How to choose
Match the heater type to the spot
A tower suits a bedroom or office corner, while a personal heater suits a desk and a panel suits legs and feet under a desk. The FLANUR is a portable tower with a carry handle. The BLACK+DECKER is a small desk heater with a carry handle. The Amaze mounts on a wall. The WHISPERHEAT is an under-desk panel for legs and feet. The HotCalyto is an under-desk panel with a heated foot mat. Pick the form that matches where the heat needs to land.
Compare coverage and wattage
Wattage runs from 100 watts on the Amaze heater to 1500 watts on the FLANUR and BLACK+DECKER models. Coverage is a separate figure: the Amaze heater is rated for up to 350 sq ft by the maker. Compare the coverage figure against your room size, and compare wattage only among models that heat the same kind of space.
Timers and controls
Timers and controls differ more than wattage here. The FLANUR has a 12-hour timer and a remote. The HotCalyto has a 12-hour timer with a foot-activated switch and a digital display. The WHISPERHEAT has a 2 or 4 hour shutoff timer and 3 buttons. The BLACK+DECKER uses manual controls. Choose the control style you will actually reach for.
