RSF Onyx

A contemporary design heater

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