I was reading over on Roger Berke's forum(he's a guru member). He was explaining how the AquaHot unit heats the water and the coach interior that I found interesting. The water is heated by sending the water through copper coils that wind through the coolant tank and then routed out to the faucets. In contrast the coach is heated by routing the heated coolant from the coolant tank through the heat exchangers and then blown into the coach using fans.

Hope this clears up any confusion......................
