In a word...no.

I say this not to trump your good fortunate and inexpensive heater, but because it's just not big enough. My shop is only 12 x 24 and is well insulated. When I say well I mean the bottom is banked with haybales outside, the walls have R-19 insulation, the ceiling has an R-38 factor, and every possible draft is blocked with "Great Stuff" to keep the cold Maine winters at bay. Even as tight as my shop is, that heater won't keep up with anything below 25º. Even if I run the thing the night before to "build the heat up", anything below 25º and its just to cold to work in there.
Adding insult to injury is the amount of fuel this thing consumes. Even at 25º outside temps, the thing burns 7-10% of fuel a weekend. Since I am trying to heat my shop, the things burns the same fuel if its 40º outside or if its -40º outside, it just means the heater has no way to recover the heat that is lost at that temp. Now imagine a bigger space, unheated. Granted most peoples shops are located in more fair weather climates than Maine, but still 20º is 20º, and twice a big of a space at 40º uninsulated means just about the same thing. I doubt this heater would do much for you.
The final insult of this heater is the fact that it produces an amazing amount of moisture. Not only does this heater NOT heat my shop, all it does is pump in moisture when it is running. Its a double whammy because when the temps dip to 20º, and my heater has no way to keep up, my tools really begin to rust. Firing up the heater only makes my shop tools rust that much quicker.
I will say however, I do plan on keeping the heater. I want to replace my shop heater with a bigger heater then use the smaller one for my snowmobile shed. That is only 8 x 12 so the heater should keep up with that small space.
Sorry to be the one to deliver the bad news.
If I was you, and you already are allowed to use wood heat in an outbuilding (my insurance company says no way), then I would consider adding a woodstove to your shop. I can't say for sure because woodstoves really depend on a ton of factors based on a case by case basis.
I have no intention of traveling from birth to the grave in a manicured and well preserved body; but rather I will skid in sideways, totally beat up, completely worn out, utterly exhausted and jump off my tractor and loudly yell, "Wow, this is what it took to feed a nation!"
