Or maybe two insulated tanks? Large tank & small tank both heated by power from the grid. When car has sat unplugged for a long, long time = no heat stored in insulated reservoir tanks, close valve to take large cold tank out of loop? 12V heat element in small tank. Haven't really thought out the plumbing.
