Hire a pro to inspect your furnace once a year. To save on the cost of natural gas, heaters should be kept in tiptop shape, in order to run more efficiently. Replace furnace filters monthly or as often as the manufacturer recommends. Clean registers, and as you do, check to make sure your furniture is far enough away from the registers not to trap any of the heat you're pumping out. Install a programmable thermostat. While you're away from home, your gas heater doesn't need to produce as much heat, so you can set the thermostat to a lower setting during work hours and back to your desired temperature about an hour before you arrive home. That will save gas, and you'll never notice the difference! Gas wall heaters not only will keep a room warm, but they're also space-savers that you can install between wall studs. (If you have electric heat, some models allow you to use propane for a backup; you just use a conversion kit.)
Open drapes and blinds to allow the sun to naturally warm your home during the day, and close them when the sun sets to keep out the cold. Buy rugs or install carpet; a covered floor creates heat retention. Cover your fireplace by installing glass doors. You can also install a heat-air exchange, which forces the warmed air back into the room instead of up the chimney. (Remember to close the fireplace damper when not in use, and make sure the seal on the damper fits well.)
Oh, so many ways to save on water heating
Lots of small adjustments can help you reduce your water heating. Turn back the dial on the thermostat, and you'll save money. Use the energy-saving switch on your dishwasher. Only operate dishwashers and washers when you have a full load. Spend a little money on a low-flow showerhead and you'll save big in the bathroom. Speaking of showers, you'll use less water if you take a shower instead of a bath. Also, be sure to repair leaks quickly. A small leak will cost you; just one dripping faucet wastes almost 300 gallons in a month.
Tips for other appliances
You really don't need to preheat an oven every time you bake something. Only preheat when it's required; the rest of the time, put your food in when it begins preheating, and utilize that heat. The cook time will expand, but your oven will be on for shorter periods, because you are using all the heat it provides. If your food is nearly finished, as well, you can turn off the oven and use the residual heat to finish the food.
Use smaller appliances when possible, such as a microwave, toaster oven or slow cooker. When you purchase Whirlpool appliances, for example, look for energy-saving models. There are many ways to save money and natural gas. Heater, appliance and weatherproofing energy-saving tips are provided by every utility company, and the sales associate at your favorite department store can direct you to energy-saving appliances. With a little effort, you can save a lot.
