How to choose
Read coverage as the maker's figure
Every pick here draws 1500 watts, so wattage alone will not separate them. The coverage figures the makers give are 300 sq ft for the COSTWAY and 250 square feet for the ARLIME, each rated by its maker. Compare the maker figure against your room size before you choose.
Thermostat versus heat settings
A thermostat lets the heater cycle to hold a set temperature, while plain heat settings only pick a power level. All four picks have adjustable thermostats and 3 heat settings at 600 watts, 900 watts, and 1500 watts. The COSTWAY sets from 40°F to 95°F in 1°F increments, the hykolity sets from 41°F to 95°F, and the Dumos sets from -5 to 60°C, so compare the temperature range against your room needs.
Placement and cords
Give any oil-filled heater clear floor space, and roll it on its casters rather than carrying it. Plug the heater straight into a wall outlet rather than an extension cord, as the Dumos maker directs, and keep the cord in its storage rack or hidden storage when the heater is not in use.
