Found that this electric heater: Dayton G73 (actually manufactured by
Marley Products as their UH5xx series) works quite well. Have a 30amp
circuit available? This is plenty for a 13'x24' well-insulated shop in
the Chicago area.


Glad to hear that. I'm in WI not far from Chicago, with a 20x20
uninsulated, unattached garashop that I'm planning to weatherize this
winter. I bought a Farenheat 240V which looks like it's pretty much the
same thing as the Dayton and got it installed yesterday. When the doors
were closed it did a really good job for that 45 degree rainy/windy day. It
went from damp and chilly to nice and comfortable in about twenty minutes.
Near as I can figure, that unit costs me about fifty cents an hour to run.

I know I won't be able to keep the shop above freezing all winter but at
least it'll be comfortable while I insulate, put up slatwall, cover the
rafters, and all that stuff I probably should have done this summer but
made sawdust instead. :-)

My shop is a dedicated 13x24 area in a detached 36x24 garage. Fully
insulated, thermopane windows in the shop area, etc. Concrete slab.

Installed the Dayton in February and set it to keep the shop between
50-55 degrees. If I'm going to work out there I go in when I get home
from the office and crank it. By the time I can change into work
clothes, I can work in shirtsleeves even if the temperature is below
freezing.

As for the cost? I used to use a Redi-heater and Kero-Sun heater when I
worked out there. Priced K-1 lately?g No smell, and I've not yet had
a heart attack looking at the electrical costs since we're total
electric out here anyway.
