How to choose
Oil radiators versus other heaters
Only the ARLIME and the Tangkula are oil-filled here: both have 7 sealed fins with diathermic oil that never needs refilling. If you want oil heat, compare the ARLIME at 1500W with the Tangkula at 700W, and check heat settings before wattage alone.
Thermostats, timers and controls
The Vornado adjusts power and airflow on its own through auto climate control, and the Tangkula and the ARLIME use adjustable thermostats with energy-saving modes. Compare the control you will use daily, since a remote or app suits a wall-mounted heater.
Noise, weight and moving
Noise matters in bedrooms: the DREO lists 28 dB, and the Tangkula and the ARLIME list noise lower than 45 dB. Weight matters for moving: the Honeywell weighs 4.5 lb, the Vornado weighs 5.4 lb and the DREO weighs 6.1 lb. The ARLIME rolls on 4 casters. The Tangkula has a carry handle, so check how you will move the heater between rooms.
