What Does It Cost to Run a Space Heater in Alaska?
Running a space heater in Alaska costs about $49.23 a month — $598.97 a year — at the state's average rate of 27.35 ¢/kWh. That's roughly $175.86 a year more than a household paying the national average pays for the exact same space heater. The estimate assumes a typical 1,500-watt space heater running 4 hours/day, at the all-in average rate (before separately billed taxes and fixed fees).

Space Heater cost vs U.S. average
At the state average rate, a space heater in Alaska costs $14.45 more a month than it would at the U.S. average rate.
How much electricity does a space heater use?
A space heater draws roughly 750-1,500 W; we use 1,500 watts running 4 hours/day. That comes to 6.00 kWh a day — 180.0 kWh a month, or 2190.0 kWh over a year — using kWh = watts × hours ÷ 1000.
Most space heaters draw close to their rated wattage when actively heating, which makes them one of the more expensive household appliances to run. Alaska prices that energy at 27.35 ¢/kWh, against a 19.32 ¢/kWh national average.
Space Heater operating cost estimate in Alaska
| Time period | Energy use | Cost |
|---|---|---|
| Per hour | 1.50 kWh | $0.41 |
| Per day | 6.00 kWh | $1.64 |
| Per month | 180.0 kWh | $49.23 |
| Per year | 2190.0 kWh | $598.97 |
These figures use the all-in average rate. Your actual bill can run higher when separately billed taxes, seasonal pricing, and fixed monthly fees apply.
What changes the cost the most?
Two things move this number: your state's rate, which you can't change, and how hard the appliance works, which you often can. For a space heater, that mostly comes down to thermostat cycling, room insulation, outdoor temperature.
