DREO 25 Inch Electric Space Heater for Indoor Use, Large Room, Thermostat

Why it's worth it

This 25-inch tower oscillates across 70 degrees and rates as low as 25 decibels, which matters the moment your camera turns on. A dedicated thermal sensor holds your set temperature to within a degree, so you won't be reaching down to fiddle with it every hour.

Noise is the whole reason this one wins. Dreo rates its airflow design as low as 25 decibels, quieter than most refrigerators. Published reviews of Dreo's tower line consistently place it among the quieter options, and owner feedback echoes that. A heater you can't hear is a heater you'll actually leave running through a meeting. Louder units make you choose between being warm and being audible, and you'll pick audible every time.

The 70-degree oscillation covers a claimed 100 to 270 square feet, which is more room than most home offices have. Point it toward the middle of the room rather than at your chair. Warm air then circulates instead of blasting one shin while your other foot stays cold. If your office is one of those long converted bedrooms, that sweep is what keeps the far end from feeling like a different climate.

What to know

• –It's 25 inches tall and takes up floor space, so it isn't the heater for a cramped desk nook
• –The listing doesn't state app or voice control, so if you want to preheat the office from bed, this isn't the one
