How to choose
Quiet figures first
Only the DREO states a decibel figure: 34 dB. The QOWETU is a quiet small heater, the De'Longhi is a full room quiet heater, and the Honeywell is a quiet compact heater. The De'Longhi uses mica-thermic technology for silent operation. When a decibel figure exists, compare it with your room use.
ECO modes and thermostats
ECO modes adjust output to hold a set temperature instead of running at full power. The QOWETU, De'Longhi and DREO all have ECO modes: the QOWETU holds 41 to 95 degrees, the De'Longhi uses ECO PLUS, and the DREO sets 41 to 95 degrees in 1-degree steps. The Honeywell uses an adjustable thermostat with 65, 70, 75 and 80 degree settings instead. Match the control type to how much adjusting you want to do.
Coverage and timers
Coverage figures differ: the De'Longhi is rated for up to 300 sq ft by the maker, the DREO is rated for up to 250 sq ft by the maker, and the Honeywell is rated for up to 160 sq ft by the maker. For timers, the QOWETU and DREO have 12-hour timers, the De'Longhi has a 24-hour timer, and the Honeywell has 2, 4 and 8 hour auto-off options. Compare coverage with your room size and timers with your routine.
