How to choose
Read coverage as the maker's figure
Every pick here draws 1500 watts, so wattage alone will not separate them. The useful number is the coverage each maker gives: 280 sq ft for the PELONIS and 270 sq ft for the DREO. Compare the maker ratings against your room's floor area, and check each pick's own coverage figure before you buy.
Thermostat versus heat settings
A thermostat lets the heater cycle to hold a set temperature, while plain heat settings only pick a power level. The DREO sets from 41 to 95 degrees in 1-degree steps. The PELONIS sets from 40 to 95 degrees in 1-degree steps. The RealSmart sets from 50 to 90 degrees. The Lasko uses 2 heat settings with a remote. The Reekie uses a thermostat knob with a power level knob. Match the control type to how you heat the room.
Timers, oscillation, and moving
Timers and oscillation differ across these towers. The PELONIS has a 12-hour timer with 75-degree oscillation. The RealSmart has a 12-hour timer. The Lasko has an 8-hour timer with widespread oscillation. The DREO has 70-degree oscillation with a remote. The Reekie moves on 4 swivel caster wheels with a cord winder. Match the timer, the oscillation, and the moving parts to the room you heat most.
