Sometimes it makes sense to warm up just a small area like an office or bedroom rather than turn on your central heating system. Portable, or room, heaters can effectively and efficiently heat smaller areas of a home or business.
You’ll want to remember that space heaters, even though small, use a significant amount of electricity. With a typical 1500-watt unit, for instance, it will cost you about 16 cents per hour. That doesn’t sound like much, but if you leave a portable heater on for several hours a day or use multiple heaters, it adds up. Smart use of a space heater can save you money compared to using central heating, but being cautious about extended use is important.
Here are some tips on how to manage electricity costs if you use a space heater:
- Remember to turn it off when you leave the room.
- Select the right space heater for the situation. Check out our Space Heater Guide to identify what type of heater is best for you.
- Space heaters work best in smaller rooms that are closed off to the rest of your home. An open door will quickly reduce the effectiveness of the heater.
- If you’re using multiple space heaters for more than a few hours it may be more cost effective to use your central heating, which is the most efficient way to heat your entire house.
- Since space heaters use a lot of electricity, multiple heaters on the same circuit can trip a circuit breaker.
- The higher wattage of these units exceeds the capabilities of most extension cords, creating a fire hazard. Plug your space heater directly into an outlet.
The U.S. Department of Energy also provides some good tips on space heater safety and what to look for when making a purchase.
Meanwhile, putting on a sweater or sweatshirt instead of using that space heater could save you a dollar a day or more. For a little entertainment and a few tips, check out our video comparing three different types of space heaters.
