They sure don't give those systems away do they. Most people around here have the Aqua-Hot's, I personally am not all that knowledgeable on them but am willing to delve in on the subject to help you out. I know many owners who do have the Aqua-hot and I know others who have the Wabastos unit's, which I believe are much more common place on Wanderlodges and Bus Conversions. The Proheat is a good quality unit and used a bunch by trucking fleets do to being much more conservative on fuel consumption. I have a hunch the Proheat uses less fuel to accomplish the same good, but I will have to do some research and talk to some friends in the industry.

I would think putting an aquahot back in would be the easiest. Doesn't your system actually use some Wabastos components, I'm thinking the system I looked at in NewellCrazy's coach was a marriage of the two. I'll call my friend tomorrow and see what maybe I can find out. I'm also thinking maybe we can get a second opinion from another Aqua-Hot expert. I'm sending you a PM.
