Understanding the Role of Furnace Burner in Heating Systems
The furnace is the primary heat source in most American homes. The system uses ductwork to distribute heat throughout a home and can be fueled by natural gas, oil, or propane.
It’s popular because it’s a highly efficient heating system, especially since you can upgrade outdated models to reduce annual energy consumption.
How a furnace burner works
The furnace burner is the part of the furnace where fuel is burned and heat is generated. Regardless of the fuel type, air mixes with the fuel in the burner to make a combustible mix for burning.
That can only happen when the furnace gas valve receives a thermostat signal, another essential part of the furnace. This valve allows fuel to enter the burner in a controlled amount. At the same time, outside air is taken into the burner.
When ignited, the system uses a metal heat exchanger to heat room air. The warm air then travels via pipes and vents and spreads throughout the house.
The pre-mixer
Some furnaces come with a pre-mixer, located right before the burner, where gas and air pre-mixes at the proper ratio before getting sent into the burner. This allows for more efficient heating and may lower energy bills.
Types of furnace burners
Homeowners have a choice of several types of furnace burners.
Conversion burners. This type accepts a converter so that you can switch from oil to natural gas.
Upshot burners. Commonly found in older furnaces, these burners use natural draft for air and fuel flow.
Inshot burners. Present in modern high-efficiency furnaces, these burners use induced draft to ignite the fuel.
The benefits of an upgraded furnace
Upgrading the furnace has multiple benefits, not only for the homeowner but also for the planet.
Modern furnace burners:
Can reach an efficiency of 98.5%
Reduce energy bills
Lower pollution
Take up less space
Maintenance
It’s recommended to give the furnace an annual check-up to ensure there are no leaks and all the parts are working well. The best timing might be the fall, just before the start of the heating season.
The replacement schedule for furnace filters is every three months, which is also a good time for homeowners to examine the flame color as it can indicate if something is wrong with the burner. Blue with a yellow tip means that the burner is working as it should.
If the flame is green, red, or orange, make sure to contact a heating company and get someone to look at the furnace.
Bottom line
Investing in an upgrade of the heating system can result in long-term benefits for both the household and the planet. Oil and gas furnaces require little professional maintenance and heat a home without skyrocketing energy bills or overly high emissions.
