1. A cassette positionable within a cavity of a dialysis machine, the cassette fluidly connectable to a patient and a dialysate source for transferring a dialysate therebetween, the cassette comprising:
a fluid flow channel defined by a conduit, wherein the dialysate flows from a dialysate source through a first portion of the conduit having a first cross-section to a second portion of the conduit having a second cross-section, wherein the first cross-section is less than the second cross-section;
a heating element in thermal communication with an outer surface of the second portion of the conduit to conduct heat through the conduit into the dialysate; and
a nozzle disposed in the first portion of the conduit and having at least one opening to spray the dialysate about the circumference of an inner wall of the second portion of the conduit to provide increased heat transfer from the heating element to the dialysate.
