At +30 you don't need a block heater. It's a waste of power to use one
at temperatures above +10 F or so. No it won't warm the engine up
enough that the temp guage will come up off the pin. Most temp guages
only start to come off the pin at about +140 F

If it's a warm car interior you're after, get a 115V car heater and a
timer that will start the heater about an hour before you plan to use
the car.
