The sounds you were hearing from the water heater may be the result of a build up of scale on the electric heating element if you've been using hard water in the system. Because the scale is both an insulator and somewhat porous, it's possible for there to be localized boiling right on the element's surface. The periodicity of the sound is probably correlated to the cycling of the electric element. I remember hearing something similar when I lived in areas that had very hard water and had an electric water heater in my house.
