How to choose
Thermostat types compared
Thermostat control differs across this list. The DREO uses a digital thermostat that sets from 41 to 95 degrees, with a remote control and a large LED display. The COSTWAY, Tangkula, and hykolity use knobs: the COSTWAY pairs its knob with 3 heat settings, the Tangkula pairs its knob with an eco mode, and the hykolity pairs its knob with 3 heating modes. Pick digital control for degree settings, or a knob for simple turns.
Wattage and coverage
Wattage sets the heat output, and coverage sets the area the maker rates. The DREO, the COSTWAY, and the hykolity run at 1500 watts, while the Tangkula runs at 700 watts. The DREO and the hykolity each heat up to 250 sq ft. Match wattage and rated coverage to the room you plan to heat.
Moving and placing it
All four heaters sit on the floor. The DREO has large wheels and handles. The COSTWAY has 4 casters and a front carry handle. The Tangkula has an easy-carry handle. The hykolity has caster wheels and carry handles. Place the heater on a flat floor with clear space around it, and keep the cord out of walkways.
