How to choose
Coverage for large rooms
Wattage will not separate these picks, since each one draws 1500 watts. Compare the coverage each maker gives instead: the Ateroll is rated for up to 300 sq ft by the maker, while the Lasko and the Honeywell are rated for up to 200 sq ft by the maker. Measure your room, then pick a heater whose maker coverage covers that floor area.
Thermostats and heat settings
A thermostat holds a set temperature by cycling heat on and off, while heat settings only pick a power level. For heat settings alone, the Lasko has 3 heat settings and 2 fan speeds, and the DREO has 3 heat settings and 3 fan settings.
Oscillation and placement
Oscillation spreads warm air across a wider area instead of aiming it at one spot. The Ateroll oscillates 75 degrees, the Lasko uses widespread oscillation, and the DREO adds 60-degree vertical and 90-degree horizontal oscillation with 12 ft/s airflow. Keep clear space around the heater, keep the cord out of walkways, and plug it straight into a wall outlet.
