6m x 6m x 2m garage = 72m3 air
Air weighs 1.22Kg/m3 so 88Kg
Heat capacity of air is 1005 J/Kg/oC
So a one degree rise would require 88 x 1005 = 88,440 J
Your heater is putting out 3000 J/s so should take just under half a minute to go up 1oC.
If the front grille isn't warm, the heating element is broken and it's just a fan.
To the original point about how to make the garage warmer - Insulate ceiling, walls and (if you can, floor); and stop drafts. And if your dust extraction goes outside you'll never win!
