Going to start getting cold here (Atlanta) and I'll need to winterize the coach before too long. I have a 2011 Phaeton with a tankless water heater. I looked through the manual but found nothing referring to this style heater in the winterization info. Are there any special steps one should take to properly winterize it or does just draining the water tanks take care of it? Thanks.
By the way my wife wanted this feature and I was a bit against it (I had heard there were problems with it) but I must fess up that I really like having that unlimited supply of hot water! (Oh, no, the wife is right again!)
