How to choose
Read coverage as the maker's figure
Every pick here draws 1500 watts, so wattage alone will not separate them. Compare the coverage each maker gives: 200-300 square feet for the Comfort Zone, 400 sq ft for the Dr. Infrared Heater, 350 sq ft for the RealSmart, 200-400 square feet for the LifeSmart and 300 sq ft for the Lifeplus. Treat these as the makers' own ratings and compare them against your room's floor area.
Thermostat versus heat settings
A thermostat lets a heater cycle to hold a set temperature, while plain heat settings only pick a power level. The Comfort Zone, the Dr. Infrared Heater, the RealSmart and the LifeSmart have adjustable thermostats. The RealSmart sets from 50 to 90 degrees, the Dr. Infrared Heater sets from 50 to 85 degrees, and the Lifeplus sets from 59 to 86 degrees. The RealSmart and the LifeSmart also have ECO modes.
Placement, controls and upkeep
Give any space heater clear floor space and plug it straight into a wall outlet. A cabinet heater on caster wheels, like the RealSmart, is easier to roll between rooms than to carry, while the LifeSmart has built-in carry handles. The LifeSmart has a lifetime washable filter, and the RealSmart includes a dust cover for seasonal storage. Keep the cord out of walkways, and use the remote or the top panel where the pick provides them.
