How much space will the Baboom 18 Inch heat?

At 1500W it is best treated as supplemental heat for a small room, roughly a bedroom or small living area. It will not carry a large open-plan space on its own.

Does the flame effect work without heat?

Most freestanding electric fireplaces of this type let you run flames alone, and the remote makes that easy. Check the flame-only setting on arrival before relying on it.

Can I plug it into a normal wall outlet?

Yes, it uses a standard plug, but at 1500W it pulls close to 12.5A. Avoid sharing the circuit with a space heater, microwave or hair dryer.

What is included in the box?

The fireplace unit and a remote control are the core items. Batteries for the remote and any mounting hardware are not confirmed in the listed specs.

How does it compare with a wall-mounted electric fireplace?

This one is freestanding, so it needs floor space but no installation. Wall-mounted units save floor space but require mounting and often hardwiring or a nearby outlet.
