FAQs
Are infrared heaters more energy efficient than ceramic heaters?
Infrared heaters are often considered more efficient for specific tasks because they heat objects and people directly rather than just the air. This means the heat stays in the room longer, even in drafty areas, whereas ceramic heaters focus on heating the air which can escape more easily.
Can I leave an energy-efficient space heater on overnight?
While modern heaters like the ones on our list have tip-over and overheat protection, it is generally recommended to use a heater with a programmable timer or a precise thermostat (like the Dreo or Shark) if you plan to use it while sleeping. Always ensure there is a 3-foot clearance around the unit.
How much does it cost to run a 1500W space heater?
At average electricity rates, a 1500W heater costs roughly $0.20 to $0.30 per hour to run on high. However, using “ECO” modes or thermostats (like those in the Vornado or Dr. Infrared) can significantly reduce this cost by cycling the power down once the room is warm.
Does a space heater really save money on my heating bill?
Yes, if you use “zone heating.” By turning down your central furnace and only heating the room you are currently in with an efficient space heater, you can save 10-20% on your total heating costs.
What is the quietest energy efficient space heater?
In our testing, the Dreo Solaris Slim H3 is the quietest, operating at roughly 34dB. This is equivalent to a quiet whisper or a library environment, making it ideal for bedrooms.
