The invention relates to an electrode heater. In plane of horizontal cross section of its body made of thermo-stable water-permeable insulating material that can sustain pressure of liquid, having a form of a cylinder that is arranged in vertical position, in three equally spaced openings movable phase electrodes are fixed by means of hydro-insulation clutches. The electrodes are connected to voltage source. At the both ends the body is closed by metal covers connected to each other by means of pins, earthed and connected to zero phase of the voltage source. The lower cover of those has a branch pipe for supply of cold water and can have stems for placement on floor, and the upper one – a tube for discharge of heated water, between the covers and the body thermo-stable hydro-insulation pads are placed, with openings coaxial to the body and the openings of the tubes of the covers. |
