About baseboard heater running costs

Electric baseboard heaters give roughly 250 W per foot of length. They are quiet but expensive to run all day.

Typical sizes: 500 W, 750 W, 1,000 W, 1,500 W, 2,000 W.

How to spend less: Lower the thermostat by 1 to 2 degrees and close doors to rooms you are not using.

What this estimate assumes

  • The appliance draws its full stated wattage the whole time it is on. Real units with a thermostat cycle off and cost less.
  • Wattage is the typical label value, not a measured value. Check the label on your own appliance.
  • The rate is an approximate residential average. Your bill may include fixed fees, tiers or time-of-use pricing. Edit the rate above.
  • A month is 30 days and a year is 365 days.
