The RSF Comfort Advantage

Comfort is our specialty. We customize heat distribution from a wood fireplace throughout the home, including the basement. When the household temperature is tailored for a family at minimal cost and maximum efficiency, we call that the RSF Comfort Advantage.

Note: the central heating option is not available for the Pearl, the Focus 250 or Focus ST.
