The Liberty NexGen-Fyre™ is a big, beautiful stove that’s big on heat! Representing the largest model in our wood stove lineup, this powerhouse heater is an excellent choice for large homes and grand spaces.The Liberty NexGen-Fyre features a massive viewing area and a 3.65 cubic foot firebox that can hold logs up to 24 inches long!

This model features our advanced NexGen-Fyre™ technology. With NexGen-Fyre™, primary and secondary combustion are harnessed to create the ultimate blended combustion system that produces beautiful, balanced fires with double the BTU range, up to 50% greater heat output, and longer burn times than any other non-catalytic technology.

We dare you to compare! The Liberty NexGen-Fyre™ is 2020 EPA-Certified using the new EPA CORD WOOD protocol, rather than the CRIB WOOD protocol that most other manufacturers test to. By testing with CORD WOOD, you get a true real world measurement of how well the appliance will burn and perform in your home.
