Using our online cost calculator, you'll see that a 1,400-watt space heater used an average of four hours a day will cost you about $17 a month to operate.
To make the most of a portable heater, follow these tips:
Use it in a small or enclosed space.
Place it the corner of the room.
Keep doors to the room shut to keep the heat in.
Turn it off when you leave the room.
No matter what kind of space heater you're using, it's important to keep safety top of mind. Ensure it won't tip over, use it on a level floor, keep blankets and fabric away, and never go to sleep with the heater on.
