How to choose
Match the ECO mode to your routine
An ECO mode lets the heater adjust its heat level to hold the temperature you set instead of running at full power all the time. The DREO Space Heater, the PELONIS tower and the WINHL tower each has an ECO mode. Pair it with a thermostat: the DREO sets from 41 to 95 degrees in 1-degree steps, and the WINHL remote sets temperature, modes and a 12-hour timer. Check the thermostat range and the timer length before you buy, since those two controls decide how much the heater runs.
Compare coverage and noise figures
Every pick here draws 1500 watts, so wattage will not separate them. Compare the coverage each maker gives and the stated noise level instead. The DREO Space Heater is rated for up to 200 sq ft by the maker and puts noise as low as 37.5 dB, while the Amazon Basics puts it at 43 dB and the PELONIS at 50 dB. Match the coverage figure to your room size and the decibel figure to how much sound you accept.
Place it and plug it in
Plug a space heater straight into a wall outlet and keep the cord out of walkways. The WINHL maker advises plugging directly into a wall outlet rated for 15A and avoiding extension cords and power strips. A tower with a carry handle, like the Lasko, moves between rooms more easily than a unit you carry by its body. Give the heater clear floor space and keep it where its oscillation can sweep the area you sit in.
FAQ
What makes a space heater energy efficient?
Look for an ECO mode and an adjustable thermostat. An ECO mode adjusts heat to hold your set temperature, and a thermostat cycles the heater instead of running it at full power all the time. The DREO, PELONIS and WINHL picks here have ECO modes.
Do these space heaters have timers?
The DREO and WINHL have 12-hour timers, the PELONIS has an 8-hour timer, and the Lasko timer sets from 1 to 8 hours. Use the timer to switch the heater off after a set time.
What noise levels do these space heaters list?
Noise figures here are 37.5 dB for the DREO, 43 dB for the Amazon Basics, and 50 dB for the PELONIS. Compare the decibel figure with how much sound you accept in a bedroom.
Can I control these heaters from across the room?
The DREO, Lasko, PELONIS and WINHL each come with a remote control. Use it to change settings without walking to the heater.
