An electrical fluid heater comprising: • a pair of end plates (10, 20), wherein o a first end plate comprises an inlet for ingress of fluid into and an outlet for egress of fluid out of the electrical fluid heater from same side of the electrical fluid heater and is adapted to cause the fluid to follow a U-turn trajectory between the inlet and the outlet; o a second end plate formed with different portions (20a, 20b) that are in fluid communication with each other; • a plurality of electric heating elements; • a plurality of intermediate plates stacked and arranged between the first and the second end plates and respectively, the electric heating elements being sandwiched there between, adjacent intermediate plates defining fluid flow passes adjacent the at least one corresponding electric heating element to permit heat exchange between the fluid and the at least one corresponding electric heating element, each intermediate plate being divided into different sections (40a, 40b) respectively corresponding to the different portions (20a, 20b) of the second end plate, wherein first sections of the intermediate plates define fluidly coupled first fluid flow passes adapted to receive fluid from the inlet for heat exchange with the electric heating elements and second sections of the intermediate plates define fluidly coupled second fluid flow passes adapted to deliver fluid to the outlet after heat exchange with the electric heating elements; characterized in that the second end plate comprises multiple fluid deflecting walls on its surface adapted to promote an homogeneous distribution of fluid received in a first portion of the second end plate and homogeneous distribution of the fluid from the first portion to a second portion of the second end plate in the U-turn trajectory between the inlet and the outlet. • a pair of end plates (10, 20), wherein o a first end plate comprises an inlet for ingress of fluid into and an outlet for egress of fluid out of the electrical fluid heater from same side of the electrical fluid heater and is adapted to cause the fluid to follow a U-turn trajectory between the inlet and the outlet; o a second end plate formed with different portions (20a, 20b) that are in fluid communication with each other; o a first end plate comprises an inlet for ingress of fluid into and an outlet for egress of fluid out of the electrical fluid heater from same side of the electrical fluid heater and is adapted to cause the fluid to follow a U-turn trajectory between the inlet and the outlet; o a second end plate formed with different portions (20a, 20b) that are in fluid communication with each other; • a plurality of electric heating elements; • a plurality of intermediate plates stacked and arranged between the first and the second end plates and respectively, the electric heating elements being sandwiched there between, adjacent intermediate plates defining fluid flow passes adjacent the at least one corresponding electric heating element to permit heat exchange between the fluid and the at least one corresponding electric heating element, each intermediate plate being divided into different sections (40a, 40b) respectively corresponding to the different portions (20a, 20b) of the second end plate, wherein first sections of the intermediate plates define fluidly coupled first fluid flow passes adapted to receive fluid from the inlet for heat exchange with the electric heating elements and second sections of the intermediate plates define fluidly coupled second fluid flow passes adapted to deliver fluid to the outlet after heat exchange with the electric heating elements;
