An electric heater is 100% efficient, as it can generate the same amount of heat that it consumes in electricity. Electric heaters are the most popular type of space heater because it is easy to find an electrical source and the cost of fuel is rising.
An electric heater only costs pennies per hour to use. They are relatively inexpensive to purchase and there are many types. You can find a space heater to fit your needs.

There are some things to keep in mind when using an electric space heater. The problems with space heaters arise when basic safety precautions are not followed. Make sure the heater is UL listed. Heaters are not so expensive that you need to take the risk of using an unsafe appliance. Keep flammable items, such as curtains and clothes at least three feet away from the heater.
Space heaters can be power hogs. Do not overload your home's circuits. If possible, do not plug anything else into the outlet where the heater is connected and use a good surge protector. If you must use an extension cord, use a 12 or 14 gauge cord.
