Best pellet stoves: EPA-certified pellet stoves compared (2026)

The only listed pellet stove here that needs no electricity: pellets feed by gravity and the stove drafts naturally, so an outage does not stop it. US Stove rates it at up to 40,000 BTUs for 2,000 square feet with a 60 lb hopper, and EPA lists it at 0.8 g/hr. You light it with a propane torch and set it by air intakes rather than a thermostat.

Best for A pellet stove that keeps working in a power outage

• Runs with no electricity
• 0.8 g/hr on EPA's list
• Small clearances to rear wall per manual

• Manual lighting with a torch
• No thermostat or auto-feed control

Who shouldn't buy it: Don't buy it if you want a thermostat and remote you can set and forget.

ComfortBilt rates the HP22 at up to 41,000 BTUs for 2,800 square feet with a 55 lb hopper, a programmable thermostat and a remote. EPA's list shows the HP22 at 1 g/hr and 81% efficiency, the best listed among these pellet stoves, though the manual revision we read shows 1.54 g/hr and 73.3%, so check the label on the stove. It shuts down in a power outage, and the manual says it should not be the only source of heat in the home.
