Basics Of Gas Furnaces
To understand how a gas furnace works, let me explain the basics of gas furnaces and the various components present in them.
There are two types of ignition systems: pilot light vs electronic ignition systems. In addition, gas furnaces come with several electrical components that have their own power needs.
Lastly, gas furnace capacity and electrical power needs have to be understood in order to provide true heating. In this article, we will provide you with all the information related to gas furnaces to help you navigate any issues and service needs.
How Gas Furnaces Work
Gas furnaces use combustion to create heat. This is then distributed via ducts. When the thermostat registers the pre-set temperature, burners ignite and gas is lit with an ignitor.
Hot combustion gases flow through a heat exchanger, releasing heat to warm air. This air is then spread throughout the house via the ductwork.
Gas furnaces can be highly efficient, yet maintenance and checkups are required for them to work properly. Features like programmable thermostats and zoning systems can increase their performance.
Gas furnaces are reliable and great at providing heat in cold weather. Modern gas furnaces have new technology and more efficient ratings, making them a favored option for homeowners. So, why bother with matches when you can have a pilot light or electronic ignition system for your gas furnace?
Pilot Light vs Electronic Ignition Systems
Gas furnaces use either a pilot light or an electronic ignition system to start the heating process.
Pilot lights are small flames that are always on, while electronic ignition uses a spark.
Let’s compare the two:
| Pilot Light | Electronic Ignition | |
| Efficiency | Less Efficient | More Efficient |
| Cost | Cheaper initial cost | Moderate to expensive upfront cost |
| Safety | Requires monitoring | Fewer risks of gas leaks |
Pilot lights are cheaper, but less efficient. Electronic ignitions have moderate-to-expensive upfront costs, yet they provide more safety. Plus, they have fewer risks of malfunctions.
Furnace efficiency ratings vary, yet electronic ignition systems perform better on average. A study by Energy Star showed that an efficient gas furnace saves about $94 per year, for every percent increase in its AFUE rating.
So why risk electrocution when you can just stick with good old-fashioned combustion?
