AN ELECTRICAL FLUID HEATER

A fluid heater (100) includes at least one heating element (10) and at least one casing (20). The casing (20) includes a first and a second portion (20a) and (20b), a partition groove (22), an inlet and an outlet (24) and (26). The first and second portions (20a) and (20b) are assembled to define an enclosure receiving the heating element (10). The partition groove (22) divides casing (20) into a first chamber (20d) receiving fluid from the inlet (24) and defining a first pass "A" and a second chamber (20e) delivering fluid to the outlet (26) and defining a second, return pass "B". The casing (20) is formed with an intermediate connecting portion (28) to define an U-turn trajectory "C" forming fluid communication between the first and the second chambers (20d) and (20e) along plane of heating element (10) and extending in longitudinal direction along lateral side of heating element (10).
