How to How Do Furnaces Work?

Posted by on in Resources

As one of the most understated inventions of the 20th century, the furnace has quietly added huge levels of efficiency and comfort to all of our lives. Many people have benefited from a furnace but do not even know how it works to regulate your entire home's temperature from a central location. Let's take a look at some of the basics of the furnace.

Forced Air Heating

All furnaces work on the principle that is known as "forced air heating." Furnaces actually place heat in the air that comes through it. After this air is heated, fans will blow it through ductwork into your home through events. For heating and cooling, your furnace will often share ducts with an air conditioner. This requires less work and space to heat and cool the home.

Two Major Furnace Types

There are two major types of furnaces – an electric furnace and a natural gas furnace. The electric furnace does not use a pilot light in order to start the process of heating. It is also powered by electricity rather than by gas. The ignition on an electric furnace will activate the heating elements, and conductive coils will heat air to be blown out through the vents. If you turn the temperature up, the more those heating elements will work to heat the air in the furnace.

The natural gas furnace is the older of the two major types of furnaces. This is the furnace that you may have seen your grandfather light with a pilot. The natural gas furnace consists of burners in series that work inside of the combustion chamber. The burners create heat, then put it through an exchanger where that heat is then given to the air.
