Abstract: Abstract This heater is designed for the heating of a continuous flow of most type of fluids.  However, for  simplicity  purposes  of  discussion  of  the embodiment of  this  invention,  we will  use water, probably  the  most  commonly  used  of  fluids,  to discuss the uses and applications of this invention. A tankless,  flow-through electric water heater  (7) whose housing is designed for modular application, where serially connected modules (8) define the path of  the  fluid  being  heated,  in  this  case  water, through the heater from inlet (10) to final outlet (14).     Each  module  (8)  contains  two  separate chambers  and  each  chamber  is  provided  with  an electric immersion type heating element (40).   The first and last chambers will also have a temperature sensor   (55)   which  will   signal  an  electronic temperature control system (106).   The temperature in the first and last chambers energize each heating element (40) of each chamber for a period of time proportional to the temperature difference between first   chamber   and   the   desired   set   leaving temperature  of  the  water,  which  is  set  by  an adjustable  temperature  controller  (potentiometer) (51), included in this control system.  This control system also has a minimum setting point for a "no flow"  condition  or  for  the  prevention  of  water freezing, where extreme weather conditions exist.
