Will be running a Harman SF-150 in the basement of my new home and some need some advice on getting the heat to the upstairs. The home was a one story ranch but the attic was converted into two small bedrooms and one small bathroom. Will putting registers in the floor be enough with the blower on the stove or should I try and fabricate a heat collector and duct it right to the first floor? My main goal is to totally elimate the oil furnace. The advertised living space of the home is 1175 square feet.
