How to choose
Choosing the best digital heater by thermostat
A thermostat holds a set temperature by cycling the heat, while plain heat settings only pick a power level. The DREO and the ZAFRO set from 41 to 95 degrees, and the DREO adjusts in 1-degree steps. The Oprunsy pairs its thermostat with ECO and natural wind modes. Match the control style to how closely you want the temperature held.
Compare noise ratings for bedrooms
Noise ratings separate these picks more than wattage does, since all three draw 1500 watts on high. The ZAFRO lists 34 dB, the DREO lists 37.5 dB, and the Oprunsy lists lower than 50 dB. If a bedroom heater runs while you sleep, put the decibel figure first and check it against the room where it will sit.
Timers and placement basics
The DREO has a 12-hour timer, while the ZAFRO and the Oprunsy have 24-hour timers. Set the timer for the hours you need heat, and place the heater with clear floor space around it. Plug it straight into a wall outlet, and keep the cord out of walkways.
