No No No, the heating coil in the resevoir circulates coolant from the engine. It is not electrical. It's a fancy little piece of plumbing inside the washer bottle. Runs off of the bypass side of the cooling system so it gets hot at about the same rate as the engine side of the thermostat. As far as I can tell, there is always coolant flowing thru that little tube so I guess that it's always "on".
