We live in an apartment in RI with an electric heat pump, and the blowing heat from the ceiling vents is inconsistent (hot/cool), and dirty and unpleasant. I've seen ads for electric space heaters (one promoted by Paul Harvey, and one in the back of TOH - Hydrosil). I'm wondering if any of them will be effective in a 16x18' room, and a substitute for the lousy heat we have now. (I know replacing the heat pump would be a slight improvement, however it's the blowing hot air that is so disagreeable and a new heat pump wouldn't solve that. Of course, I'm concerned about the cost of electricity too, but since the heat pump is electric, it might be about the same for space heaters.
