What Does It Cost to Run a Space Heater in Maryland?
Running a space heater in Maryland costs about $38.54 a month — $468.88 a year — at the state's average rate of 21.41 ¢/kWh. That's roughly $67.89 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 (delivery, fixed charges, and utility fees already included; locally billed taxes vary by area).

Space Heater cost vs U.S. average
At the state average rate, a space heater in Maryland costs $5.58 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. For the wattage range, amps, and how that math works, see how many watts a space heater uses.
Most space heaters draw close to their rated wattage when actively heating, which makes them one of the more expensive household appliances to run. Maryland prices that energy at 21.41 ¢/kWh, against a 18.31 ¢/kWh national average.
Space Heater operating cost estimate in Maryland
| Time period | Energy use | Cost |
|---|---|---|
| Per hour | 1.50 kWh | $0.32 |
| Per day | 6.00 kWh | $1.28 |
| Per month | 180.0 kWh | $38.54 |
| Per year | 2190.0 kWh | $468.88 |
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.

Source & Method
Source: U.S. Energy Information Administration (EIA) Retail Sales of Electricity. Updated: July 2026. Estimates use the EIA all-in average residential rate — energy, delivery, fixed charges, and utility fees together, not just the electricity itself. Fees are inside the rate, not an extra on top; how your own bill splits fixed versus per-kWh charges varies by utility. For what's inside the all-in rate, see hidden electricity fees; for how rates and estimates are defined, see the methodology hub.
