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: 576 sq ft for the Dr Infrared, 280 sq ft for the PELONIS, 270 sq ft for the DREO 25 Inch and 200 sq ft for the DREO Space Heater. These are the makers' own ratings, so treat them as a guide and compare them against your room's floor area.
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 Dr Infrared, both DREO models and the PELONIS have adjustable thermostats; the DREO pair and the PELONIS set in 1-degree steps. The Lasko uses 2 heat settings with a remote.
Placement and cords
Give any space heater clear floor space and plug it straight into a wall outlet rather than an extension cord, which the PELONIS listing also calls out. Keep the cord out of walkways. A cabinet heater on wheels, like the Dr Infrared, is easier to roll between rooms than to carry.
