1. Fuel Source: Electric furnaces use electricity as their primary energy source, while gas furnaces use natural gas or propane. Check the fuel line or connection to determine the furnace's fuel type.
2. Venting: Electric furnaces do not require a vent or flue to exhaust combustion gases because they do not produce them. Instead, they have an exhaust fan that circulates warm air throughout the house. Gas furnaces, on the other hand, require a vent or chimney to expel the combustion gases.
3. Appearance: Electric furnaces typically have a more streamlined and compact appearance compared to gas furnaces. Gas furnaces often have a larger cabinet to accommodate the burner, combustion chamber, and heat exchanger.
4. Controls: Electric furnaces usually have a digital thermostat or control panel that allows you to set the temperature and fan speed. Gas furnaces, on the other hand, may have a mechanical thermostat or a combination of knobs and switches to control the temperature and fan settings.
5. Noise: Electric furnaces are generally quieter than gas furnaces because they do not have a burner or pilot light that produces combustion noise.
6. Energy Efficiency: Electric furnaces tend to be more energy-efficient than gas furnaces, especially in regions with higher electricity rates. However, this may vary depending on the specific furnace models and energy costs in your area.
