How to choose
Read coverage as the maker's figure
Coverage is the maker's own rating, so compare it with the room you heat. The Comfort Zone is rated at 150 sq ft by the maker, and the Lutntc is rated at 200 sq ft by the maker. Wattage also differs: the Comfort Zone and the Lutntc draw 1500 watts, while the Pereysi and the Oprunsy draw 1000 watts.
Thermostat versus heat settings
A thermostat holds a set temperature by cycling heat, while plain heat settings only pick a power level. The Comfort Zone, the Lutntc and the Pereysi have adjustable thermostats. The KIDEE and the Oprunsy use heat settings and modes instead, so compare the control style with the room you heat.
Placement and controls
Give any space heater clear floor space and plug it straight into a wall outlet. Handles help move a heater between rooms: the Lutntc, the KIDEE and the Pereysi each have a carry handle. Knob control suits a quick change, while touch buttons and a digital display suit checking the temperature and mode.
