My Harman P61A does the bulk of the heating for my 1920's farmhouse, but I do use electric radiator heaters in the upstairs bedrooms when it gets chilly. I've got minimal insulation and no ductwork upstairs for my oil furnace. Electric is a lot cheaper than oil in my area, so no big deal. I have one large, open downstairs room on the opposite side of the house that I can't seem to keep much above 60 when we are in the low single digits, and rather than turn on the furnace, I'd like to just get an electric space heater for that one room. Any suggestions? I've brought the radiator heaters down and tried them, but they don't seem to circulate heat well in open rooms. Thanks!
