And I cannot lie, this thing is the business. After doing some research earlier this year, we had our zero clearance fireplace removed and replaced with the RSF Onyx with both the internal blower and the external blower, from which we ran ductwork to the 3 bedrooms and located the thermostat in the master. It has only gotten down into the low 30s a few times, but so far it is keeping the main part of the house in the mid 70s and the bedrooms at 70, and the heat is still there at 6-7am the next day. The gas central heat rarely comes on anymore. I am delighted.
Finding data on the RSF units can be difficult, so I thought to add this post for future reference when someone else is searching.
