What you get

The US Stove US1800E 1,200 Sq Ft Wood Fireplace Insert is a wood insert that its maker rates at 69,000 BTU per hour and says heats up to 1,200 square feet.

That puts it in the medium class EPA describes: a small house or a medium-sized energy-efficient house. Read the area as a ceiling for an open, insulated space; the size calculator compares it with your room.

The firebox takes logs up to 18 in, so cut or order wood a little shorter than that.

A wood stove keeps working when the grid goes down, though its blower needs power.

As an insert it fits into a masonry fireplace; the firebox opening has to take its body, and the chimney needs a liner sized to its collar.

Also on the listing: overall dimensions of 20.2 in (D) x 27.53 in (W) x 22.33 in (H), a shipping or unit weight of 300 lb and cast iron construction.

The figures, from the maker

Each figure is the maker's or the listing's own, with its source marked. A figure the maker doesn't give is shown as not stated.
