Thermostat Location

I've just installed a radiant tube heater against the back wall of my garage and am trying to figure out the best location for the thermostat.

The garage is ~ 24x38 with the garage door on the right side of the 38'. Directly to the left of the garage door is a standard swing entrance door. As you walk in, my compressor is directly to the left as is my "L" shaped workbench (8' long on both walls). The tube heater is against the far wall aimed towards the garage door at a 45* angle.

Back to the location question. I had thought about putting the stat against the same wall where the doors reside....but above my workbench. My only concern though is catching cold air from behind the insulation affecting the temperature of the stat as this is an outside wall. Another thought would be to mount it under the front lip of the workbench ~ 2' away from the wall. That location however is not kid friendly....but may provide a more accurate representation ambient room temps.

Any thoughts?

FYI, this is a 120v line voltage thermostat setup.

Keep it off an exterior wall, and I would attempt to put it out of the direct airstream of heated air from the heater. Besides that... wherever access is good is fine. The thermostat's actual accuracy isn't important, just the precision.

It doesn't matter if the thermostat says "bananas" when it's 45 degrees and it kicks on the heater. What's important is that when it hits 45 degrees, it kicks on the heat.

So keep it from getting abnormal input... ie, exterior wall and in direct airflow.

Well, after I gave it some thought....I put it on the exterior wall. It's the only place conceivable that was out of the way enough to avoid any accidental bumps by myself or the kids. Hopefully the plastic single gang along with the insulation and pegboard will be enough to isolate the temps a bit. If it reads a bit low at all times...I really don't care as long as they are consistent. It is out of the way of any major source of airflow, so well see how it works.

You could have issues with consistency because of the exterior wall. You could just put a piece of rigid insulation behind it. That would probably isolate it enough to not worry about it. Heck, a piece of styrofoam would be fine.
