@jessamyn the pellet stove in my great room plus a ceiling fan and a circulator fan keep my first floor zone comfortable and even gets up to the second floor if i position the circulator correctly at the bottom of the stairs. if my (24 year old… ) boiler goes, we’ll be looking at something higher efficiency for the baseboard heat and the hot water. being able to isolate rooms would be ideal (my wife works upstairs, has an electric heater for her office, no need to head the whole floor all day)
