Heat the room you live in.
Slide to the size of the open space around your hearth. Every stove and fireplace whose maker says it covers that space appears, closest fit first, because a heater far too big for its room burns low, smoky and wasteful.

Picks and matchups
Every list says how it's ordered
EPA puts new wood stoves at 2.0 grams of smoke an hour or less; older uncertified stoves put out 15 to 30. Dry wood and a stove sized to the room close most of that gap.

How Flueency compares heaters
Maker figures, one chart, plain arithmetic
The maker's own figures
Heating area, heat output, flue size, log length, hopper size and venting come from each model's listing. A figure that isn't stated is marked as not stated, never filled in.
Sized to the room
EPA's advice is to size a stove to the space it heats. The room check lists heaters rated to cover your space, closest fit first, so you don't overbuy.
Install and safety up front
Venting, chimney and gas requirements sit with each heater for your installer to confirm; safety guidance cites EPA, NFPA and CPSC. How we compare heaters.
