What you get
The PuraFlame EF45B-OGF 33-Inch Electric Fireplace Insert is an electric insert whose maker rates its heater at 4,600 BTU per hour.
The maker says it heats up to 400 square feet; as with any 120-volt heater, read that as supplemental heat for one room.
The listing states 3 flame settings, and like most electric fireplaces the flame can run with the heat off.
As an insert it slides into an existing fireplace opening; measure the opening width, height and depth against the body dimensions, and the face against the trim. How to measure.
No combustion means no venting, no gas line and no carbon monoxide, which is why they go into bedrooms and apartments.
Also on the listing: overall dimensions of 8.78 in (D) x 35.04 in (W) x 26.96 in (H), a shipping or unit weight of 25.9 kg and metal construction.
