I've never messed with heating windshield fluid because I rarely use it in any condition (it evaporates out of the tank mostly). It seems like trying to raise the temperature of the ocean by throwing a pot of hot water into it- too little, too late. Consider the masses of the components involved and the cooling they are subjected to.
The important thing is to have a warm windshield. For that you need a good defroster. For that plugging in an engine heater and having a grille block and an engine blanket are the best things to do, along with perhaps a safely positioned plug-in space heater aimed at the windshield before departing.
Take all that junk off the dash so the vents are unobstructed. Sometimes it really does help to put the visors down to help keep the defroster air flowing against the glass rather than dispersing into the vehicle. And it helps to reduce the causes of windshield fogging, mainly breath (crack a window or vent window a bit) and wet floors (kick the snow/water off your shoes and shake the floor mats out whenever they're wet).
