3 Ways to Cut Your Electric Baseboard Heater Energy Bill

  • 🌱

    Vacuum the fins and element regularly — dust acts as insulation and reduces heat output, forcing longer run times.

  • 💡

    Install a line-voltage programmable thermostat to precisely control cycling instead of using the built-in dial.

  • Keep furniture and curtains at least 12 inches away from the unit to allow natural convection airflow.

Startup Surge Information

Baseboard heaters use resistance heating coils with no motor, so they draw a steady, predictable wattage with no surge.
