^^^ thats what I did. Mine isnt even insulated and it can get pretty toasty. Sure its a bit cold on the concrete especially near the overhead door, but its very manageable to heat quickly and easily. If its 20-30 out itll get up to 80 (on the unit) but if its in the single digits its hard to get it up to 65. Still comfortable enough to work, or throw darts, ect.
