Electric vs Gas Heaters: What’s The Difference?

If you’re facing the winter season with an older or frequently malfunctioning furnace, you might be feeling the pressure. No one wants to get stuck in the middle of a cold front with no heat, and a furnace replacement might be your best option for reliable heating! But, where do you start? What heating system works best for your home — and your budget?

Tim’s Southern Air is here to help you through it all. One of the biggest decisions you’ll have to make is choosing between the types of furnaces: gas or electric furnaces. What’s the difference between these two systems? Keep reading to find out how furnaces work and weigh the pros and cons of electric vs gas furnaces.

How Do Furnaces Work?

The main understanding that most homeowners have about their heating systems applies to both electric and gas furnaces. When the temperature in your home falls below the number set on your thermostat, a sensor signals the furnace to turn on. Once the air is heated, it is pushed back into your home until the sensor is satisfied that the space has reached the desired temperature. How the furnaces actually heat the air is where the two systems start to differ.

Electric Furnaces

Just in case the name isn’t clear, the source of fuel that electric furnaces use is electricity! Your electric furnace will be connected to the electrical system in your home and contribute to your energy bill every month. When the sensor in your home is triggered, the furnace turns on and allows electricity to flow over metal coils inside the unit. Since electricity creates heat, the metal coils become hot. When air from your home passes over these coils, the heat is transferred to the air. The warm air is then pushed by fans back through the ductwork and into your home.

Gas Furnaces

Gas furnaces are powered by natural gas. This gas source usually comes from a propane storage tank outside the home or the natural gas lines running underground. When the furnace turns on, gas is pumped into the unit through a pipe. An ignitor creates a controlled flame or heats a metal plate. This causes the gas to burn, creating heat. The heat exchanger — a series of thin-walled metal tubes — separates the combustion area from the rest of the furnace. The metal of the heat exchanger heats up like the coils in an electric furnace. As air from your home passes over the heat exchanger, the heat is transferred to the air. The warm air is then blown through the ductwork back into your home.

Pros & Cons of Furnaces

Availability of electricity versus natural gas may make the decision for you. If you have access to both, you may need more help determining the best option. Besides the fuel source, gas and electric furnaces each have their own set of pros and cons that could influence which system you choose for your home.

Expense

Electric furnaces are usually going to be cheaper upfront to purchase. However, electricity is more expensive than gas. This means that operating your furnace will be much cheaper if you only have to pay for natural gas or even propane.

Lifespan

Electric furnaces are only expected to last around 20 years — and that’s with regular maintenance and care. In comparison, gas furnaces can last up to 30 years.

Efficiency

It takes more energy to heat air with electricity than it does with natural gas, but electricity wastes none of the fuel it uses. This makes electric furnaces more efficient systems overall.

Safety

In the process of burning natural gas, carbon monoxide is produced. While your furnace is designed to expel all CO out of your home, malfunctions with your unit can lead to CO leaks in the home. Electric furnaces still pose a small fire risk, but they don’t use gas so there’s no risk of CO poisoning.
