It offers a strong heat output ranging from 19,000 to 37,000 BTUs, which means it can warm a room effectively while running cleanly with over 99% fuel efficiency.

The logs are finished in painted alloy steel, which should be durable but may not have the ceramic or molded look of some high-end sets.
