Assumption: 1,500 W at a 60% duty cycle, 8 hours a day, 120 days a year — 864 kWh a year. 1,500 W is the ceiling for a 120 V plug-in heater, and nearly every model sold hits it on high. A thermostat changes how often it runs, not how hard. Use the calculator to swap in the numbers from your own model.

Cutting the number down

Heating one occupied room and letting the rest of the house sit cooler is the whole case for a space heater. Running one in every room costs more than central heat.
Ceramic, oil-filled and infrared heaters all convert essentially 100% of the electricity to heat. At the same wattage the running cost is identical, whatever the box claims.
The cheapest watt is the one you skip: closing the door to the room you are heating does more than any model upgrade.
