What you get

The Innoflame PD20-20 21-Inch Electric Log Set is an electric log set with a 1,400-watt heater, which works out to about 4,777 BTU per hour (3.412 BTU per watt).

On a 120-volt outlet that draws about 11.7 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.

The listing states 4 flame settings, and like most electric fireplaces the flame can run with the heat off.

As a log set it sits in an open fireplace in place of a grate; plan the cord route to an outlet.

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 8.5 in (D) x 20.5 in (W) x 11.7 in (H), a shipping or unit weight of 11 lb and metal construction.

Warranty, per the listing: 1 year manufacuturer.
