Electrode for an instantaneous water heater and water heater.

摘要

"The electrode to an instantaneous water heater and water heater instant." A water heater in line, using electrically conductive polymeric structures for electrodes (48, 49).The area of the electrodes confronting each other can be varied and, thereby, the temperature at which the water is heated can be variably adjusted.The heat is not generated by the electrodes, but instead by the water resistance to electrical current flowing between them.Although the electrodes may be moved in relation to each other.Preferably they are fixed and a plate of door power electrically conductive (47) can be ajustavelmente placed between them to variably adjust the total areas confrontanteS.An obstructing a bulldozer in the field (46, 53) can be provided at the entrance and exit of the heater housing, to prevent the output electric current of the electrodes of the heater.And also non - conductive grounding grids (43, 57) in position for secondary safety.
