Seal your home's drafts. Locating drafts, or openings in your home is easy. There are products such as handheld draft detectors, or you can use an age-old draft detector, a lit candle. Turn off your heater, make sure no windows are open, and walk around slowly looking for disturbances in the flame. This will locate where outside air is entering the home. Once you find these drafts, repair them by replacing weather stripping, using spray foam insulation or caulking.
