    This is certainly do-able, and is on my list of things to do. My engine
    heat goes to a small bus heater in the cabin, but is not in any way
    connected to my fresh-water system, so I don't get any hot water while
    underway. I do have a Webasto diesel furnace with the coolant lines
    plumbed through an AC hot-water tank that will give me enough piping hot
    water in 15 minutes for several showers and dishes, as well as the cabin
    heat from it's bus heaters. The AC heater only really gets the water
    very warm.

    At the last boat show I talked to one of the exhibitors who said, for a
    couple of hundred bucks, I could get an inline heat exchanger that I
    could use to provide an interface between the engine heat loop and the
    furnace heat loop, so that I could get hot water underway from the
    engines, but I could also use the furnace to pre-heat the engines if I
    wanted. He said it's fairly common.

    Now I just have to get to it...
