I dislike the use of space heaters because the space<br>
is so big with so many exit points and high ceilings.<br>
Heat rises. Heat to warm one's knees rises to the<br>
ceiling and into the light wells and cools against the<br>
glass or drifts to the east wall and exits through the<br>
cracks of windows or cools against the glass.<br>
Thanks lots for the arithmetic. I don't want to<br>
pay money to heat glass.<br>
