How to choose
Match wattage to the space
Wattage sets the heat output level: the QOWETU draws 1500 watts, the COMFORT ZONE draws 1000 watts, the Teioe draws 800 watts and the Performance Tool draws 250 watts. A higher wattage suits a larger area, while a lower wattage suits a desk or personal space. Compare the wattage figures in this list against the size of the area you want to warm.
Compare coverage and thermostats
Coverage is the maker's own figure for the area a heater is rated for: the maker lists 100 sq ft for both the Teioe and the COMFORT ZONE. A thermostat holds a set temperature by cycling the heater on and off, while plain heat settings only pick a power level. The QOWETU, Vornado and COMFORT ZONE have adjustable thermostats; the Vornado thermostat offers 7 settings and the QOWETU holds temperatures between 41°F and 95°F.
Place it for steady airflow
Give a heater clear floor or desk space and keep its cord out of walkways. A tabletop model like the COMFORT ZONE or the Performance Tool sits on a desk, while a floor model sits on the floor. Keep the area around the heater clear so warm air can move through the room, and use the remote or the controls to change settings without moving the heater.
