How to lower the cost of running an electric baseboard heater

Baseboard heaters are wall-mounted resistance heaters wired into a 240V circuit. Like space heaters, they convert electricity to heat at about 100%, and size determines cost: roughly 250 watts per linear foot. A home heated entirely by baseboards may have several units per room, so multiply by the number of units running. Enter the hours per day the heater is actually on — line-voltage thermostats cycle them on and off to hold the set temperature.

  • Install programmable line-voltage thermostats to lower temperatures when rooms are empty.
  • Keep furniture and curtains at least 6 inches away so heat can circulate.
  • Heating a whole home with baseboards? A ductless mini-split heat pump can cut heating costs by half or more.
  • Winters in New Hampshire are long, so heating appliances often run more hours here than the national default — adjust the hours above to match your home.
