How to choose
Match coverage to your room
Wattage alone will not separate these picks, since the DREO, TANGKULA and ARLIME all draw 1500 watts while the COSTWAY draws 700 watts. The useful number is the coverage each maker gives: 250 sq ft for the DREO and 215 sq ft for the TANGKULA. Compare that figure with your room's floor area before you choose.
Thermostat versus heat settings
A thermostat lets the heater hold a set temperature, while plain heat settings only pick a power level. The DREO sets from 41 to 95 degrees in 1-degree increments, the ARLIME sets from 40 to 95 degrees, and the COSTWAY uses a thermostat knob that sets from 32 to 194 degrees. The TANGKULA has 3 heat settings at 600W, 900W and 1500W with an adjustable thermostat.
Controls, timers and moving it
If you want to adjust heat without getting up, the DREO and the ARLIME include remotes, and both have 24-hour timers. The TANGKULA has four caster wheels for rolling it between rooms. The COSTWAY has a handle. Give any oil filled radiator clear floor space and keep its cord out of walkways.
