How Do Gas Furnaces Work?

Gas furnaces are standard in the Greater Toronto Area due to their long lifespan, high efficiency, and low operational costs. If you’re interested in learning more about gas furnaces, this article focuses on how gas furnaces work and the benefits they bring to homes in Vaughan, Ontario. 

How Do Gas Furnaces Work – Heating Cycle

For you to know how the gas furnace functions, it is mandatory that you understand what the heating cycle entails. The gas source is connected to your furnace by use of a pipe from the outside entering your place. 

For the LPG units, you will need a storage tank outdoors as opposed to the natural gas furnaces that have underground connections with a gas pipe. In case you own the LPG unit, the gas will enter the furnace from the outside storage tank. 

If you won the natural gas furnace, then natural gas is supplied through the underground gas pipes, so as to light the burners present in the furnace.

At the furnace’s heat exchanger, cold air around your house undergoes heating. The air is warmed by burning gases present in your furnace. Combustion exhaust from your furnace must be piped out by use of your home’s exhaust pipe or rather through your vents. 

Warm air coming from your furnace is then distributed evenly to the various regions at your place by use of a blower, depending on the location, where the thermostats present in your place have been detected to be in need of heat. 

When the warm air is being distributed to all the different regions at your place, you will notice that the internal temperature increases gradually. Cold air is then redirected to your furnace by use of the return ducts. 

If the temperature setting is achieved, the thermostat will be in a good position to detect and switches the natural gas valve off in order to avoid the distribution of heated air.

Gas Furnaces Components

As of now, you are already aware of how do gas furnaces work. It is time to know the different gas furnace components and how each of them works in order to ensure the distribution of heated air at your place.

  • Burners

These are the small outlets present in your furnace where the gas emits from and is usually ignited into controlled even flames.

  •  Control board

This is a circuit board present in your furnace, that is meant to interpret differently electrical signals coming from the outside and inside of your furnace. It sends various signals as a response mechanism, these various things that include switching the blower fan or rather the burners on and opening your gas valve when your thermostat begs for heat.

  • Thermostat

This is a type of electronic device of which controls and measures indoor temperature thus regulating the heating cycle of your furnace in accordance with the point you set. You should be aware that the thermostat present at your place should be remotely located and also hard-wired to your furnace.

  • Blower fan

This is an electric motor and fan present in your furnace, which directs the heated air from the furnace at your place to different regions or rather rooms in accordance with heat demands.

  •  Flame detector

This is a component in your furnace that is meant to avoid the gas from dangerously building up in case the igniter doesn’t function. If there isn’t any heat detected in your system then the flame detectors must shut the gas flow off.

  • Igniter 

This component in your furnace is meant to light the gas coming from the burners. The igniters present in the furnace tend to function in a manner that a spark is created or rather an extremely hot platform is produced that ensures the gas passing by is ignited.

  • Heat exchanger

This is one of the largest components in your furnace and is made up of metal tunes that have thin walls of which separate the air getting in your place by use of the blower fan and the combustion operation. Cold air is then heated at the furnace’s heat exchanger and is finally distributed throughout your place evenly.

  •  Air filters

This is a membrane present in the furnace that keeps debris and dust from contaminating the heated air.

  • Plenums

In terms of how to do gas furnaces work, the plenums present ensures that the heated air is distributed to the air ducts. The return-air plenums tend to transport air from your rooms back to your furnace for heating purposes.

  • Gas valve

  this furnace component regulated the gas pressure in your furnace from a tank in case you are using the LPG furnace or the gas supply pipes.

  • Transformer 

This furnace component ensures that electricity is supplied to your furnace and also ensures that the required and correct voltage is achieved.

Furnace Safety and Maintenance

As of now, you are already aware of how to do gas furnaces work and the different components present in the furnace. You should be able to equip yourself with some safety precautions and regular maintenance tips. 

You should keep flammable items away from your furnace. You shot schedule regular maintenance and cleaning calls with your certified HVAC professional. You should also regularly replace or rather clean the filters at least after every two months or so. 

You should also not forget to outfit your place with a carbon monoxide detector and ensure that you test it every now and then. As of now, you should be able to enjoy the benefits of the gas furnace, which will provide you and your family with extra warmth especially during the winter season.
