Natural Gas FurnacesUsing natural gas home furnaces as part of a home heating system is a very advantageous way to go. This is because they are the most efficient and economical way to heat your home. And since it is a forced air heating system, 115 degree warm air will be pushed into your living space through ductwork in your home.
The natural gas home furnace of today can operate at efficiencies of up to 97% AFUE or Annual Fuel Utilization Efficiencies. This provides homeowners with a very efficient ratio of 96 cents per 1 dollar of heat that is actually dispersed into their home. You can see just how efficient and economical the natural gas furnaces are when you compare them with the minimum standard of U.S. furnaces, which is 78%. Furnaces of the past needed to use chimneys. But these days, the units are able to extract more heat from the gas they use. So you are therefore able to vent them out the sidewall of your house with plastic pipes. Also, pilot lights that were in place in older model natural gas furnaces were replaced by a spark ignition system that saves more energy. There are many configurations in which natural gas home furnaces come. They come in an upflow design that you would usually install in basements. It is used to only to heat one and two story homes. It works by creating warm air that ends up traveling out of the top of the unit and upward. There is also a downflow design. They are installed on the first floor of a home. This model forces heated air out of the bottom of the unit, where it is then pushed into the ductwork under the floor of the home. There are even horizontal models that are installed in crawl spaces or attics. They work by pulling cooler air through one end and then blowing heated air out of its other end. These furnaces are also capable of providing your entire home with hot water. This is because they can circulate heated water from the boiler through a coil, which is submerged in water filled tank. At this point, heat is given off from the water as it flows through a coil. That, in turn, will provide your home with hot water. Natural gas home furnaces also come equipped with features like central humidifier units, night setback thermostats and electronic air cleaners. All of these features are designed to make your life a little easier and more comfortable when using your natural gas home furnace. Ask your HVAC installer about the advantages of natural gas furnaces.
