What you get

The Costway 11033US-CYPF 18-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).

On a 120-volt outlet that draws about 6.2 amps, most of a standard 15-amp circuit, so other loads on the circuit can trip the breaker. Plug it straight into the wall as the manual directs.

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.

Electric fireplaces burn nothing, so they produce no carbon monoxide and need no vent, chimney or gas line.

Also on the listing: overall dimensions of 5.3 in (D) x 19.1 in (W) x 17.9 in (H), a shipping or unit weight of 10 lb and abs, tempered glass construction.
