What you get

The Comfortbilt HP22i 2,800 Sq Ft Pellet Fireplace Insert is a pellet insert that its maker rates at 41,000 BTU per hour and says heats up to 2,800 square feet.

Treat the 2,800 square feet as the maker's best case for an open, reasonably insulated space, and check it against your room before choosing.

Its hopper holds 47 lb; refills depend on the heat setting you run.

Without household power its auger and fans stop; check whether the maker allows a battery backup. Read the outage guide.

As an insert it goes into an existing fireplace opening; the firebox has to take its body and the vent runs up the chimney as the manual specifies.

Also on the listing: overall dimensions of 18 in (D) x 19 in (W) x 25 in (H), a shipping or unit weight of 273 lb and metal 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.

Questions about this model

Does the Comfortbilt HP22i 2,800 Sq Ft Pellet Fireplace Insert work without power?
No, not on its own: the auger and fans need electricity. A battery backup the maker allows, or a generator, keeps it running.
How long does a hopper last in the Comfortbilt HP22i 2,800 Sq Ft Pellet Fireplace Insert?
It holds 47 lb. Higher heat settings empty it faster.

Bottom line

Pick it for homes without a masonry chimney.
