How to choose
Match coverage to the room
Coverage is the maker's own figure, so compare it with your room's floor area before you buy. The Mountman is rated for up to 450 sq ft by the maker, and the KEGIAN is rated for up to 350 sq ft by the maker. Measure the room first, then pick a coverage figure that covers it.
Thermostat control and heat modes
A thermostat holds a set temperature by cycling the heater, while plain heat settings only pick a power level. The DREO thermostat sets from 41 to 95 degrees in 1-degree steps, and the Mountman ECO mode adjusts within 41 to 95 degrees. The KEGIAN has an adjustable thermostat with ECO mode. All three have a remote and a timer: the Mountman and the KEGIAN have a 24-hour timer, and the DREO has a 12-hour timer. Pick degree control when you want a steady temperature rather than a fixed power level.
Noise, oscillation and moving it
Noise is stated in decibels, so compare the stated figure with the room where you use a heater. The Mountman lists noise of 30 dB or less, the DREO lists noise as low as 34 dB, and the KEGIAN lists noise at 30 dB. Oscillation spreads warm air across a room: the Mountman and the KEGIAN offer 120-degree oscillation. The DREO spreads warmth with 70-degree wide-angle heating. A remote helps change settings without walking to the heater. Place a heater on a flat floor with clear space around it, and keep cords out of walkways.
