imo, if you need space heating, a home-built thermosyphoning air heater
(a single layer of clear polycarbonate plastic over a darkened south wall
with an air gap and vent holes (which might be partially opened windows)
through the wall at the top and the bottom) and some thermal mass near
the ceiling (with a large heater) would have a better payback. 

the air heater might cost $2/ft^2 and return $1/ft^2 per year.
