How to choose
Wattage first, then heat settings
Wattage sets the heat ceiling here. The De'Longhi, Sweetcrispy and DREO run at 1500 watts, while the COSTWAY and Homeleader run at 700 watts. The De'Longhi and Sweetcrispy give 3 heat settings each, and the Sweetcrispy and DREO step through 600, 900 and 1500 watts. Match the wattage to your room size, then compare thermostats and shutoff features.
Thermostats and shutoff features
A thermostat holds the room at a set temperature, while shutoff features stop the heater on a fault. The Sweetcrispy, COSTWAY, Homeleader and DREO have adjustable thermostats, and the De'Longhi adds ComfortTemp control. Tip-over shutoff is on the Sweetcrispy, COSTWAY and DREO, and overheat protection is on the De'Longhi, Sweetcrispy, COSTWAY and Homeleader. Check both features before you buy.
Moving and placing the heater
Moving the heater matters in a small room. The De'Longhi has a handle. The Sweetcrispy has 4 casters and a carry handle. The COSTWAY and Homeleader have handles for moving rooms. Plug the heater straight into a wall outlet, as the Sweetcrispy maker also advises, and keep the cord out of walkways.
