What you get

The Comfortbilt HP42-Alpine 2,800 Sq Ft Pellet Stove is a pellet stove that its maker rates at 42,370 BTU per hour and says heats up to 2,800 square feet.

Makers rate heating area in their own conditions, so read 2,800 square feet as a ceiling; the size calculator lists the closest fits for your space.

Its hopper holds 120 lb; refills depend on the heat setting you run.

It runs on electricity as well as pellets: the auger, combustion fan and room blower all need power, so a power cut stops it. Outage options.

Also on the listing: overall dimensions of 30 in (D) x 30 in (W) x 46 in (H), a shipping or unit weight of 275 lb and alloy steel 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 HP42-Alpine 2,800 Sq Ft Pellet Stove 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 HP42-Alpine 2,800 Sq Ft Pellet Stove?
It holds 120 lb. Higher heat settings empty it faster.
