The principle of continuous 'pass-through' heating is effective, however, only when

hot industrial water is drawn or distributed. To use the pre-heater operating on the principle of continuous flow heating to heat the water contained in the tanks even when no industrial water is drawn for use, the space acting as the tank of the post-heating chamber can be
