What you get

The RICHFLAME RF45D-WC 33-Inch Electric Fireplace Insert is an electric insert with a 750-watt heater, which works out to about 2,559 BTU per hour (3.412 BTU per watt).

Its 750 watts means 6.2 amps on a household outlet and 0.8 kWh for each hour on high. The fuel cost calculator turns that into your hourly cost.

The maker says it heats up to 400 square feet; as with any 120-volt heater, read that as supplemental heat for one room.

Like most electric fireplaces the flame effect can run with the heater off, using far less power.

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 8.8 in (D) x 35 in (W) x 27 in (H), a shipping or unit weight of 55.7 lb and metal construction.
