You can winterize your home without spending a lot of money, according to renovation expert Bob Vila. Clean your gutters and flush your water heater to make it run more efficiently; you can also lower its settings to slash utility consumption or switch to environomentally-friendly solar heat. If you can’t afford new windows, get an inexpensive roll of weatherstripping tape and press it into place to cut drafts, and caulk gaps around windows, doors and siding. And finally, get a programmable thermostat to avoid heating your home when you’re not there.
