A new encapsulated heating element fluid heater for heating a fluid such as water. The inventive device includes a vessel and an end cap. The end cap has a plurality of bores therethrough extending between the first and second ends of the end cap. A plurality of elongate heating element rods extend through the bores of the end cap and each heating element rod has a heating portion outwardly extending from the first end of the end cap and an electric coupling portion outwardly extending from the second end of the end cap. The first end of the end cap is inserted into an open end of the vessel such that the heating portions of the heating elements extend into the vessel. The end cap is then welded to the end of the vessel.
