A washer fluid system including a reservoir having a discharge for transferring fluid through a transfer hose via at least one discharge nozzle aligned to discharge the fluid onto a windshield of the vehicle. The device includes a housing having an inlet to receive fluid from the transfer hose at a point downstream from a discharge motor and an outlet to discharge fluid to the transfer hose for discharge by the nozzle. Fluid is held by a container operably connected to the inlet and the outlet. A heating element, preferably powered by the vehicle's electrical system, most preferably only when the ignition for the vehicle is in the on position, heats fluid in the container to a temperature which does not exceed a predetermined maximum temperature such as 50.degree. F. above ambient temperature. Insulation is provided for insulating the container in the housing. The heater device is preferably positioned on the fire wall of the vehicle proximate a pair of discharge nozzles for the windshield of an automobile or the like by a bracket. Preferably the housing and the container are axially concentric spaced apart cylinders, the inlet and outlet are tubular hoses axially aligned therewith, and the insulation comprises a hollow cylindrical filling the space between the housing cylinder and the container cylinder.
In a washer fluid system in a vehicle, said system including a fluid reservoir having a discharge pump for transferring fluid from said reservoir through a transfer hose, at least one discharge nozzle aligned to receive fluid from said transfer hose to discharge said fluid onto a windshield of said vehicle, a heater device comprising:
