How to choose
Heat settings and modes
Heat settings differ across this list: the DREO offers 600W, 900W and 1500W modes plus eco mode, the De'Longhi offers 3 heat settings, and the Amazon Basics and Sweetcrispy offer 3 settings or modes at 600W, 900W and 1500W. The Homeleader offers a single 700W output with a knob thermostat instead of multiple settings. Match the settings to the room, since a lower setting suits milder days and full power suits colder days.
Thermostats and timers
Thermostats differ in control style. The DREO uses a digital thermostat with a remote control. The De'Longhi uses ComfortTemp to maintain temperature and power levels. The Homeleader uses a single knob. Timers also differ: the DREO includes a 24-hour timer and the Sweetcrispy includes an on-off timer. Check the timer before you buy, since a timer lets the heater warm a room before you arrive.
Weight and moving
Weight and moving differ across this list: the De'Longhi weighs 23.2 lb, the DREO weighs 17.6 lb, the Amazon Basics weighs 15.4 lb and the Sweetcrispy weighs 13 lb. Check the weight before you buy, since a lighter heater moves more easily between rooms.
