Motorhomes use a seperate water heating source for the hydronic heat. They use an "instantaneous" water heating system like the Hydro Hot. They are a diesel or propane fired system that work like a water tube boiler, IIRC. Very temperamental system that doesn't always work like they should. Installation needs to be damned near perfect to get them to work correctly. Very pricey, and they suck up the fuel too.

When they work, they are great. Just seems like we had them coming back into the shop waaaay too often. For someone with the time, money, and patience, it could work out for the best. Check them out at www.hydro-hot.com

Go with a 10 gallon. DSI and 120vac element. 120 element will keep the water hot when not in use, but propane has a faster recovery rate for when the water is flowing.

What flavor generator? Onan makes a controller that works with theirs.

That GenerJunk is gonna be loud.... Looooong straight pipe with the Onan muffler on the end would help.
