Important considerations


  • Energy efficiency - Space Heaters are often more energy efficient than heating an entire room, as they can be directed to warm a specific area.
  • Safety - Most models have built-in safety features, such as tip-over shutoff, overheat protection, and automatic shutoff, that help to ensure your home is safe when using a space heater.
  • Portability - Space Heaters are designed to be lightweight and portable, making them easy to move around the home or office.
  • Cost savings - Space Heaters are often more cost-effective than central heating systems, as they require much less energy to operate.
  • Noise level - Space Heaters produce very little noise, so you won't have to worry about distracting noise when using one.


  • Costs: Space heaters can often be expensive to purchase and maintain, particularly when compared to traditional heating systems.
  • Fire Hazard: Space heaters may present an increased risk of fires if they are not properly used and maintained.
  • Waste of Energy: Space heaters may be inefficient at heating large areas, leading to wasted energy and higher utility bills.
  • Air Quality: Space heaters can reduce air quality by drying out the air in the room, creating dust particles and making it harder to breathe.
  • Portability: Space heaters usually require a power outlet to operate and, as such, cannot easily be moved from room to room.
  • Safety Concerns: Space heaters can pose a safety risk if not used properly, as they may overheat and cause burns or fires.

Common questions

  1. What type of Space Heater should I buy?
    This depends on the space you need to heat and your personal preferences. Electric space heaters tend to heat up quickly, and come in both portable and wall-mounted versions. Gas space heaters are larger, but provide more heat in a shorter amount of time. Radiant space heaters are good for spot heating in a limited area. Forced-air space heaters distribute heat more evenly throughout the space.
  2. What safety features should I look for?
    Look for features such as overheating protection, tip-over shutoff, and automatic shutoff timers. If the heater has a cord, look for a cord cover to prevent tripping. Make sure the space heater you purchase has the Underwriters Laboratories (UL) certification.
  3. Do space heaters use a lot of electricity?
    Yes, space heaters use a lot of electricity; however, the amount of electricity used depends on the size of the heater, type of fuel used, and the temperature settings. Generally, portable electric space heaters are more efficient than larger models.
  4. How do I know what size space heater I need?
    The size of the space heater you need depends on the area you are trying to heat. A larger space will require a larger heater, and a smaller space will require a smaller heater. Generally, you should measure the square footage of the space and use the manufacturer's size and BTU (British Thermal Units) recommendations for the size of the space.


A humorous fact about space heaters is that astronauts on the International Space Station (ISS) actually use space heaters to keep warm in the cold vacuum of space. According to NASA, the ISS is outfitted with more than 80 space heaters to keep the astronauts comfortable in the frigid temperatures. Source
