RSF Delta Fusion



Using technology exclusive to RSF Fireplaces, the Fusion has the first fully automatic fireplace air damper. Now, you have nothing to adjust other than the size of your wood load. Winner of the Hearth & Home 2016 Vesta Award, the Delta Fusion is the newest member of the RSF fireplace family.

Whether you are new to wood burning or have a lifetime of experience, you will appreciate how the Fusion automatically maintains a gorgeous, environmentally friendly fire while heating upwards of 3,000 square feet. Its innovative bimetallic air damper automatically regulates combustion, keeping the stove burning in a “sweet spot” which produces both minimal emissions and a visually striking fire. The low 1.3 grams per hour emissions is virtually unheard of in a heating appliance. The cleanest fires are achieved with lots of secondary combustion which is when the fire is most visually appealing.

This fireplace is certified for use with 8″ ICC Model EXCEL chimney only.
