from all parts of your house, including the very air your furnace has worked so hard to keep warm.

One solution, Silva says, is to install glass doors in front of the hearth and an outside vent into the firebox. “The fire will take the air from outside the chimney and feed the fire; the fire will heat up the glass; and the radiant heat will heat up the space,” he explains.

3. Take Care of Your Heating Systems:

If the only time you think about your furnace is when you adjust your thermostat, you may be paying for it. Silva recommends that you get heating units cleaned professionally once a year and change the furnace filters at least twice a year. “Take the filters out, and if you can’t see through them or they’re starting to get a little gray-looking, change them,” he explains.

Don’t overlook the duct work, either. According to the U.S. Department of Energy, 25 percent of the air traveling through a poorly installed system never arrives at its intended destination. If you find air leaks at the seams, duct putty offers a simple fix, Silva says, as does foil tape, both of which you can use to cover the holes.

4. Insulate Hot-Water Heater and Basement Water Pipes

It’s not just your hot-water heater that needs some love. Your basement water pipes need love, too, and insulating them will do the trick. “There are all kinds of insulation options out there, and it’s a great weekend project,” Silva notes. “I recommend insulating as far as you can go, because with every 10 feet of pipe, you lose two to five degrees. That mounts up.”

5.  Use Blow-in Insulation:

Not long after Silva purchased his 1865 Victorian, he made the decision, in the middle of one particularly cold winter, to insulate. He opted for the blow-in variety, a cellulose product created from recycled newspaper.

Primarily a two-person job, the work involves punching holes at the bottom and top of each stud bay and filling up the space with densely packed insulation. You can rent a blower, and you can purchase bags of insulation at large hardware stores. The difference insulation can make, Silva says, is astounding.

“It was five or six at night, and we started at one corner of my house in the living room, and I worked across the back of the house, which was the living room, dining room, and kitchen wall,” he recalls. “My wife was inside the house, and as we were blowing each bay of the wall, she could actually feel the difference.”

6. Accommodate for Old Windows

If you’re intent on sticking it out with your old single-pane windows, make sure the glazing is intact. If it’s cracked, repair it. And be sure your windows are locked. “I don’t know how many times I’ve gone into a place where the owner has complained about a draft, and I’ve gone and locked the windows,” Silva notes. “It can make a big difference.”

So can insulating the cavities of your windows. High fuel cost doesn’t mean that you have to retire a home’s old rope-and-pulley windows, Silva explains. Instead, take the interior window trim off and pack the cavity, as well as the top and bottom of the window, with strips of rigid foam insulation.

Next, fill any voids with expanding foam insulation. Finally, in place of the rope-and-pulley, attach a spring balancer where the pulley is and hook it onto the bottom of the window. The result: Old World windows, New Age efficiency.

    The easiest way to make your home more energy efficient is to seal any air leaks, and one that is often overlooked is the bathroom ventilation fan and exhaust vent. The back-draft flap these units come with do a very poor job of stopping leaks. To address this issue, I use a replacement insert fan from the Larson Fan Company (online). Their fans has a true damper built in, that does a great job in keeping warm air in during the winter and hot, humid air out in the summer. This product has reduced my annual energy bills by over ten percent. It saves the most when air conditioning is being used.
