I don't think you need a vent for the electric only, you're going to need a place for the pressure relief valve to blow off if it needs to. I would guess a hole through the floor with a 1/2" pipe would do just fine (that's what the one in my house has). Just going to depend on how it's set up. Is your water heater one of the small ones that you put in houses or is it specifically for rv/trailer use?
