I know we are still in the warm part of the year, but I am starting to think about the cold temps and my precious MPG's already. Let me preface by saying I live in Lincoln, NE. It obviously doesn't have quite as cold or long winters as our friends to the north, but we still can have pretty nasty winters some years. That being said, would an EBH be right for me? My Prius is kept in a garage of our split level home in the spot closest to the basement. On another note, I called our local Toyota dealership to ask about cost of parts and labor and they said about $120 total. However, the tech that was working at the time said Prius' don't need EBH since there is a preheated resevoir of something or other. Any truth to this? Thanks for any and all help!
