An electrode-type water heater or steam generator constructed from only three different manufactured parts includes an electrically non-conductive housing formed from a pair of complementary identical open-face housing sections. The housing sections each have a plurality of spaced grooves on the interior surface thereof and a port in one end wall. One of the housing sections is inverted and secured face-to-face to the other housing section to form a hollow housing having an inlet port in one end, an outlet port in its other end and a series of spaced, parallel, continuous grooves on its inner surface. A plurality of identical disk-shaped carbon electrodes are each supported in a different one of the continuous grooves and are apertured to allow flow of water through the housing from the inlet port to the outlet port. Identical electrical connectors are provided for energizing the electrodes and each passes through an aperture in the side wall of the housing into a different electrode, with each housing section having a connector apertures communicating with alternate grooves.

An instantaneous electric hot water heater comprising: an electrically non-conductive housing formed of two identical complementary members, each of which is provided with sidewall means open at one side and end walls, said sidewall means having spaced apart grooves formed on the interior surfaces thereof parallel to said end walls and apertures extending through said sidewall means into alternate ones of said spaced apart grooves, and one end wall having a port formed therein, one of said members being inverted and joined to the other member with open sides thereof facing each other to form a water-tight hollow housing having a port in each of the opposite ends thereof and in which the grooves formed in each member are aligned and form a plurality of spaced apart continuous grooves on the interior surface of said housing; a plurality of electrodes extending transversely across the interior of said housing, each such electrode being supported in a different groove of said plurality of continuous grooves formed in said housing and being adapted to make electrical contact with an electrical connector projecting through an aperture in the sidewall of said housing into the groove, each electrode being provided with a plurality of apertures for the passage of water through the electrode; and a plurality of electrical connector means, one for each of said electrodes, each of said connector means projecting through an aperture formed in the sidewall means of said housing into the edge of a different electrode.
