Aqua/Hydro Hot retrofit?

[PancakeBill]

Anyone ever look into a retrofit on one of these systems?  We have a gas coach and I know there is a Propane version, vs. the diesel version.  Would it be easier to just a buy a new coach with one, or is there anyway to add one to an existing coach.  I would think plumbing would be a major issue.

It's always easier to buy a new one that already has the system installed, but not the cheapest way to go.  I had a coach that had a propane tankless that worked pretty well. If you have a gas heater already, it wouldn't be too bad to convert. 

The Aqua Hot would require running a new diesel line from the tank, which may be a real pain.

He's got a gas coach, Marty, which is another problem. And since Aqua Hot does both hot water and furnace, it's going to require a lot more than just a new fuel line for the AH -- it needs tie-ins to the fresh water system, the heating system and, if you want the heating while rolling down the road it also needs a tie-in to the engine, and it still might require a kluge or two, not to mention that I'd hate to use gasoline in the burner (propane maybe? Still another kluge). It's probably cheaper and easier to get a coach with it already built in, which probably means going to a diesel coach.

Little more research, the propane fired tankless  looks like a better idea.  I believe that AquaHot had one for a gas coach that used propane, not gasoline.  I am searching now for tankless that is both propane and electric. 

BTW, I have a Winnebago with Mptoraid, so driving, keeps water hot in tank, but if I switched to tankless, would have to cap off that line.
