Are you confusing the two liquids not coming in contact with each other? The a/f or raw water coming from the engine and the fresh water? I agree with JimG. I think you'll find the heating element is immersed in the fresh water side.No liquid touches the heating element
I don't bypass. I drain and blow the system out. I leave all the faucets open.
