Best Use

• The most energy efficient way to use space heaters is to heat a room where you will be working, sleeping or showering or where there are children or the elderly. Keep the door closed, and turn the heater off when the room warms up or if you leave.
  
  

Types of Space Heaters

• Forced air heaters blow warm air into the room, and radiant heaters generate heat by emitting radiant energy. Forced air heaters tend to heat a room more quickly, and radiant heaters generate more heat close to the heater.
  
  

Match the Heater to the Purpose

• If you will be sitting in one area of a room for a few hours, such as in an office, it is more energy efficient to use a radiant heater because it does not waste energy heating the whole room. If you need to heat the whole room, or if you want to take the chill out quickly, forced air heaters are probably a better choice.
  
  

Energy-Saving Thermostats

• Some space heaters have thermostats that let them cycle on and off to keep the room at a constant temperature while using less energy.
  
  

Energy-Efficient Models

• The most efficient models of forced air heaters heat a liquid that stores the heat and allows the heater to cycle on less frequently.
