Is the Honeywell HCE840B good for a bedroom?

Yes for a medium bedroom, especially with the thermostat and timer. The fan noise is the main drawback for light sleepers.

How much space does it heat?

It is built for medium rooms and zone heating. Warmth is strongest close to the unit and fades in large or open spaces.

It draws 12.5 A at 1500 W, so plug it into a dedicated circuit and avoid sharing it with other high-draw appliances.

Yes. Both are adjustable, so you can set a target temperature and a shut-off time.

It has overheat protection, a tip-over switch, and automatic shut-off. Still, never leave any portable heater unattended for long periods.

It heats faster and is more directional, but a radiator-style heater is quieter and holds warmth longer after shut-off.
