How to choose
Compare ECO modes and thermostat control
An ECO mode changes how a heater holds a temperature. Instead of running at full output, ECO mode adjusts power to maintain the temperature you set. A thermostat does the related job of cutting output once the room reaches the setting. The NEWBULIG heater pairs a thermostat with ECO mode, the Ateroll heater uses ECO mode with a thermostat from 41 to 95°F, and the AEOCKY heater pairs an AI thermostat with ECO mode.
Match rated coverage to the room
Coverage is the maker's own figure for how large a space a heater is rated for, not a promise about how fast a room warms. The GiveBest heater is rated for up to 200 sq ft by the maker. The NEWBULIG heater suits spaces from 108 to 215 sq ft. If the room you plan to heat is near one of those figures, that heater's rating matches the need. Compare each heater on modes, controls and weight as well as rated coverage.
Check timers, remotes and weight
Timers and weight change daily use. The NEWBULIG heater has a 12-hour timer, the Ateroll heater has a timer from 0 to 8 hours, and the AEOCKY heater has a 24-hour timer. The NEWBULIG, Ateroll and AEOCKY heaters have remote controls. For moving the unit, the GiveBest heater weighs 3 lb, the Ateroll heater weighs 3.2 lb and the NEWBULIG heater weighs 4.12 lb.
