How to choose
Thermostat range and heat settings
A thermostat holds a set temperature by cycling the heater on and off, while a heat setting only picks a power level. The hykolity thermostat sets from 41°F to 95°F with 3 heat settings at 1500W, 900W and 600W. The COSTWAY uses a thermostat knob that adjusts from 32℉ to 194℉, the G-Ocean thermostat sets from 60°F to 90°F with 3 heat settings, and the ARLIME has an adjustable thermostat with 3 heat settings. Match the range to the room: a wider range gives more room at both ends.
Coverage ratings from the maker
Coverage is the maker's own figure, so compare it against the floor area of the room. The G-Ocean is rated for up to 162 sq ft by the maker, and the ARLIME is rated for up to 250 sq ft by the maker. Wattage does not tell the same story on its own: the hykolity, G-Ocean and ARLIME models each draw 1500 watts, while the COSTWAY draws 700 watts. A higher maker rating suits a bigger room, while a smaller rating suits a single bedroom or home office.
Moving it and storing the cord
Oil-filled radiators are heavy once filled, so casters and handles matter more than they look. The COSTWAY has a handle for moving it between rooms. Roll the heater to its spot, keep the cord out of walkways, and wind the cord onto its storage rack when the heater is put away.
