Last fall I installed a 20k btu GloWarm ventless in my 22x30
insulated/drywalled garage and even on the lowest setting it has not dropped
below 50deg. I live in Michigan. It is nat gas and I ran 1/2" black pipe
to feed it. I've not had any condensation problems, but either open/close
the garage door or crack one of the garage doors frequently.
With a computer/internet and XM radio in the garage, I now spend more time
there than in the house!
Of course, YMMV.
Safety Fast!
