A pump and heater assembly can include an electric motor, a pump, one or more resistive heater elements, a control module with switching electronics usable to control operation of the electric motor, and a flowpath through which a coolant fluid is flowable fluidically passing to a first manifold downstream of the pump, to both first and second flowpath segments branching from the first manifold, and to a second manifold downstream of both the first and second flowpath segments. The first flowpath segment passes proximate to the heater elements to enable heating of a portion of the coolant fluid present in the first flowpath segment. The second flowpath segment passes through the control module proximate to the switching electronics to enable cooling of the switching electronics by a portion of the coolant fluid present in the second flowpath segment. The first and second flowpath segments can be arranged fluidically in parallel.
