What you get
The Innoflame X 19 23-Inch Electric Fireplace Insert is an electric insert with a 1,400-watt heater, which works out to about 4,777 BTU per hour (3.412 BTU per watt).
At 1,400 watts it uses about 1.4 kWh an hour on high and draws 11.7 amps at 120 volts; keep it on a circuit without other big loads. Price it at your electricity rate.
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 4 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.
Because nothing burns, there's no chimney, vent or carbon monoxide to plan for.
Also on the listing: overall dimensions of 5 in (D) x 24 in (W) x 19.8 in (H), a shipping or unit weight of 18.1 lb and metal, tempered glass construction.
Warranty, per the listing: 1 year manufacuturer.
