Electric baseboard heating costs an average of $400 per month for a 1,200-square-foot house. Your monthly cost can vary depending on factors such as regional climate, energy usage, and the efficiency of your system. Improving insulation and using zone heating can help manage operational expenses. Local electricity rates have a significant impact on costs, with some areas experiencing rates that are up to 50% higher than the national average. Older units are less efficient, resulting in higher monthly heating costs.
