What you get

The Comfort Glow CGWI1800 Wood Fireplace Insert is a wood insert that its maker says heats up to 1,200 square feet.

In EPA's terms this is a medium heater. If the space it will sit in is much smaller than 1,200 square feet, look at a smaller model so it can burn at a healthy rate; the calculator lists the closest fits.

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

Its listing names the EPA standard. New wood stoves must meet EPA's 2.0 grams-per-hour limit, in force since May 2020.

It needs no electricity to burn, so it keeps heating in a power cut (the blower stops without 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 in (D) x 44 in (W) x 31 in (H) and cast iron door, plate steel construction.

Warranty, per the listing: 2 year manufacturer defect only.

Questions about this model

How big an area does the Comfort Glow CGWI1800 Wood Fireplace Insert heat?
The maker says up to 1,200 square feet. Treat that as a ceiling for an open, insulated space and measure the area around the stove.
Does the Comfort Glow CGWI1800 Wood Fireplace Insert need electricity?
Not to burn. Its blower needs power, so it runs without the fan in an outage.
