A windshield washer fluid heater having a housing which defines a housing chamber. A subhousing is disposed in the housing chamber. This subhousing is constructed of a thermally conductive material and divides the housing chamber into an outer housing chamber between the housing and the subhousing, and an inner housing chamber inside the subchamber. The outer housing chamber and inner housing chambers are fluidly isolated from each other. A core is disposed in the inner housing chamber thus forming an annular fluid chamber between the core and the subhousing. A washer fluid inlet on the housing is open to one end of the annular chamber while a washer fluid outlet at the other end is open to the other end of the annular chamber An engine coolant inlet is open to the outer chamber while an engine coolant outlet is also open to the outer chamber at a position spaced from the inlet so that fluid flow into the coolant inlet flows through the outer housing chamber and to the coolant outlet. Alternatively, an electric heater is used to heat the housing chamber containing the annular fluid chamber.
