A gas furnace is the king of providing toasty warm air for your home during a chilly Chattanooga winter season. Gas furnaces are powered by natural gas or propane.
A furnace in a very basic sense consists of a fan motor, a flame and a heat exchanger. When your indoor air registers as too cool, the flame ignites, and heats the heat exchanger (which is a metal, grid-type object). The fan motor pulls air from the home via the return air duct(s) and forces the cool air through the heated heat exchanger.
An Annual Fuel Utilization Efficiency (AFUE) is used to measure the ability of a furnace to convert fossil fuel to actual heat energy. This rating is shown as a percentage. That means a furnace rated at 95% AFUE is able to convert all but five percent of gas into heat energy!
New furnaces are able to have high AFUE ratings (up to 98.5% with the Carrier Infinity furnace). Things that affect efficiency are fully modulating flames that adjust in micro-increments, variable speed fan motors (which are also whisper quiet), and condensing technology that captures heat energy lost in older furnaces.
A Gas Furnace is an ideal way to heat your home during a Chattanooga winter season. However, gas furnaces are not always as efficient as an electric heat pump at mild winter temperatures. Hybrid heating is pairing a gas furnace with an electric heat pump. In the winter, the furnace and heat pump will switch based on the outside temperature and the cost of energy.
Hybrid heating can really save money in rural areas where natural gas is not available, and gas heating is done via propane. For more information, call your best choice for Chattanooga heating and air conditioning services! We’re ready to enhance the quality of your indoor comfort control.
