I honestly think that you should reconsider this and at the very least run a dedicated 220 line if you are set on electric heat. In all my years in the HVAC field I have yet to run across a 110VAC rated heater that would sufficiently do what it is that you want. I know that you mentioned that the walls are insulated on 3 sides but you also have factor the ceiling height as well as the floor into your heat loss. If your floor is concrete, as most garages are, then that will be a huge load on that little heater and you may find that it runs continuously. This brings up another issues because of the fact that a 110VAC heater is likely to draw a pretty good amount of amperage and if you try to operate anything else on that circuit it would most likely trip the breaker.

You mention that your decision to stay with electric heat is due to “avoid flames” but you have to remember that most electric heaters will have their heat elements open to the surrounding environment. Any saw dust, or other combustible material for that matter, will react the same whether it is electric or gas fired.
