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.
