Optimizing Electric Furnace Usage: Tips to Save on Bills

How Much Does It Cost To Run An Electric Furnace


As the temperature drops, the reliance on electric furnaces increases, posing concerns about rising utility bills. To demystify the cost implications, it’s crucial to delve into the intricacies of electricity rates, heating requirements, and the comparative expenses of electric and gas furnaces. Additionally, adopting energy-saving practices can help mitigate the financial impact of prolonged electric furnace use. In this article , we will be explaining the cost to run an electric furnace.

Calculating Electric Furnace Costs

Understanding the cost of running an electric furnace requires a grasp of electricity rates, heating requirements, and usage patterns. With an average electricity cost of $0.12 per kWh, a 1,000-square-foot home needing approximately 45,000 BTU (British Thermal Units) for comfort can be estimated as follows:

\[ \text{Daily Cost} = 13 \, \text{kWh} \times 7 \, \text{hours} \times \$0.12 \] \[ \text{Monthly Cost} = \text{Daily Cost} \times 30 \]

This calculation illustrates that running an electric furnace for seven hours daily can result in a monthly cost of around $330.

Electric vs. Gas Furnaces: Cost Considerations

When contemplating heating options, the choice between electric and gas furnaces significantly impacts the overall expenses. Gas heating is consistently more economical due to the lower operational costs associated with gas. Gas prices, averaging around $0.90 per Therm, offer a cost advantage over electricity. For a 45,000 BTU gas heater operating for seven hours daily, the daily cost is:

\[ \text{Daily Gas Heating Cost} = 0.45 \, \text{Therm} \times 7 \, \text{hours} \times \$0.90 \] \[ \text{Monthly Cost of Gas Heating} = \text{Daily Gas Heating Cost} \times 30 \]

This comparison demonstrates the cost-effectiveness of gas heating over electricity.

Why Is Electric Heat Expensive?

The expense of electric heat is primarily attributed to the unit cost of electricity per kWh. As electricity bills increase, so do heating costs. Additionally, electric furnaces generally have a slower heating process compared to gas furnaces, contributing to prolonged usage and higher bills.

Strategies to Reduce Electric Heating Bills

1. Examine and Repair Air Leaks:

Identifying and sealing air leaks in windows, walls, and other areas can prevent heat loss and reduce electricity bills.

2. Optimize Thermostat Settings:

Utilizing smart thermostats allows for efficient temperature control, optimizing heating schedules based on daily routines and external weather conditions.

3. Leverage Natural Light:

Harnessing natural sunlight not only warms the home but also enhances energy efficiency.

4. Close Unused Room Doors:

Closing doors to unused rooms prevents heat dissipation, enabling more targeted and efficient heating.

5. Use Space Heaters Selectively:

Employing space heaters in specific occupied areas instead of heating the entire home offers a more economical heating solution.

6. Layer Clothing:

Wearing warm clothing indoors reduces reliance on electric furnaces, contributing to energy savings.

7. Regularly Change Filters:

Routine filter changes in electric furnaces ensure optimal performance and energy efficiency.

Assessing Furnace Efficiency

Modern high-quality furnaces boast efficiency ratings of around 95%, meaning only 5% of heat is wasted. In contrast, older furnaces, particularly those manufactured 20-25 years ago, may exhibit efficiency ratings as low as 60%. Upgrading to a more efficient furnace can result in substantial energy savings.

Conclusion (Cost to Run An Electric Furnace)

Awareness of the costs associated with running an electric furnace is pivotal in adopting strategies to mitigate expenses. From optimizing heating practices to considering alternative fuel sources like gas, homeowners can navigate the winter months while keeping utility bills in check. Exploring furnace efficiency and embracing energy-saving habits ensures a balance between comfort and cost-effectiveness.
