The Best Energy Efficient Space Heaters Tested in 2023

Flexibility is a great feature in a space heater, and the Heat Storm infrared space heater has it since it can be mounted on a wall or sat on a surface. This unit has 1,500 watts of heating power, so we tested it in the same 156-square-foot room. Since it boasts smart capabilities, we downloaded the Smart Life app and synched the heater with our Wi-Fi and smartphone. From there, we could see the room's existing temperature and turn the space heater on.

It took just 18 minutes for the Heat Storm to increase the temperature in the room by 5 degrees Fahrenheit. We found it to be pretty quiet, emitting a soft hum from its fan, but it wasn't an annoying noise.

This model can be hung on a wall, or a pair of two included plastic feet can be attached to the bottom to make it suitable for use on a table or floor. We found the plastic feet simple to connect, and they kept the heater level and stable. The unit also has tip-over protection for safety.

Unfortunately, we weren't big fans of the mounting setup. The mounting holes on the backside are 13.75 inches apart, which is too short a distance to mount to wall studs, which are 16 inches apart. Only one screw can be inserted in a stud, while the other must be inserted in drywall with an anchor bolt. The Heat Storm only weighs 9 pounds, so it's probably OK to mount it to drywall, but we would have preferred to mount it to two studs for extra stability.

In addition to being Wi-Fi capable, the Heat Storm comes with a remote, and a timer is accessible from the app or the remote. The app also allowed us to set a programming schedule for the heater. We appreciated being able to adjust the temperature from a touch screen on the front of the heater, and overall, we enjoyed the versatility of the unit.
