How to choose
Read ECO and Energy Save modes
An ECO mode adjusts heat output by room temperature instead of running at full power all the time. The DREO, BREEZOME, and ZAFRO have ECO modes, and the COMFORT ZONE has an Energy Save setting while the BLACK+DECKER has an E-Save function. Compare how each mode works before you pick, since the names differ across brands.
Compare thermostats and timers
A thermostat holds a set temperature by cycling heat, while a timer sets how long the heater runs. The DREO sets from 41 to 95 degrees with a 12-hour timer, the BREEZOME has a 24-hour timer, and the ZAFRO sets from 41 to 95 degrees with a 24-hour timer. The BLACK+DECKER uses 5 preset levels from 60 to 80 degrees.
Check coverage and noise
Coverage is the maker's own figure for the space a unit serves, so compare it with your room before comparing watts. The DREO and the BREEZOME are rated for up to 200 sq ft by the maker, and the COMFORT ZONE is rated for up to 150 sq ft by the maker. For noise, the DREO runs at 34 dB, the ZAFRO runs at 34 dB or lower, and the BREEZOME runs at 40 dB.
