What the Boxer 24 heats

Without a published area, compare the output with the heat a house needs. Estimated loss on a 0°F night (from average-winter use):

Floor area	1970s house, Oregon	Pre-1950, North Dakota	Within 25,389 BTU/h?
1,000 sq ft	15,024	19,224	Both
1,500 sq ft	22,537	28,836	Median state only
2,000 sq ft	30,049	38,448	Neither
2,500 sq ft	37,561	48,061	Neither

These are estimates from average use, not a heat-loss calculation of a real house, and a stove heats the room it stands in first. The Boxer 24 runs from 8,474 to 25,389 BTU/h, a 3-to-1 range, which helps in mild weather when a big stove would otherwise be turned down and smoulder.

Wood it burns in a winter

With its published 78.7% efficiency and a 1,500 sq ft example house, heating 1,500 sq ft (built in the 1970s) on generic 20 million Btu cords takes about 2.8 cords in Oregon and 4.9 cords in North Dakota. The maker quotes run time up to 25 hours on Low per load.

The species that burn best in any stove are the dense hardwoods Utah State rates excellent overall: osage-orange (30.5), black locust (28.3), white oak (27.9), apple (27), bur oak (26.3) million Btu per cord. Burn them dry; see how to season firewood.

Emissions and EPA rules

At 0.74 g/h the Boxer 24 is 37% of the EPA's May 15, 2020 limit of 2 g/h and 30% of the 2.5 g/h limit for stoves certified on cord wood. The EPA rules guide explains the limits.
