What the Columns Mean

Low and high BTU/hr. The heat output measured at the lowest and highest burn rates in the certification test. This is the range to size a stove with. Some listings print the two values in reverse order; we’ve put the smaller one first.
HHV %. Overall efficiency as a weighted average of the test burn rates, on the higher heating value basis that EPA uses (40 CFR 60.534). It’s the strict number; a maker’s LHV figure for the same stove reads higher. See HHV vs LHV.
g/hr. Particulate (smoke) emissions in grams per hour, weighted across burn rates. The 2020 limit is 2.0 g/hr for crib wood and pellet tests and 2.5 g/hr for the cordwood test option (40 CFR 60.532).
Test fuel. 125 listings were tested on crib wood (a stack of dimensional lumber), 30 on cordwood and the rest on pellets. The same firebox can test differently on each, so compare like with like.
New. Listings EPA flags as recently added.

What Stands Out

151 of 265 room heaters list 75% HHV or better: 71 wood stoves and 80 pellet stoves. That was the threshold for the 25C tax credit, which ended for stoves placed in service after 2025.
Wood stove efficiency by type. Median 78% for catalytic stoves, 79% for hybrids and 71% for non-catalytic stoves. The best wood listing is the Blaze King 30.2 series at 83%. Pellet stoves have a median of 77%, from 51% to 86%.
One listing isn’t marked as meeting the 2020 standard: the Dielle FBX pellet line. Every other room heater on file is.
The highest tested output among room heaters is the SR-3.2 series from Stove Builder International at 83,857 BTU/hr. The median room heater tops out at about 31,000 BTU/hr.

Hydronic Heaters and Furnaces

Outdoor wood boilers (hydronic heaters) and wood-fired forced-air furnaces are certified under a different subpart, 40 CFR 60 subpart QQQQ, and report emissions in pounds per million BTU of heat output rather than grams per hour. The 2020 limits are 0.10 lb/MMBtu for hydronic heaters tested on crib wood (0.15 on cordwood) and 0.15 lb/MMBtu for forced-air furnaces (40 CFR 60.5474).
