A simulation study was done in a water heater by varying the position of the heating coil inside the chamber and initial temperature by electric energy to validate the thermal performances and time-consuming. Numerical reading was compared with experimental work. Position of the heater, placed in two different locations. Horizontally placed in the a) ground surface, b) the middle-point of the chamber. The investigation focused on the analysis of the temperature distribution in the chamber by the heater and higher temperatures attained by varying initial electric energy within a short duration. The result reveals that the heating rod at the midpoint of the chamber has produced symmetrical heat distribution throughout the chamber and experimental results of electric energy 3 KW were compared with simulation and yield higher temperature in rapid duration.
