How much space will it actually heat?

It is rated for about 220 sq ft, which is a small bedroom or office. Expect it to take the edge off a larger room rather than warm it fully.

Is it loud enough to bother sleep?

On low it is fairly quiet; on high the fan is clearly audible. Light sleepers may want to run it before bed and switch to low overnight.

It adjusts output but is not precise. Many owners set it slightly higher than the target and let ECO mode handle the rest.

It has a tip-over switch, overheat protection and a flame-retardant housing, and it shuts off automatically if knocked over.

Yes. At 16 inches tall and about 6 inches wide it fits on a desk or nightstand, but keep clearance around the vents and cord.

It ships with a remote control. Check the box for the battery type, since small remotes often use a coin cell.
