*Square-feet heating capacities are approximations only. Actual performance may vary depending upon home design and insulation, ceiling heights, climate, condition and type of fuel used, appliance location, burn rate, accessories chosen, chimney installation and how the appliance is operated.

Steady State Rating: Since most homeowners use their fireplaces for an extended time Steady State measures how efficiently your fireplace converts fuel to heat once it is warmed up and running in a "Steady State".

AFUE rating is more typically used for furnaces that continually cycle on and off to maintain a constant temperature.
