How to choose
Match thermostat range to the room
A thermostat holds a set temperature by cycling heat, while plain heat settings only pick a power level. The DREO thermostat sets from 41 to 95 degrees in 1-degree steps, the FNIOP ECO mode sets from 59 to 95 degrees in 1-degree steps, and the ZAFRO thermostat sets from 41 to 95 degrees. Compare the range against the temperatures you use most.
ECO mode and timers
ECO mode adjusts output to hold the set temperature instead of running at full power all the time. All three picks have an ECO mode, and the DREO and FNIOP each have a 12-hour timer while the ZAFRO has a 24-hour timer. Check the timer length against how long you want the heater to run.
Noise, size, and controls
Compare the stated noise figures before you buy. The DREO lists 34 dB, the FNIOP lists 35 dB, and the ZAFRO lists 34 dB or lower. The DREO and FNIOP include a remote. The ZAFRO has touch controls and an HD display.
