Here is detailed information about What Are The Components Of An Electric Furnace? An electric furnace is made up of various components. Getting to know all of them isn’t a good idea, but getting a handle on a few of the more significant ones is. You’ll know what to look for if your electric heater ever breaks down or has any problems.

The more you know about your electric furnace’s components, the better off you will be. Having a rudimentary understanding of at minimum a few of the operating parts of your electric furnace is a good place to start.

What Are The Components Of An Electric Furnace?

An electric furnace’s heating element comprises several tightly coiled metal coils. They frequently reside in a block with two or three tiers of several coils stacked on top of one another. Electric relays begin the ignition process when your thermostat signals for heat, but not all of the coils heat at once.

Different coils are only allowed to heat up when a sequencer component is allowed. Electrifying the coils in a precise order permits the coils to heat in a pattern that creates enough heat without overloading your electrical panel.

If all the coils were heated at once, the power consumption would be too severe for your electrical system. The furnace’s fan switches on and blows the warmed air into your ductwork once the coils have heated the air around them to the appropriate temperature.

Components Of An Electric Furnace


Your electric furnace needs a transformer to get the power it needs from the grid. All of the electrical energy from one circuit can be transferred to another by using a transformer. What many people don’t realize is that the core of your electric furnace has more than one currency.

When the primary current passes through the secondary winding, it creates a magnetic field. If there is a load linked to your secondary, then the secondary’s winding will easily allow the flow of electric current. This signifies that the primary circuit’s electrical energy will be delivered to the load.


A sequencer is a device that controls the on/off status of the heating elements in an electric furnace. There’s no limit to how many people it can help. Due to its ability to reduce the electric current surge, a sequencer is required. You may experience this if your electrical equipment is activated in any way.

Getting your electrical equipment charged is as simple as plugging it in. Your unit could blow if all of its components are electrified at once, and this is why it’s so critical that you keep an eye on your fuses and breakers. Things can get out of hand quickly if this happens frequently, and it can add up to a significant financial burden.


In an electric furnace, a contactor serves as an intermediary between the furnace’s power supply and the heater’s heating element. Essentially, this indicates that your thermostat is a major factor. As a result, the reset button will be activated by the thermostat if it does not have a particularly high voltage.

When the thermostat determines that the desired temperature has been reached, the contractor will open the connection and switch off the heat. Without your contactor, your electric furnace won’t be able to perform much for you. A heating system is a must throughout the winter months to keep your house warm and cozy.

What Is The Function Of The Heating Element?

Several, tightly-wound metal coils make up the heat source in an electric furnace. It is common to see two or three layers of coils on top of each other in a block. Electric relays initiate the ignition process when your temperature calls for heat, but not all of the coils heat at once. A sequencer is used to control when different coils can be heated.

Electricity is drawn from your electrical panel if all of the coils are heated at once; this is why the coils are electrified in a certain sequence to avoid overheating your electrical panel. The furnace’s fan pumps warm air into your ducts once the coils have heated the air around them to the proper temperature.

Heating Element Issues

An electric furnace’s heating element can malfunction just like a gas furnace’s burner or heat exchanger. Tripping circuit breakers – as you might expect, an electric furnace can draw a substantial amount of electricity, necessitating the installation of an independent panel. There is either an issue with too much electricity or a defective breaker, both of which necessitate the attention of a trained professional.

In some cases, it’s necessary to replace a part because of a malfunctioning component. A defective sequencer can prevent your heating element from working, so you’ll need to get a new one if this is the case. If you want to get the most out of your electric heater, you should always get it serviced by a knowledgeable professional.

A Comparison Between Gas And Electric Furnace

Electric furnaces don’t produce carbon monoxide, which is a plus over conventional fuel types. The system’s lack of carbon monoxide stuff makes it more environmentally benign and easier to put in place. A flue isn’t needed to remove these pollutants from your home, making installation easier.

When you use an electric furnace, all of the electricity generated is used to heat your home. After combustion, a portion of the energy utilized to generate heat is expelled through the flue in gas-fired boilers. On the other hand, gas is less expensive than electricity on a per-kWh basis.

The cost of running an electric furnace is one of the main drawbacks of the appliance. In many places, electricity is more expensive than gas. In some regions, electric furnaces are used in conjunction with heat pumps to save more money than using electricity alone.

Electric Furnace Heating Elements

Every central electrical furnace in a home has two heating elements, depending on the stove size.


Here we end up all about What Are The Components Of An Electric Furnace? Or What Does An Electric Furnace Look Like? Electric furnaces are preferable to other furnace types in certain places and circumstances.

Electric furnaces are similar to gas furnaces in operation, with the exception that they generate heat through the use of electricity rather than gas. For example, instead of gas burners, an electric furnace uses electric heating elements.

Using an electric furnace is like blow-drying your hair. They use a heat exchanger to bring fresh air into the system. Electric heating components reheat the air in the heat exchanger once it has been placed there. The blower then pushes this heated air into your home’s ductwork, where it is distributed to the various rooms.

Frequently Asked Questions

Does a typical electric furnace have several key components?

Electric heating components, air filter control; cold air returns, air filter, blower, belt, motor, & ductwork are all components of an electric furnace.

What do you call the various components of a furnace?

Stoves, heat exchangers, compressors, and duct and exhaust systems are all components of your furnace’s control system. Combustion gases are expelled from your home through a flue pipe when you use your furnace to heat your home.

What about electric furnaces?

Electric furnaces include filters, just as any other furnace. For a furnace to function properly, it must have a filter. There’s a filter in the electric furnace’s blower section. Maintenance and filters are necessary even for electric furnaces so that they can keep you warm throughout the cold winter months.

In the majority of electric furnaces, how are the heating elements controlled?

A thermostat is used to control all types of electric resistance heating. While some devices employ low-voltage thermometers, most baseboard heaters use line-voltage thermostats (the thermostat directly controls the power supply to the heating unit) (To switch the unit on and off, the thermostat makes use of a relay).
