RSF Onyx 2 Built-In Wood Stoves

Our customers tell us that the Onyx 2 has the most colorful, dynamic flames they have ever seen, the kind of flames which are impossible to duplicate with gas. The Onyx 2 can provide enough heat for the average house, burn overnight, and look great, all at the same time. Patented RSF technology enables the Onyx 2 to burn so cleanly that it is EPA certified to the same standards as the best freestanding wood stoves.
