Test your homes energy efficiency. You can perform a simple audit of your home’s energy use by following the guidelines at EnergyStar.gov. You can also have PG&E or a home inspector evaluate the home.
Turn down the heat. Save money on your heating billsby setting your thermostat to 55 degrees when you are away from home for more than 4 hours. Alter the setting manually, or for $80-$120, purchase a programmable thermostat for your heater.
Avoid drafts. Plug air leaks with caulk or weather stripping to limit heat loss in your home. Check for leaks by holding a lit candle near vents, doors, window frams and mail slots. If the flame changes direction, there’s a leak.
Water works. To save money, set your hot water heater heater at 120 degrees. Electric and gas units can be covered with an insulating jacket for about $20. The isulation can help cut heat losses by up to 45 percent.
