How to choose
Wattage will not separate these picks
Every pick here draws 1500 watts, so wattage alone will not separate them. The useful differences are heat levels and control type. The PELONIS, Sweetcrispy, and DREO give 3 heat levels, while the hykolity gives 3 heating modes and the De'Longhi gives a digital panel with an ECO Plus feature. Compare the level count and the control type with the heat you need each day.
Thermostats and heat levels
An adjustable thermostat holds a set temperature by cycling heat, while plain heat levels only pick a power level. All five picks have an adjustable thermostat. The PELONIS sets from 41 to 95 degrees in 1-degree steps, and the DREO sets from 41 to 95 degrees as well. The PELONIS, Sweetcrispy, and DREO use 600W, 900W, and 1500W levels, so a lower level uses less power on milder days.
Placement, cords, and moving heaters
Plug the heater straight into a wall outlet and keep the cord out of walkways. The hykolity moves on caster wheels with carry handles. The Sweetcrispy has 4 heavy-duty universal casters and a carry handle. The De'Longhi moves on Smart Snap wheels with front and rear handles. The PELONIS has a universal freewheel and handles. The DREO comes with a heater, a manual, and a guide, so keep the manual where you can find it.
