When it hits hardest

winter peak

Baseboard heating is notoriously expensive in cold climates; Nov-Mar usage dominates.

Ways to cut the cost

  • 1

    Install a programmable line-voltage thermostat per room

    Reduces runtime 20-30%; eliminates over-heating while away

  • 2

    Seal drafts, weatherstrip doors, insulate outlets before winter

    Baseboard cost is ~50% envelope-driven; sealing cuts 15-20%

  • 3

    Set bedrooms 5°F lower overnight

    Saves 5-10% on winter bills
